the "pressure pan" evolution of human erythrovirus b19 in the amazon, understand the evolutionary dynamics of human parvovirus b19, we analyzed vp1 and vp2 gene sequences of b19 sampled from belém (amazon), the city of são paulo, brazil and globally. our analysis revealed a strikingly different pattern of evolutionary change for those viral lineages introduced into belém, which exhibited a higher rate of nonsynonymous substitutions compared to those viruses sampled from other locations. we propose that difference this is due to the high prevalence of b19 in bel ...200717698162

phylogenetic analysis of a near-full-length sequence of an erythrovirus genotype 3 strain isolated in brazil.human parvovirus b19 is the only member of the genus erythrovirus that causes human disease. recent findings of several strains with considerable sequence divergence from b19 have suggested a new classification for parvovirus genotypes as 1 (b19), 2 (a-6 and lali) and 3 (v9). in their overall dna sequence, the three genotypes differ by approximately 10%. here, we report the isolation of a genotype-3-related strain named br543 during a prospective study conducted in sao paulo, brazil. analysis of ...200919701602
