PG - 3879-82 AB - Equine infectious anemia virus (EIAV) is a lentivirus that infects and persists in the monocyte/macrophage populations of blood and tissues. We employed polymerase chain reaction to investigate the distribution and the level of genome variability of EIAV DNA in different tissues of a horse infected with a highly virulent variant of the Wyoming strain of the virus. Long terminal repeat, gag, and pol primer pairs were used to direct the amplification of EIAV DNA from the peripheral blood mononuclear cells and from cells, presumably the macrophage subtypes, of the kidney, spleen, liver, lymph node, and cerebellum and periventricular regions of the brain. Polymerase chain reaction analysis of four domains within the envelope showed that viral subtypes with particular envelope domains segregated to different tissues as defined by the presence or absence of a given type of domain. Collectively, these results show that virus variants in the env gene home to different tissues, presumably because of selection for tissue-specific envelope determinants.
