Treatment for patients in right heart failure typically consists of inotropes to bacteria 500x magnification ampicillin 500 mg with amex augment right ventricular contractility bacteria zapper for face discount ampicillin 250mg on line, fluid management infection limited mobile al generic ampicillin 500mg mastercard, hyperventilation do antibiotics for acne cause weight gain discount ampicillin 250mg on-line, and pharmacologic modulation of pulmonary vascular resistance. High levels of static electricity may damage and/or interfere with the electrical parts of the system and cause the Left Ventricular Assist Device to stop. HeartMate 3 Left Ventricular Assist System Instructions for Use 6 13 6 Patient Care and Management Using the Shower Bag Although the external components of the HeartMate 3 Left Ventricular Assist System are moisture resistant (including a properly connected Driveline Modular inline connection), they are not waterproof. Take care to protect external system components from water or moisture?outside in heavy rain or snow, and always for every shower. If the external system components have contact with water or moisture, the patient may receive a serious electric shock or the pump may stop. When taking a shower, the patient must shield all external components from water by placing them into the water resistant Shower Bag. This includes protecting the System Controller, System Controller power cables, Driveline, and two HeartMate 14 Volt Lithium Ion batteries with attached battery clips. The Driveline and System Controller power cables exit the Shower Bag through double zippers along the side. The Shower Bag has an adjustable shoulder strap for optimal positioning to reduce pulling on the Driveline exit site. Pulling on or moving the Driveline can keep the exit site from healing or damage an already healed exit site. Damage to the Driveline or cables could cause the Left Ventricular Assist Device to stop. Placing objects other than HeartMate 3 equipment in a wearable accessory may damage the accessory. Clip the shoulder strap to the Shower Bag using the two rings located on the top of the bag (Figure 6. Adjust the shoulder strap so the Shower Bag fits the patient without pulling on or moving the Driveline. Make sure that the System Controller power cables and Driveline are not twisted (Figure 6. Unclip the top of the Shower Bag by squeezing the clip prongs together and pulling the slide out of the buckle (Figure 6. Place the batteries, battery clips, and attached power cables into the Shower Bag (Figure 6. When putting the System Controller into the pocket, the end without the cable goes in first and the user interface should be facing up. Slide the System Controller into the pocket on the inside cover of the bag, cable free end first and with the user interface facing up (Figure 6. HeartMate 3 Left Ventricular Assist System Instructions for Use 6 19 6 Patient Care and Management Figure 6. Prepare to close the cover by positioning the power cables inside the water resistant enclosure (Figure 6. Make sure the System Controller power cables are inside the bag, and the Driveline exits through the protective red tabs (Figure 6. Close the lid over the zippered enclosure, carefully positioning the Driveline down the side of the bag (Figure 6. Adjust the shoulder strap so that the Shower Bag does not pull on the Driveline exit site. Apply a sterile dressing to the exit site, using an sterile technique (see Caring for the Driveline Exit Site on page 6 8). Open the Shower Bag using the clip and buckle for the lid, and the left and right zippers for the top. Remove all equipment from the Shower Bag enclosure; place the equipment in a clean, dry location. Transfer system components to a wearable accessory such as the holster vest, Consolidated Bag, belt attachment, or System Controller Neck Strap (see Wearing and Carrying System Components on page 6 27). Allow the Shower Bag to drip dry completely before using it again (see Cleaning HeartMate Wear and Carry Accessories on page 8 9). See Cleaning and Maintenance on page 8 4 for complete instructions on caring for all wearable accessories, including the Shower Bag. The Left Ventricular Assist Device will stop if the Driveline is disconnected from the System Controller. If the Driveline is disconnected, reconnect it as quickly as possible to restart the Pump. If the System Controller does not work, replace it with a backup System Controller that is programmed with patient specific settings. HeartMate 3 Left Ventricular Assist System Instructions for Use 6 23 6 Patient Care and Management Showering If the patient obtains doctor approval to shower, these instructions must be used each time. Keeping your Driveline Exit Site Dry It is important to keep the Driveline exit site dry while showering. This helps prevent infection and helps extend the use of the driveline management system. When applied correctly, covering the driveline management system with a moisture barrier consisting of a sheet of multi purpose sealing wrap, sealed with adhesive tape on the edges, should keep moisture away. Never expose the System Controller, Batteries, Power Module, or Mobile Power Unit to water. The HeartMate? GoGear? Shower Bag must be used while showering to keep the System Controller and Batteries dry. Make a sheet of multi purpose sealing wrap large enough to completely cover the drive line management system with at least six inches on all sides. Center sheet of multi purpose sealing wrap over the driveline management system and stick to skin (see Figure 6. Rub the sheet of multi purpose sealing wrap