Phylogram of genetic relationship between VP1 nucleotide sequences of CV-B3 isolates. The phylogenetic tree is based on an alignment of the partial VP1 sequences. The CV-B3 sequences recovered in Nigeria in 2002 and the strains newly described in this study are indicated within sub-Saharan Africa (SSA). The strains indicated with black triangl represent CV-B3 strains from Niger; a country in west-Africa that shares a border with Northern-Nigeria
