From: Distribution of hepatitis B virus subgenotype F2a in São Paulo, Brazil
The Maximum Clade Credibility (MCC) tree was estimated by a Bayesian analysis of 198 S/POL sequences of hepatitis B virus strains. The posterior probabilities of the key nodes are shown above the respective nodes. The HBV/F2a samples obtained from Sao Paulo (n=19) were analyzed together with other strains from around the world. Brazilian sequences from North Region (green), Northwest Region (blue), Southeast Region (red) and Center West Region (purple) were highlighted in tree. The clusters containing the strains of other HBV genotypes collapsed.
