Abstract

Vibrio cholerae, a Gram-negative, motile, aquatic bacterium, is the causal agent of the diarrheal disease cholera. Cholera is a serious epidemic disease that has killed millions of people and continues to be a major health problem world-wide. The hypothesis that V. cholerae occupies an ecological niche in the estuarine environment requires that this organism is able to survive the dynamics of physiochemical stresses, including nutrient starvation. As a result of these stresses, bacteria in nature often exist in non-growth or very slow growth states with a low metabolic activity. Because microorganisms have little ability to control their environment, environmental changes have led to changes in cell function and structure. Such cellular responses can originate in one of two ways: by changes in genetic constitution or by phenotypic adaptation. In this review, we will focus on the phenotypic responses of V. cholerae of a given genotype to starvation stress.
