In vitro isolation of a neutralization escape mutant of equine infectious anemia virus (EIAV).
A neutralization escape mutant (A/1 E) of equine infectious anemia virus was isolated after 13 passages in cell culture in the presence of serum containing antibodies to type- and group-specific determinants of EIAV envelope glycoproteins. Loss of neutralization by the selecting serum correlated with loss of two epitopes in the major envelope glycoprotein gp90 of A/1 E which were present in a parallel variant isolated from a persistently infected pony.
