The bacterium itself is small, and comma-shaped (see appendix p.7 ). vibrion cholerae is a gram-negative bacteria that is a pathogen of humans. The bacteria moves by means of flagellum. The bacterium produces a toxin that causes the small intestine to secrete fluids, lead story to disgorge and diarrhea. The life cycle of the cholera bacterium is simple; Vibrio cholera reproduces by binary fission, a form of agamous reproduction. The genus, Vibrio, are typically leatherneck organisms that are found on the surface of the water. The cholera bacteria is ordinarily found in the same water as feces. The bacteria, one time ingested by humans, begins to produce a Cholera toxin. Cholera toxin activates special enzymes in intestinal cells, which leads to the secretion of fluids into the small intestine, causing symptoms like diarrhea.

approximately of the bacterium are not able to survive the secretions and initiatory base pH of the stomach; after the release of the Cholera toxin, the bacterium usually die. The first true case of cholera was recorded in Europe in 1830 and again, in 1848, 1854, 1865, 1884, and 1892. During! the wondrous London pestiferous of 1854, John Snow, proved cholera to be a waterborne disease, done epidemiological means.
