Figure 1: UPGMA dendrogram showing PFGE patterns of NotI digested genomic DNA of clinical and environmental V. cholerae isolates. Similarity between isolates was calculated with Dice coefficient and clustering was performed by UPGMA. Each pulsotype has been shown in relation to the source and province of isolation and the presence of virulence associated gene clusters; CP: Clinical Pulsotype, EP: Environmental Pulsotype, C: Clinical, E: Environmental, 1: Tehran, 2: Qom, 3: Zahedan, 4: Golestan. All of the isolates with the same pulsotype showed uniform PCR profi le
