 Equine Infectious Anemia Virus (EIAV)

Equine infectious anemia virus (EIAV) is a lentivirus (slow virus) which is very similar to HIV and cause the state of immunodficiency in horse,that hinders its ability to protect itself against other common infections.Like HIV, EIA can be transmitted through blood, saliva, milk, body secretions and also through biting flies, such as the horse-fly and deer-fly. gag and pol are the commonly found gene,genome annotation of EIAV is still under research.
[ A vaccine is available, called "Chinese Live Attenuated EIA vaccine", developed in China and widely used there since 1983. Another attenuated live virus vaccine is in development in the United States]


Like many other lentiviruses, not much studies have been carried out on this virus. However, studies on EIAV is expected to aid to our understanding of HIV viruses .
