Phylogenetic analyses of Texas isolates indicate an evolving subtype of the clade B feline immunodeficiency viruses

J Virol. 2004 Feb;78(4):2158-63. doi: 10.1128/jvi.78.4.2158-2163.2004.

Abstract

Rigorous phylogenetic analyses were used to compare the nucleotide sequences of feline immunodeficiency virus strains isolated from Texas and throughout the world. The envelope V3-V4 sequences and capsid gene of the Texas isolates formed a cluster between subtypes B and E. Statistical comparisons with other published sequences confirmed that the Texas group is a unique cluster, possibly a new subtype, arising from subtype B.
