Carriers of equine infectious anemia virus
Journal of the American Veterinary Medical Association, 1984Summary Presently available data continue to support the idea that once a horse is infected with equine infectious anemia virus it remains infected indefinitely. Infection may not always be demonstrated by inoculation of plasma, serum, or whole blood transfusions into susceptible recipients, but transfusions of fresh whole blood will be infective in at

Structural proteins of equine infectious anemia virus
Journal of Virology, 1978Equine infectious anemia virus was found to be comprised of fourteen polypeptides of molecular weight ranging from 10,000 to 79,000. Eighty percent of the virion protein was accounted for by five polypeptides, including two non-glycosylated components (p29 and p13) comprising one-half of the virion protein and three glycoproteins (gp77/79, gp64, and ...

Purification and characterization of equine infectious anemia virus
Archives of Virology, 1976EIA virus was purified from equine fetal kidney cell cultures by PEG-precipitation, two sucrose-gradient sedimentations (5-30 per cent) and (25 to 60 per cent) centrifugation, using the immunodiffusion test to follow the procedure. Purified EIA virus had a density (20 degrees C) of 1.162 and a sedimentation constant of S20w=656.

Characterization of the infection of equine fibroblasts by equine infectious anemia virus
Archives of Virology, 1979Equine dermal fibroblasts persistently infected with equine infectious anemia virus (EIAV) show no alterations in cell morphology or growth kinetics when compared to uninfected cells. The percentage of cells immunofluorescent positive for viral proteins fluctuated, depending upon the stage of the cell cycle, while production of extracellular virus was ...

Transmission of Equine Infectious Anemia Virus by Tabanus fuscicostatus
Journal of the American Veterinary Medical Association, 1976SUMMARY The mechanical transmission of equine infectious anemia (eia) virus by Tabanus fuscicostatus was investigated. In 1 of 7 transmission trials, a single horsefly transmitted eia virus from an acutely infected pony to a susceptible pony. Groups of horseflies isolated for 3, 10, or 30 minutes before refeeding transmitted eia virus, whereas those ...

Hemagglutination by several strains of equine infectious anemia virus
Archives of Virology, 1981Six strains of equine infectious anemia (EIA) virus propagated in equine leukocyte cultures were found to agglutinate horse erythrocytes. Concentrated virus material containing about 20 units of complement fixation (CF) titer showed hemagglutinating (HA) titers ranging from 4 to 8 units.

Studies on equine infectious anemia virus transmission by insects
Journal of the American Veterinary Medical Association, 1984Summary There are several factors involved in the mechanical transmission of equine infectious anemia (eia) virus by insects. Large hematophagous insects, especially tabanids, which feed from extravascular sites (ie, pool feeding) appear to be the most efficient vectors.

Inactivation of Equine Infectious Anemia Virus by Chemical Disinfectants
American Journal of Veterinary Research, 1977SUMMARY Twelve chemicals and commercial disinfectants were tested for inactivation of equine infectious anemia virus. In the presence of 10% bovine serum, all chemicals inactivated 4 log10 (based on 0.1 ml) of the virus within 5 minutes at 23 C. A reduction of at least 4 log10 was observed when the virus was exposed for 1 minute to substituted phenolic

Structure of the Equine Infectious Anemia Virus Tat Protein
Science, 1994Trans-activator (Tat) proteins regulate the transcription of lentiviral DNA in the host cell genome. These RNA binding proteins participate in the life cycle of all known lentiviruses, such as the human immunodeficiency viruses (HIV) or the equine infectious anemia virus (EIAV).

Serologic Survey for Equine Infectious Anemia Virus in Louisiana
Journal of the American Veterinary Medical Association, 1979SUMMARY In 1975, a survey was conducted in East Baton Rouge Parish, Louisiana, to determine the prevalence of equine infectious anemia. Using the agar gel immunodiffusion test, 94 of 1,398 horses (6.7%) were found to be infected. Infection rates were especially high in areas where clinical cases of equine infectious anemia had been diagnosed.
