Maximum likelihood tree depicting genetic relationships of strains examined in this study utilizing the p72 locus. Bootstrap support (BS) is indicated by * for values between 75% and 85%, and by + for values greater than 85% support. The scale bar indicates the number of nucleotide substitutions per site. Each color is a different genotype, indicated by the corresponding roman numerals. Labels for all strains generated by this study begin with •drc (Democratic Republic of the Congo). Strains are named in the following manner: Country_Strain Name. Acronyms used for countries of origin are as follows: Ang = Angola, Ben = Benin, Bot = Botswana, Bra = Brazil, Bur = Burundi, Cam = Cameroon, CV = Cape Verde, Dom Rep = Dominican Republic, the DRC = Democratic Republic of Congo, IC = Ivory Coast, Ita = Italy, Ken = Kenya, Mad = Madagascar, Mal = Malawi, Malt = Malta, Moz = Mozambique, Nam = Namibia, Nig = Nigeria, Port = Portugal, SA = South Africa, Tan = Tanzania, Ug = Uganda, Zam = Zambia, Zimb = Zimbabwe.
