Phylogenetic Analysis of the p24-p7 Region of the Human Immunodeficiency Virus Type 1 gag Gene To Determine Subtype Distribution among Female Sex Workers in Calcutta India

摘要

Human immunodeficiency virus type 1 (HIV-1) subtype C, based on the envelope region, has been reported to be predominant in India. We sequenced the p24-p7 gag region from 51 HIV-1 seropositive female sex workers in Calcutta, India, for more-detailed molecular characterization. Subtype C was found to be prevalent, although no strong monophyletic cluster was observed.
