The 7th pandemic V. cholerae phylogenetic tree depicting the genetic relatedness and position of Tanzanian isolates among selected other sequenced V. cholerae isolates (Additional file 1: Table S1). The phylogenetic tree was constructed on an alignment of the variable sites of 445 strains with predicted recombination sites removed consistent with previous publications [15]. The location and date of collection of selected isolates is noted
