Detailed explanation-1: -The cholera bacterium is usually found in water or in foods that have been contaminated by feces (poop) from a person infected with cholera bacteria. Cholera is most likely to occur and spread in places with inadequate water treatment, poor sanitation, and inadequate hygiene.

Detailed explanation-2: -V. cholerae can grow between pH 6.5 and 9, but its preferred pH is that of seawater, at ∼8 (74). Acidic pH regulates the expression of virulence factors in V. cholerae.

Detailed explanation-3: -cholerae cells are very sensitive to the low pH of the stomach, and the dose required to cause infection in healthy volunteers, 1011 cells, is perhaps unrealistically high [11].