into place with fingers so that it is smooth to the skin with no gaps. Seal around the edges of the sheet of multi purpose sealing wrap with the tape (see Figure 6. Apply the tape to all four edges of the sheet of multi purpose sealing wrap so that there are no gaps. Check all edges and make sure the sheet is completely stuck to the skin with no gaps. Gently peel away the multi purpose sealing wrap and tape from the skin (see Figure 6. HeartMate 3 Left Ventricular Assist System Instructions for Use 6 25 6 Patient Care and Management Figure 6. If the driveline management system gets wet, change it as instructed in the previous sections. Wear and Carry Use Accessory Worn around the neck or across the body; holds the System System Controller Controller when connected to the Power Module, the Mobile Power Neck Strap Unit, or during battery powered operation. Worn around the waist, on a belt; holds the System Controller when Belt Attachment connected to the Power Module, the Mobile Power Unit, or during battery powered operation. Worn on a shoulder and stabilized around the waist; used to carry the System Controller and 2 batteries/battery clips together in a Consolidated Bag single bag during battery powered operation. Worn around the shoulders and under the arms; holds the System Controller and 2 batteries/battery clips during battery powered Battery Holster operation. Worn around the shoulders and under the arms; holds the System Controller and 2 batteries/battery clips during battery powered Holster Vest operation. Common activities may include, but are not limited to: exercising, dressing, traveling, playing with children, gardening, hiking, cooking, and dancing. The patient should consult with his or her doctor about daily activities and any changes in activity level or routine. Use two attachment points to suspend the System Controller, either vertically or horizontally (Figure 6. Choose two attachment points on the System Controller, for either vertical or horizontal wearing of the Neck Strap. Slide the rubber strap on the Neck Strap through an attachment point on the System Controller (Figure 6. HeartMate 3 Left Ventricular Assist System Instructions for Use 6 31 6 Patient Care and Management Figure 6. To buckle the strap, thread the rubber strap through the metal buckle on the Neck Strap.

All equipment and supplies should be identifed and stored in a manner that prevents use by or for other patients 700 bacteria in breast milk order ampicillin 500mg otc. Additional cleaning measures or frequency may be required in situations when continued transmission of specifc infectious agents topical antibiotics for acne uk order ampicillin 250 mg on-line. Assess the effcacy of disinfectants being used virus 85 cheap 250 mg ampicillin with mastercard, and if indicated antibiotic resistance and superbugs generic ampicillin 500mg overnight delivery, select a more effective disinfectant. Clean all horizontal and frequently touched surfaces at least twice daily and when soiled. When precautions are discontinued or the patient is moved, terminal cleaning of the room or bedspace and bathroom, changing of privacy curtains, and cleaning or changing of string or cloth call bells or light cords is required. Educate patients, their visitors, families and decision makers about the precautions being used, the duration of precautions, as well as the prevention of transmission of disease to others with a particular focus on hand hygiene. Instruct visitors who are participating in patient care about the indications for and appropriate use of personal protective equipment (barriers). This may not be necessary for parents carrying out their usual care of young children. Instruct visitors to speak with a nurse before entering the patient room, to evaluate the risk to the health of the visitor, the risk of the visitor transmitting infection, and the ability of the visitor to comply with precautions. If the visitor must visit more than one patient, instruct the visitor to use the same barriers as the health care workers and perform hand hygiene before going to the next patient room. Determine the duration of precautions on a case by case basis for patients with prolonged symptoms or who are immunosuppressed. Discontinue precautions only after the room or bedspace and bathroom have been terminally cleaned. Handling of Deceased Bodies Routine Practices, properly and consistently applied, should be used in addition to Contact Precautions for handling deceased bodies, preparing bodies for autopsy or transfer to mortuary services. Special Considerations for Antimicrobial Resistant Organisms in All Health Care Settings. In acute care inpatient facilities, Routine Practices and Contact Precautions are recommended for infection or colonization. In addition, some facilities and organizations may choose to include precautions for persons at risk of colonization, pending screening results, particularly in outbreak situations. Decisions will need to be made locally, considering the specifc microorganism, the patient population, and local experience with duration of colonization. Recognize that patients placed on Contact Precautions may have fewer contacts with health care providers, and this may reduce their quality of care. Perform a point of care risk assessment to determine patient placement, removal from a shared room or participation in group activities on a case by case basis, balancing infection risks to other patients in the room, the presence of risk factors that increase the likelihood of transmission, and the potential adverse psychological impact on the infected