Abstract excerpt
Three genotypes (1-3) of human parvovirus B19 have been identified. Analysis of 13 nearly full-length genotype 3 sequences from Ghana, Europe and Brazil identified two genetically distinct clusters. The classification of genotype 3 strains into two subtypes (B19/3a and B19/3b) is proposed. The rate of evolutionary change of B19 genotype 3 strains (2 x 10(-4) nucleotide substitutions per site per year) was similar...
