CRF22_01A1 is involved in the emergence of new HIV-1 recombinants in Cameroon.

ABSTRACT: Cameroon is a West African country where high genetic diversity of HIV-1 has been reported. The predominant CRF02_AG is involved in the emergence of more complex intersubtype recombinants. In this study, we sequenced the full-length genome of a novel unique recombinant form of HIV-1, 02CAMLT04 isolated in blood donors in urban Cameroon. Phylogenetic tree and bootscan analysis showed that 02CAMLT04 was complex and seemed to be a secondary recombinant derived from CRF02_AG and CRF22_01A1. The genomic composition of 02CAMLT04 strain showed that it is composed of 3 segments; 24% of the genome is classified as CRF02_AG, spanning most of the envelope gene. The remaining 76% of the genome is classified as CRF22_01A1. In addition, the sequence analysis of 13 full-length sequences from HIV-1-positi