patient. Wear gloves if direct personal care contact with the patient is required or if direct contact with frequently touched environmental surfaces is anticipated. This includes bathing and toileting facilities, recreational equipment and horizontal surfaces in the patient room, and in particular, areas and items that are frequently touched. They should refect the local experience with particular antimicrobial resistant organisms and be fexible enough to accommodate the characteristics of different antimicrobial resistant organisms. It is important to collaborate with other local health care organizations to design a comprehensive and consistent program. Controlling transmission is primarily the responsibility of direct caregivers through hand hygiene and appropriate use of gloves. Ability to maintain hygiene by the patient and caregivers, individualized activity restrictions, selection of low risk roommates, and environmental cleanliness also require consideration. Minimize contact between symptomatic patients and others by minimizing time spent in waiting rooms. Cleaning and Disinfection of Non Critical Patient Care Equipment and Patient Environment? Clean equipment and surfaces in direct contact with the patient or infective material. Place contaminated, reusable, non critical patient care equipment in a plastic bag for transport to a soiled utility area for reprocessing. The same cleaning measures should be performed when the current patient is staying in the room, when extensive environmental contamination has occurred from the patient (diarrhea or fecal incontinence not contained by diapers, copious wound drainage, copious uncontrolled respiratory secretions or sputum). Special Considerations for the Care of Patients with Antimicrobial Resistant Organisms in Ambulatory Care Settings. If asymptomatic, Routine Practices, properly and consistently applied, are suffcient. Special Considerations for the Care of Patients with Antimicrobial Resistant Organisms in Home Care. Requiring proof of screening for antimicrobial resistant organisms before service is not advised. For asymptomatic patients, Routine Practices, properly and consistently applied, are suffcient. In some jurisdictions, such collaboration may also be appropriate with the local funder of home care services. Remove gloves and gowns when patient care is broken and completed, then immediately discard and perform hand hygiene. Wrap the patient in a sheet in the examining room, to minimize contact with personnel and the environment. Consider conditions as listed in Routine Practices for priority for single transport. Special Considerations for the Care of Patients with Antimicrobial Resistant Organisms in Prehospital Care. Adhere to modifcations of Contact Precautions for prehospital care, as described above. Develop a system to identify patients with known or suspected acute infections that require Droplet Precautions. When a mask is worn, the patient can remove the mask once accommodated in the room. Health care workers should avoid touching the mucous membranes of their eyes, nose and mouth with their hands to prevent self contamination. Droplet Precautions, in addition to Routine Practices, are suffcient for aerosol generating medical procedures when performed on patients on Droplet Precautions who have no signs or symptoms of suspected or confrmed tuberculosis, severe acute respiratory syndrome or respiratory infection with an emerging pathogen for which transmission characteristics are not yet known. In inpatient facilities, a single room with an in room designated toilet and sink is preferable, as it may be diffcult to maintain the recommended spatial separation of two metres between patients. If suffcient single rooms are not available, cohort patients who are known to be infected with the same pathogen and are suitable roommates. When the room must be shared and cohorting patients with the same pathogen is not possible: i) Avoid placing patients on Droplet Precautions in the same room with patients who, if they were to become infected, would be at high risk for complications or who may facilitate transmission. Draw the privacy curtain between beds to minimize opportunities for droplet spread. Ensure family members or designated visitors are able to comply with the required precautions. Ensure, assisting as necessary, that the patient performs hand hygiene before leaving the room. Personnel in the area to which the patient is to be transported should be aware of the status of the patient and of the precautions to follow. Provide personal protective equipment for Droplet Precautions outside the room or in the anteroom. Transport personnel should wear facial protection if the patient cannot follow respiratory hygiene. Wear and discard facial protection to prevent self contamination, as outlined in Routine Practices. In addition to the use of personal protective equipment described in Routine Practices: i) Wear facial protection. In a cohort of patients infected with the same microorganisms, Additional Precautions must be applied individually for each patient within the cohort. Cleaning of Patient Care Equipment Follow Routine Practices, unless Contact Precautions are also required, then follow Contact Precautions. Cleaning of Patient Environment Follow Routine Practices, unless Contact Precautions are also required, then follow Contact Precautions. Educate patients, their visitors, families and their decision makers about the precautions being used, with a particular focus on hand hygiene, the duration of precautions, and the prevention of transmission of disease to others.

