MCC phylogenetic tree of gag sequences based on ID and US clades. The MCC tree of HIV-1B of the gag region in the ID and US clades was estimated by a Bayesian MCMC approach. HIV-1 subtype C sequences were used as the outgroup in the rooted tree. tMRCAs for phylogenetic clusters of interest are indicated as mean dates and 95% HPD regions. The geographic origins of the sequences are represented by colors or two-letter country codes as follows: AU, Australia; BR, Brazil; DE, Germany; DK, Denmark; ET, Ethiopia; ES, Spain; FR, France; GB, United Kingdom of Great Britain and Northern Ireland; ID, Indonesia; IN, India; KR, Korea; NL, Netherlands; UA, Ukraine; US, the United States of America; ZA, South Africa.
