Abstract excerpt

BACKGROUND: Recent studies suggest HIV-1 inter-subtype differences in co-receptor usage. We examined the correlation between HIV-1 subtype and co-receptor usage among treatment-naïve HIV-1 subjects in Singapore. Additionally, we investigated whether the subtype co-receptor association was influenced by stage of infection. METHODS: V3 sequences of HIV-1 envelope protein gp120 were obtained from 110 HIV...