Specificity indicates a tests? ability to antibiotic co - buy cheap ampicillin 500mg online accu rately classify people as negative who do not have anemia. Because most children in both sub populations were not anemic, the heightened specificity of the gravity method may have helped it to give more accurate results. Discussion Effective screening programs to assess the prevalence of anemia in vulnerable populations. A reliable, sensitive, low cost, safe, and rapid test for Hb measurement is urgently needed in low resource settings. Overall, the HemoCue1 gravity method was the most accurate and least biased among this pediatric population. The HemoCue1 wicking method and the Pronto1 device were found to overestimate Hb concentration among anemic children and underestimate Hb concentra tion among healthy children. The HemoCue1 wicking method is the approach recommended by the manufacturer, with specific instructions on proper methodology for blood sampling. Recent concerns about the accu racy and reliability of the method?thought to be caused by user variability and blood sampling techniques?has prompted an investigation into the use of the gravity method for blood sampling with the HemoCue1. As we found in this study, the HemoCue1 gravity method appears to be more accurate than the HemoCue1 wicking method. Additional studies with larger samples are needed to confirm this conclusion, and the mechanism by which enhanced accuracy is achieved warrants further investigation. It is possible that the transfer of blood samples onto a nonperme able surface changes the physical properties of the blood collected. Although the HemoCue1 gravity method provides potential improvement in measure ment accuracy, it brings additional operational challenges, especially in low resource settings. In addition, a clean surface is needed for the HemoCue1 gravity method, which in turn introduces additional medical waste and risks for the staff conducting the tests. Moreover, the effects of user variability and environ mental factors such as heat and humidity on the gravity sampling method have not been assessed. Future studies are needed to assess the operational feasibility of the gravity method. Noninvasive measurement devices are promising tools that may have significant advantages 1 over existing anemia screening methods. Noninvasive measurements can also increase patient and caregiver acceptability, reduce the risk of infection from contact with blood and sharps, and reduce the burden on supply and dis tribution since no recurrent consumables are required [14]. The study did not assess the value of additional indicators provided by the Pronto1 noninvasive device?SpO2 and pulse rate? which could potentially influence programs in their choice of methods. The benefits of nonin vasive screening and diagnosis are clear, and it is anticipated that refinements to these innova tions will continue to be made as user feedback and evidence on the performance of the devices is collected. This failure rate was higher than in previ ous studies with other Masimo devices. Although other studies have noted that participants with darker or calloused skin or in settings with high ambient light had higher rates of repeated measurements and device failures [18], this study did not support those findings. It is impor tant to conduct future studies to confirm our results and further assess other factors potentially contributing to detection failure. This study was limited in that it used a relatively small sample size within a controlled hos pital setting. Regarding generalizability, more research needs to be conducted with larger sample sizes in more diverse environments to better understand how noninvasive Hb mea surement devices in particular will be used, how well they perform under routine conditions, and the feasibility of integration into current public health programs in low and middle income countries. Further research is also needed to evaluate the acceptability and operational feasibility of the HemoCue1 gravity method of blood sampling, with blood sampling carried out in less controlled primary health care settings or during routine population surveys. The ultimate goal is to identify the most accurate, acceptable and affordable Hb measurement device that will lead to increased anemia testing and treatment. When making decisions about the most appropriate tool for anemia screening, anemia control programs must take into account and carefully weigh the tradeoffs in cost, safety, con venience, and accuracy.

