Sequencing and phylogenetic analysis of Bovine Immunodeficiency Virus env gene in Iran

Bovine Immunodeficiency Virus (BIV) belongs to the genus Lentivirus of the family Retroviridae comprising 3 main structural genes of gag, pol and env. For determination of genetic relationship of env gene of BIV in Iran with those in other countries firstly fragments 490 bp corresponding to env from 5 samples amplified in PCR system and was sequenced for determining nucleotide sequence and was compared with identified nucleotide sequence of this gene in other countries
