From: Natural transmission of feline immunodeficiency virus from infected queen to kitten
Neighbour-joining phylogenetic tree based on alignment of 362 nucleotides (nt) from CA- gag region. Bootstrap values based on 1000 replicates. Values greater than 70% are shown. Brazilian samples are represented by grey branch lines, and samples from the study are represented by a gray box and symbols: the black circle represents sequences from the queen (RJ48); the white circle, those from the kitten (RJ36); the gray lozenge, those from the female cat (RJ47); the black square, those from tomcat 1 (RJ34); and the white square, those from tomcat 2 (RJ35). The horizontal bar indicates the nucleotide substitution scale. Reference sequences from GenBank are: Subtype A - From USA: Petaluma (M25381), PPR (M36968). Subtype B - From Japan: TM2 (M59418), Yokohama (D37819). From USA: USIL2489 (U11820). From Brazil: RJ01 to RJ08 (EU375620 to EU375627); RJ10 and RJ11 (EU375629 and EU375630); RJ13 to RJ24 (EU375632 to EU375643); RJ34 and RJ35 (EU375644 and EU375645). Subtype C – From USA: C36 (AY600517). From Canada: C (AF474246). Subtype E – From Argentina: LP3 (AB027302), LP20 (AB027303), LP24 (AB027304). Subtype D – From Japan: Fukuoka (D37822), Shizuoka (D37818). Selvage isolate from Pallas cat (AY713445).
