From: Detection of Hepatitis B virus subgenotype A1 in a Quilombo community from Maranhão, Brazil
The maximum clade credibility (MCC) tree was estimated by Bayesian analysis of 320 S/POL sequences with 1306 bp of Hepatitis B virus strains. The posterior probabilities of the key nodes (internal nodes) are depicted above the respective nodes. Samples HBV/A1 obtained from Frechal (n = 4, red taxa) were analyzed together with other worldwide strains by Maximum Likelihood (ML) method (n = 134). The clusters containing the strains of others Afro-Brazilian communities previously reported are highlighted (Blue taxes). Genotype B (n = 19), genotype C (n = 20), genotype D (n = 24), genotype E (n = 7), genotype F (n = 25), genotype G (n = 4), genotype H (n = 6) and genotype I (n = 9) branches were collapsed. Also, the subgenotypes A2 (n = 52), A3, A4, and A5 (n = 10), A6 (n = 3) and A7 (n = 7) branches were collapsed.
