Phylogenetic confirmation of the presence of two circulating SFV strains among mandrills. Phylogenetic tree of the 425-bp fragments of a region of the integrase region in the SFV polymerase gene. All 11 representative strains newly identified from mandrills in the colony (in red) at the CIRMF and the 8 new strains identified from wild mandrills (in blue) located in various regions of the country are shown in the tree. The new strains from mandrills were analysed with SFV sequences obtained from various species of nonhuman primates available in Genbank. The phylogenetic tree was obtained by the Bayesian method implemented in MrBayes version 3.1 software as described in the legend to Figure 2. The names of the different nonhuman primate species included in the tree are listed on the right side of the tree.
