Association of Heavy Rainfall on Genotypic Diversity in V. cholerae Isolates from an Outbreak in India

Figure 3

Cluster analysis of ERIC-PCR fingerprints of V. cholerae isolates in November 2005. Isolates were grouped into two clusters, Genotype1: VCM1–VCM24; and Genotype2 VCM28–VCM38, that were separated by the date of isolation. V. cholerae O1 (ATCC 14033) and O139 (NICED) were used as references strains.
