Aquatic ecosystem is the major habitat of toxigenic V. cholerae, where it interacts with various abiotic and biotic factors to survive.

People affected by diarrheal diseases have the lowest financial resources and poorest hygienic facilities.

متن کاملChemotaxis in Vibrio cholerae.
The ability of motile bacteria to swim toward or away from specific environmental stimuli, such as nutrients, oxygen, or light provides cells with a survival advantage, especially under nutrient-limiting conditions. This behavior, called chemotaxis, is mediated by the bacteria changing direction by briefly reversing the direction of rotation of the flagellar motors. A sophisticated signal trans...
متن کاملVibrio cholerae in New Zealand
Toxigenic strains of Vibrio cholerae, although not endemic in New Zealand, are isolated occasionally from recent overseas travellers. Isolates should be confirmed biochemically and serologically and the presence of cholera toxin genes established by a reference laboratory, as non-toxigenic strains are found here in the summer months. Serotypes O1 and O139 are the causative agents of epidemic ch...