The risk/benefit ratio of transfusion has been studied in randomized trials in few clinical settings. This large randomized trial found no benefit from liberal transfusion in either survival rates or in the ability to walk independently 60 days postoperatively. A large 2 3 randomized controlled trial and prospective observational studies have not only failed to show the benefits of a more liberal red blood cell transfusion policy in the perioperative and critical care settings, but have also suggested an increased risk of death in certain subgroups of patients who have been liberally transfused. Further studies are urgently needed, especially in individuals with underlying acute myocardial ischemia, in whom 4,5 conflicting results have been reported. Whenever the benefits of transfusion are not obvious based on hemoglobin concentration (Hgb of 7 10 g/dL) and the clinical picture alone, other data, if available, such as oxygen extraction ratio and Pv02 are useful adjuvants to determine the clinical necessity for blood transfusion. It is prudent to transfuse only in the presence of compelling clinical indications in individual patients. No universal trigger has been established for red cell transfusions that is deemed appropriate for all patients. In most healthy patients, oxygen delivery is thought to be adequate even at a hemoglobin of 7 g/dL. Many adaptive, physiological changes occur as a result of anemia, such as increase in cardiac output, altered blood viscosity, and coronary and cerebral blood flow. Some patients, such as the elderly, those who are already anemic, and those with underlying cardiac or pulmonary disease, may not be able to respond in this manner, and therefore tolerate anemia poorly. Exacerbation of blood loss through phlebotomy frequently contributes to anemia in the intensive care unit. Efforts should be made to minimize the frequency and volume of blood drawn by using pediatric size tubes and performing as many tests as possible on each sample. Maintenance of normovolemia is the single most important strategy for ensuring adequate tissue perfusion. However, it should be noted that such vital signs may be masked by anesthetic agents and other drugs. Hemoglobin Concentration the accuracy of hemoglobin concentration measured after acute blood loss is influenced by intravenous fluid resuscitation and time needed for equilibration. Blood loss and hemoglobin concentration must be evaluated, along with the risk of further bleeding, presence of coagulopathies, body temperature, and associated high risk factors, all of which may affect the decision to transfuse. The American Society of Anesthesiologists Task Force on Blood Component 7 Therapy recommendations based on hemoglobin concentration are: Hemoglobin > 10 g/dL transfusion is rarely indicated. Pharmacological agents to raise hemoglobin and reduce surgical bleeding should also be used as appropriate. Anemia Treatable by Non transfusion Therapy the cause of the anemia should be established. Transfusion should only be used under these conditions if the situation is life threatening, such as in the case of emergency surgery, trauma, or other acute blood loss.

