title: Sequencing and phylogenetic analysis of gp51 gene of bovine leukaemia virus in Iranian isolates.
abstract: Analysis of the partial bovine leukaemia virus (BLV) gp51 gene sequences obtained from five BLV strains isolated in different regions of Iran and BLV-FLK strain was carried out. The Iranian BLV gp51 sequences were compared with seven other corresponding sequences of BLV strains isolated in different countries. Nucleotide sequence analysis showed a variability of 0.003-5.1% and the phylogenetic tree constructed revealed three clusters. The first cluster included French, German and FLK-BLV samples; the second cluster included four Iranian samples; and the third cluster included Australian, Korean, Japanese, Brazilian and Belgian reference strains and one Iranian sample. Iranian samples were had significantly similarity to European and Australian samples.
