The result of the bacteriological identification of Vibrio cholerae. A) In the oxidase test, the purple color indicates a positive result; B) KIA test, acid/alkaline, no gas, no H2S; C) serologic identification of V. cholerae, showing agglutination for polyvalent O1 antiserum and monovalent Ogawa.

The phylogenetic tree analysis is based on the similarity of the 16S rRNA sequence of the newly isolated Vibrio cholerae to closely related species. The tree was built using MEGA7.0 software, the neighbor-joining method, and bootstrapped 1,000 replicate runs. The newly isolated are shown in bold, and the accession numbers are shown in parentheses after the strain names. The bar indicates substitutions per nucleotide.

Fig. 5.

Box plot showing the number of diagnosed patients admitted to the hospital based on gender; A) comparison between both genders for each month; B) differences between the number of male cases in June and July as well as female cases in June and July. The values’ statistical significance (p-value) is shown above each box. The yellow dot in each box plot represents the mean value, and the horizontal line in each box represents the median value. A p-value < 0.05 is considered significant.