The Mobile Power Unit surface temperature can become uncomfortably warm antibiotics lecture discount ampicillin 500 mg without prescription, especially when the room temperature is above 104?F (40?C) antibiotics liver buy ampicillin 500 mg line. Power On Symbol the power symbol is illuminated green when the Mobile Power Unit is powered and functioning properly. The yellow wrench symbol illuminates when the Mobile Power Unit detects Yellow Wrench a mechanical, electrical, or software issue with the system. When the yellow wrench illuminates, switch to two fully charged HeartMate 14 Volt Lithium Ion batteries. When the Replace Mobile Power Unit Battery symbol illuminates, replace the internal batteries in the Mobile Power Unit. You must install the Mobile Power Unit batteries before using the Mobile Power Unit. Never change the Mobile Power Unit batteries while the Mobile Power Unit is powering the HeartMate system. Switch to another power source, and then disconnect the Mobile Power Unit power cord from the power socket prior to replacing the batteries. Open the battery compartment cover on the rear of the Mobile Power Unit (Figure 3. If replacing batteries, gently pull the ribbon to remove the depleted batteries from the case. HeartMate 3 Left Ventricular Assist System Instructions for Use 3 41 3 Powering the System 7. Follow the orientation markings on the battery clip when inserting the batteries (Figure 3. Dispose of or recycle the depleted batteries in compliance with all applicable local, state, and federal regulations. Pull back on the end of the power cord to ensure a secure connection to the Mobile Power Unit (Figure 3. When initially connected to power, the Mobile Power Unit automatically performs a self test during which the green Power On? light turns on. The yellow wrench and the Replace Mobile Power Unit Battery lights flash and the Mobile Power Unit beeps twice. After the self test is completed, the green "Power On" light remains illuminated (Figure 3. If the green light still does not come on, the Mobile Power Unit may have a problem. The power symbol is illuminated green when the Mobile Power Unit is powered and functioning properly. Press down and hold the yellow button on the top of the plug to disengage the locking mechanism (Figure 3. Do not use the Mobile Power Unit when the patient may require monitoring using the System Monitor. Patients must always connect to the Mobile Power Unit before sleeping (or when sleep is likely), because they may not awaken to hear low power alarms for batteries (see System Controller Alarms on page 7 3). Do not allow the cable to come into contact with sharp edges, and use care to prevent it from being pinched or bent. Like the power cable connectors on the System Controller, the connectors on the Mobile Power Unit patient cable are also color coded (see Figure 3. When connecting the System Controller to the Mobile Power Unit patient cable, always connect white to white and black to black. Confirm that the Mobile Power Unit is ready for use (see Setting Up the Mobile Power Unit For Use on page 3 40).

Promptly align opposite half circles inside the white System Controller power cable connector and the white Mobile Power Unit patient cable connector (Figure 3. Promptly align opposite half circles inside the black System Controller power cable connector and the black Mobile Power Unit patient cable connector. Wrap the Mobile Power Unit patient cable around the Mobile Power Unit for storage (Figure 3. However, it should be inspected routinely to ensure the safest and best possible performance. For complete information about caring for the Mobile Power Unit, see Caring for the Power Module and Mobile Power Unit on page 8 7. Periodically, and as needed, use a clean, damp (not wet) cloth to clean the exterior surfaces of the Mobile Power Unit. On battery power, patients can enjoy activities outdoors or away from home such as shopping, gardening, or running errands. The batteries and attached battery clips can be worn in holsters, one under each arm, or across the body, in a bag, or in a pouch around the waist. The status of an individual battery can be checked at any time by pressing the on battery power gauge on the individual battery (see Checking Battery Charge Status Using the On Battery Power Gauge on page 3 56). Required Components Components for operating the HeartMate 3 system on battery power include the following: The HeartMate 3 Left Ventricular Assist System is optimized for operation with two batteries, but the system can run on only one battery for a very short period (minutes). For example, when switching from batteries to the Power Module or Mobile Power Unit (or vice versa), operation will continue on a single battery while connections are made. Before removing a battery from the Battery Charger, make sure that the battery has completed its charge or calibration cycle. The patient must always connect to the Power Module or Mobile Power Unit for sleeping or when there is a chance of sleep. Using damaged, defective, or expired batteries may reduce operating time or the pump may stop. After approximately 70 uses, HeartMate 14 Volt Lithium Ion batteries may need to be recalibrated. Calibration can take up to 12 hours, and only one battery can be calibrated at a time. Removing a battery before it is fully calibrated may result in a depleted battery. Dirty battery contacts on the 14 Volt Lithium Ion battery may prevent proper charging, which can affect operation. Use a lint free cloth or cotton swab that has been moistened (not dripping) with rubbing alcohol. Let the alcohol dry before using the batteries or battery clips, or before placing batteries into the Battery Charger. If batteries do not give at least four hours of support, take them out of service. If stored and used within recommended guidelines, HeartMate 14 Volt Lithium Ion batteries should be usable for approximately 360 use/charge cycles or for 36 months from the date of manufacture, whichever comes first. If the fluid touches your skin or eyes, wash the affected area with plenty of water and seek medical advice. See Storage and Transport on page 8 3 for complete storage guidelines, including great than 30 days. Metal objects touching the exposed battery contacts may cause an accidental short and a rapid discharge of the battery. Charging a New HeartMate Battery Before Use Every HeartMate 14 Volt Lithium Ion battery must be charged before being used for the first time. It takes up to four hours to charge a new battery, depending on the initial charge status of the battery. Batteries are charged in the Battery Charger, which can charge up to four batteries simultaneously. Charging a battery in the Battery Charger is described in more detail in Charging HeartMate Batteries on page 3 81. HeartMate 3 Left Ventricular Assist System Instructions for Use 3 55 3 Powering the System Checking Battery Charge Status Using the On Battery Power Gauge After a HeartMate battery is charged, it should be ready for use. Make sure it has finished charging, and then use the on battery power gauge to confirm that the battery is fully charged. When a battery is fully charged, all five bars light up when you press the power gauge button, indicating that the battery is 80?100% charged.

