Figure 1. . Genetic relatedness between Vibrio cholerae genotypes, Bangladesh, 2010–2011. Each genotype is identified by the number of repeats in the allele at the 5 loci VC0147, VC0437, VC1650, VCA0171, and VCA0283. The earliest date of detection is recorded in the box after the fifth allele. The background of the box indicates whether the genotype was detected in clinical isolates only (yellow), environmental isolates only (green), or both (pink). A) Clonal complex of genotypes from Chhatak, Bangladesh, and 5 unrelated genotypes based on a 5-locus genotype. B) Analysis of 3-locus genotypes in Chhatak. C) Five clonal complexes of isolates from Mathbaria, Bangladesh, and 4 unrelated genotypes based on a 5-locus genotype. D) Analysis of 3-locus genotypes from Mathbaria. Env, environmental; clin, clinical.
