| nucleotide sequence of feline immunodeficiency virus: classification of japanese isolates into two subtypes which are distinct from non-japanese subtypes. | seven isolates of feline immunodeficiency virus (fiv), shizuoka, yokohama, sendai-1, sendai-2, fukuoka, aomori-1, and aomori-2, were isolated from fiv-seropositive domestic cats in japan, and their proviral dnas were amplified by pcr. the nucleotide sequences of their env and gag genes were determined and compared with those of previously described isolates: u.s. and european isolates and one japanese isolate, tm2. phylogenetic analyses of complete env gene sequences demonstrate that worldwide i ... | 1995 | 7745712 |
