Maximum clade credibility (MCC) phylogenetic tree of pol sequences based on the ID clade. The MCC tree of HIV-1B in the ID clade was estimated by a Bayesian Markov chain Monte Carlo approach. Times to the most recent common ancestors (tMRCAs) for phylogenetic clades of interest are indicated as mean dates and 95% highest posterior density (HPD) regions. The geographic origins of the sequences are represented by colors or two-letter country codes as follows: AR, Argentina; AU, Australia; BR, Brazil; CA, Canada; CH, Switzerland; CN, China; DE, Germany; ES, Spain; FR, France; GB, United Kingdom of Great Britain and Northern Ireland; GL, Greenland; HN, Honduras; ID, Indonesia; IT, Italy; JP, Japan; KR, Korea; MX, Mexico; PA, Panama; PH, Philippines; RS, Serbia; SE, Sweden; SD, Sudan; TH, Thailand; US, the United States of America; ZA, South Africa.
