3. DLA-EIAV can be served as the animal model for studying on human immunodeficiency virus. The vaccine was developed in two stages. A carefully selected field isolate, EIAV LN, was passaged 133 times in vivo in donkeys to generate the highly virulent and pathogenic strain D510, which kills animals within a few weeks. D510 went through 135 passages in vitro to obtain vaccine strains DLV. In order to investigate the molecular mechanism of the attenuation and protection of donkey leukocyte attenuated equine infectious anemia virus, we investigated the evolution of LTR of 24 out of 110 passages during Chinese EIAV attenuation.
