Reviewing the History of HIV-1: Spread of Subtype B in the Americas
Figure 3
Part of the Bayesian tree of 263 HIV-1 subtype B sequences of the pol gene (Pandemic Clade C).
Part of the 50% majority rule consensus tree constructed from the Bayesian MCMC (BEAST) analysis. This is the full version of the collapsed group shown in Figure 1, indicating the evolutionary relationships among the sequences in the pandemic clade. The orange branches represent the isolates from the Caribbean, purple branches represent isolates from Central America, the green branches represent the South American isolates, and the blue branches represent the isolates from North America. The branches are not drawn to scale. Abbreviations of countries are as follows: AR, Argentina; AG, Antigua and Barbuda; BH, Bahamas; BR, Brazil; BW, Botswana; CA, Canada; CD, Democratic Congo; CM, Cameroon; CO, Colombia; CU, Cuba; DO, Dominican Republic; EC, Ecuador; ET, Ethiopia; GD, Grenada; GY, Guyana; HT, Haiti; JM, Jamaica; LC, Santa Lucia; SR, Suriname; TT, Trinidad and Tobago; TZ, Tanzania; UG, Uganda; US, United States; VC, St Vincent; VE, Venezuela.
