Vibrio

Cholerae Vibrio cholerae is a Gram-negative, rod-shaped bacterium that is responsible for the deadly diarrheal disease cholera. Cholera is an infectious disease of the small intestine, caused by the bacterium V. cholerae, and is characterized by watery diarrhoea resulting in severe dehydration. It is spread through contaminated food and water and is a major public health issue in many countries. Cholera can be treated with antibiotics and rapid rehydration therapy, and prevention efforts focus on improved sanitation and availability of safe drinking water. V. cholerae is also studied to understand its virulence factors, providing insight into bacterial pathogenesis.
