Original Prompt

Students will be able to identify the bacterium responsible for cholera and describe its mode of transmission. Students will be able to explain the key symptoms of cholera and the physiological impacts it has on the human body.

This document explores Vibrio cholerae, a Gram-negative bacterium and the causative agent of cholera, which is transmitted primarily through the fecal-oral route via contaminated water or food. It describes the bacterium's natural habitat in aquatic ecosystems and its association with crustaceans. Upon ingestion, Vibrio cholerae colonizes the small intestine, releasing a potent enterotoxin that disrupts salt and water regulation, resulting in severe dehydration, which can be fatal. The resource delves into the transmission cycle, emphasizing the link between environmental factors, bacterial biology, and human health, along with inquiries to enhance understanding of cholera's physiological impacts and interventions to disrupt its transmission.
