ABSTRACT:
Bacteria of the genus Vibrio typically habitat marine and estuarine environment and are commonly isolated from fish. The main Vibrio species reported as agents of infections in humans are V. vulnificus , V. parahaemolyticus , V. cholerae and V. mimicus . V. vulnificus is considered the most dangerous, may cause sepsis and lead to death. V. parahaemolyticus is an important pathogen in coastal regions of temperate and tropical climates around the world and has been responsible for cases of gastroenteritis associated with consumption of fish, shellfish and marine crustaceans. V. cholerae causes outbreaks, epidemics and pandemics related to estuarine environments. V. mimicus can cause sporadic episodes of acute gastroenteritis and infections. The pathogenicity of the bacteria is linked to the ability of the micro-organism to initiate a disease (including entry, colonization and multiplication in the human body). For this to occur, the micro-organisms make use of several factors. The objective of this review is to summarize the knowledge available in the literature on the factors of pathogenicity of V. vulnificus , V. parahaemolyticus , V. cholerae and V. mimicus .
