Permeability and enterotoxic factors of nonagglutinable vibrios Vibrio alcaligenes and Vibrio parahaemolyticus.

چکیده
Enterotoxic factor (EF) was present and could be developed in nonagglutinable vibrios, but not the permeability factor (PF). Presence of PF without EF in Vibrio parahaemolyticus is significant. Both EF and PF were absent in V. alcaligenes.

متن کاملContribution of Vibrio parahaemolyticus virulence factors to cytotoxicity, enterotoxicity, and lethality in mice.
Vibrio parahaemolyticus, one of the human-pathogenic vibrios, causes three major types of clinical illness: gastroenteritis, wound infections, and septicemia. Thermostable direct hemolysin (TDH) secreted by this bacterium has been considered a major virulence factor of gastroenteritis because it has biological activities, including cytotoxic and enterotoxic activities. Previous reports revealed...

Introduction: Using zinc oxide nanoparticles, as a catalyst removal of fecal pollution indicator bacteria in water, has been studied as a model of bacterial contamination. This study aims to determine the toxicity and selection of appropriate indicators to evaluate the toxicity of zinc oxide nanoparticles on the isolated bacteria Vibrio species of Bushehr coastal waters. Methods: In this experi...
متن کاملEnvironmental vibrios represent a source of antagonistic compounds that inhibit pathogenic Vibrio cholerae and Vibrio parahaemolyticus strains
With the overuse of antibiotics, many pathogens including Vibrio cholerae and Vibrio parahaemolyticus have evolved multidrug resistance making treatment more difficult. While understanding the mechanisms that underlie pathogenesis is crucial, knowledge of bacterial interactions of V. cholerae and V. parahaemolyticus could provide insight to their susceptibility outside of the human host. Based ...
