Passage of Vibrio cholerae through the human body results in reduced infectivity for the next human host.

Question

Quizplus · Accepted Answer

Passage through the human body actually enhances the infectivity of Vibrio cholerae for the next human host. Cholera spreads through fecal-oral route and contaminated water and food. Once ingested, the bacteria colonize in the small intestine and produce cholera toxin which causes profuse watery diarrhea. The excreted bacteria along with the contaminated feces go into the environment and can infect another person who ingests it. Therefore, passage through the human body increases the pathogen's survival and transmission ability.
