Enterotoxicity of bacteria-free culture filtrate of Vibrio cholerae. Cholera is an infection of the small intestine caused by the bacterium "Vibrio cholerae". This is a timeline of cholera, a disease caused by the bacterium "Vibrio cholerae". These were caused by enterotoxin-producing strains of the bacterium "Vibrio cholerae". Vibrio cholera bacteria are transmitted through contaminated water. Alkalotolerant marine bacteria such as "Pseudomonas" and "Vibrio" spp. "S. rosetta" is induced to undergo sexual reproduction by the marine bacterium "Vibrio fischeri". Bacterial bioluminescence is seen in Photobacterium species, "Vibrio fischeri, Vibrio haweyi, and Vibrio harveyi". Microbial collagenases have been identified from bacteria of both the "Vibrio" and "Clostridium" genera. In addition, nanocellulose is not acutely toxic to Vibrio fischeri in environmentally relevant concentrations. Collagen cleavage occurs at an in "Vibrio" bacteria and at bonds in "Clostridium" collagenases. Many have even been identified to genus&colon; Persicirhabdus, Fluviicola, Synecococcus, Vibrio, and Enterococcus. Many "Vibrio" species are also zoonotic. Several species of "Vibrio" are pathogens. The most common is vibriosis, caused by bacteria of the "Vibrio" species.