There is only limited antigenic cross reactivity between marburgvirions and ebolavirions antibiotic resistance report ampicillin 250 mg without prescription. One marburgvirus (Marburg virus, species Lake Victoria marburgvirus*) and four dis tinct ebolaviruses (Reston virus, species Reston ebolavirus; Sudan virus, species Sudan ebolavirus; Tai Forest virus, species Tai Forest ebolavirus; and Ebola virus, species Zaire ebolavirus) have been iden tifed. Genomes from viruses of the ffth lineage (Ravn virus) reach 21% nucleotide difference compared to the others. The variation in genomic sequences has been shown to be low among iso lates of individual floviruses:? There seems to be less or even no genetic variability between isolates from different patients of single outbreaks. Biological properties Filoviruses are endemic in Central Africa in an area approximately between the 10th parallel north and south of the Equator as indicated by the locations of known outbreaks, and in the Philippines (Reston virus only). Filoviruses are the only mononegaviruses that cause viral hemorrhagic fevers in primates. The natural reservoirs of floviruses remain to be identifed, but infectious marburgviruses have been isolated from Egyptian rousettes (Rousettus aegyptiacus) and infectious Reston virus has been isolated from domestic pigs (Sus scrofa). The usual transmission pattern seen with large outbreaks of flovirus disease in humans begins with a focus of infection that disseminates to a number of contacts. Secondary and subsequent epi sodes of disease occur following close contact with patients; such infections usually occur in family members or medical personnel. Usage of contaminated syringes and needles is the main source for nosocomial infections. In the laboratory, nonhuman pri mates, mice, guinea pigs, hamsters and domestic pigs have been infected experimentally, but infec tion of rodents requires sequential adaptation. Other related viruses which may be members of the genus Marburgvirus but have not been approved as species None reported. Species demarcation criteria in the genus Members of different species in the genus may be distinguished on the basis of glycoprotein gene sequence differences (? Phylogenetic relationships within the family Phylogenetic relationships are illustrated in Figure 3 on p. Comparative sequence analyses of single genes indicate that floviruses are phylogenetically quite distinct from mem bers of other families of the order Mononegavirales. Derivation of names Ebola: from the Ebola river in Zaire/Democratic Republic of the Congo, where one of the frst registered outbreaks of the disease was thought to have occurred. Marburg: from Marburg an der Lahn, a town in Germany, where the frst known outbreak of flovirus disease occurred. Filoviruses a Compendium of 40 Years of Epidemiological, Clinical, and Laboratory Studies. Proposal for a revised tax onomy of the family Filoviridae: classifcation, names of taxa and viruses, and virus abbreviations. The envelope is derived directly from the host cell plasma membrane by budding and contains two or three transmembrane glycoproteins. These are present as homo oligomers and form spike like projections, 8?12 nm in length, spaced 7?10 nm apart (depending on the genus). One non glycosylated membrane or matrix protein is associated with the inner face of the envelope. Multiploid virions are found, although the vast majority of virions contain a single functional genome. Virions are very sensitive to heat, lipid sol 20,w vents, ionic and non ionic detergents, formaldehyde and oxidizing agents. Genome lengths for all viruses in the subfamily Paramyxovirinae are multiples of 6, which is a requirement for the effcient replication of the members of the subfamily Paramyxovirinae, but does not apply to the members of the subfamily Pneumovirinae. Pneumoviruses encode 9?11 Virus Taxonomy: Ninth Report of the International Committee on Taxonomy of VirusesDaneshGroup. Virion proteins common to all genera include: three nucleocapsid associated proteins, i. The F protein is synthesized within an infected cell as a precursor (F0) that