Cholera bacteria. Petri dish containing colonies of Vibrio cholerae bacteria. These water-borne pathogens are the cause of the disease cholera in humans. The bacteria are transmitted to humans in contaminated water and food. The bacteria infect the small intestine and produce a toxin that causes diarrhoea,leading to severe dehydration which may be fatal if untreated. Outbreaks are associated with poor sanitary conditions and are often epidemic. These bacteria have been cultured in a general purpose nutrient medium called tryptic soy agar (TSA) | |
