Hepatitis B virus subgenotype A1: evolutionary relationships between Brazilian, African and Asian isolates.

PloS one - 1 Jan 2014

Lago Bárbara V, Mello Francisco C, Kramvis Anna, Niel Christian, Gomes Selma A

Abstract excerpt

Brazil is a country of low hepatitis B virus (HBV) endemicity in which the genotype A of HBV (HBV/A) is the most prevalent. The complete nucleotide sequences of 26 HBV/A isolates, originating from eight Brazilian states, were determined. All were adw2. Twenty-three belonged to subgenotype A1 and three to A2. By phylogenetic analysis, it was shown that all the 23 HBV/A1 isolates clustered together with isolates...