is acti vated following cleavage by cellular protease(s) to produce the virion disulfde linked F1 and F2 subunits (order: amino F2 S S F1 carboxyl). A protein kinase is associated with many members but it is probably of cellular origin. Fusion and attachment proteins are glycosylated by N linked carbohydrate side chains. In the subfamily Pneumovirinae the attachment protein (G) is heavily glycosylated by O linked as well as N linked carbohydrate side chains. Genome organization and replication the genome organization is illustrated in Figure 2 for viruses representing the seven genera of the family. After attachment to cell receptors, virus entry is achieved by fusion of the virus envelope with the cell surface membrane. Virus replication occurs in the cell cyto plasm and is thought to be independent of host nuclear functions. Transcription is guided by short (10?13 nt) conserved transcription start and termination/ polyadenylation signals fanking each transcriptional element. Intergenic regions are either highly conserved in sequence and length (Respirovirus, Henipavirus, Morbillivirus and all of the newly discovered viruses in the unassigned group; Figure 2 and list on p. Nucleocapsids are enveloped by budding at the cell surface plasma membrane at sites containing virus envelope proteins. Members of the subfamily Paramyxovirinae contain 6?7 transcriptional ele ments that encode 7?11 proteins. Other truncated, or chimeric, proteins (called I, W, or D, depending on the virus) can be produced by shifting into the third reading frame. Antibodies to N and, variably, to other viral proteins also are induced by infection. Various proteins of members of the subfamily Paramyxovirinae have been reported to be broken into specifc peptides that, when complexed to major histocompatibility glycoproteins, serve as recognition molecules for cytotoxic or helper T cells. Biological properties Paramyxoviruses have been conclusively identifed only in vertebrates and mostly in mammals and birds, although they have recently also been detected in reptiles and fsh. Most viruses have a nar row host range in nature, but in cultured cells they display a broad host range. Infection of cultured cells generally is lytic, but temperate or persistent infections in vitro are common. Other features of infection include the formation of inclusion bodies and syncytia. Viruses were selected from the seven established genera as well as a group of unassigned viruses, which signifcantly increased the genetic diversity of the fam ily. The lengths of the boxes are approximately to scale although the intervening or preceding sequences are not to scale. There are conserved trinucleotides that serve as intergenic sequences for the respiroviruses, henipaviruses and morbilliviruses. For rubulaviruses, avulaviruses, pneumoviruses and meta pneumoviruses, the intergenic sequences are variable (1?190 nt long). In the group of unassigned new viruses, all of them have a 3 nt intergenic region similar to those observed in the genera Morbillivirus, Respirovirus and Henipavirus. However, the genome sizes of these new viruses vary signifcantly from 15,378 nt to 19,212 nt. Nucleocapsids associate with viral membrane proteins at the plasma membrane and are enveloped by budding. Paramyxovirus infection typically begins in the respiratory tract and may remain at that site. In general, paramyxovirus infections are limited by, and eliminated by, host immunity. However, virus sometimes can be shed for periods of weeks or months in nor mal and, especially, immunocompromised individuals. The recurrence of neurological manifestations has also been noted in NiV patients more than 4 years after recovery from acute encephalitis. Amino acid sequence relatedness is much greater within the subfamily than between subfamilies. The division of this subfamily into the fve genera is consistent with phylogenetic grouping based on amino acid sequence relation ships. The genome length must be a multiple of 6 nt for effcient genome replication (the rule of six?), perhaps refecting the precise packing of nt by a nucleocapsid pro tein subunit.
