Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. [2] It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. [2] Undercooked shellfish is a common source. [9] Humans are the only known host for the bacteria. [2]
[37] [41] Worldwide, diarrhoeal disease, caused by cholera and many other pathogens, is the second-leading cause of death for children under the age of 5 and at least 120,000 deaths are estimated to be caused by cholera each year. [42] [43] In 2002, the WHO deemed that the case fatality ratio for cholera was about 3.95%. [37]
Cholera primarily presents with rapid water loss by watery diarrhea. Other symptoms include vomiting and muscle cramps. [25] Water loss can lead to dehydration which can be mild to moderate to severe. Moderate to severe dehydration requires immediate treatment. V. cholerae is the most common pathogen that causes cholera. The gold standard for ...
Koch's postulation was proven correct by Indian microbiologist Sambhu Nath De, who in 1951 studied and documented the effects of injecting rabbits with heat-killed cholera bacteria. [5] He concluded from this experiment that an endotoxin liberated upon disintegration of the bacteria was the cause of the symptoms of cholera. [5]
Recent discoveries may eventually help researchers prevent cholera bacteria from causing deadly illness, according to a report published in Nature Communications. ... The genes are linked to the ...
Vibrio cholerae bacteria are transmitted through contaminated water. [10] Once ingested, the bacteria colonize the intestinal tract of the host and produce a toxin which causes body fluids to flow across the lining of the intestine. Death can result in 2–3 hours from dehydration if no treatment is provided. [11]
Cholera (caused by Vibrio cholerae bacteria) and bubonic plague, or the Black Death (caused by the bacterium Yersinia pestis) are some of the most famous examples of how devastating a pandemic can be.
