چکیده انگلیسی
Molecular analysis of the regulatory and structurally important genetic segments of equine infectious anemia virus (EIAV) in mules is presented. We have previously reported clinicopathological and laboratory findings in mules infected with EIAV, both naturally and after experimental inoculation. In this study the fragment coding for integrase, gp90, tat and the fusion domain of gp45 of the proviral genome from these animals was sequenced and compared with one another and with that of EIAV strains already published in the literature. Significant variations were observed mainly in the sequences of the gp90 surface protein. In the two wild type sequences, there were substitutions in the V5 hypervariable domain of this protein. In the sequences of the experimentally inoculated animals and the donor strain, variations were due to insertions/duplications in the V3 principal neutralizing domain (PND) and substitutions in the V5 hypervariable domain. Finally, when compared with the already published strains, the wild type sequences had single amino acid substitutions across the whole protein and multiple substitutions in the V4-V6 variable domains. In general, the two Greek wild type sequences were closer to two of the American strains (WSU5 and Massachusetts), than to the two Japanese (V26 and V70) or the third American strain (Wyoming_wi) used in this study.
