The pathogenicity ofV. choleraeis mediated by the virulence factors CT and TCP which are long filamentous pili that help in the attachment and colonization of bacterial cell...
V. choleraeis faced with growth inhibitory substances such asbile saltsand defense factors, e.g. complement anddefensins, against which it has developed survival strategies. In the course of cholera pathogenesis,V. choleraeexpresses atranscriptional activatorToxT, which subsequently transactivates ...

We speculated that the seemingly collapsed CV membranes might have been due to amoebal membrane rupture caused by thehapA-minus mutant strain. Given that bacterial pathogens often cause membrane rupture through the secretion of PFTs33, we wondered whether the secreted hemolysin ofV. cholerae(HlyA) ...

on thiosulphate citrate bile salts sucrose agar (TCBS) and confirmation of strain identity was done by serology using polyvalent, anti-Ogawa, and anti-Inaba antisera (Denka Seiken, Tokyo, Japan). Haemolysis test was done by growingV. choleraeon 5% sheep blood nutrient agar plates incubated at ...
on the fish blood agar plate and egg yolk plates respectively,and the activities of haemolytic and phospholipase were determined by the appearance of a lytic zone and opalescence around the bacterial growth.It was found that all the vibrios strains with TLH haemolysin gene had haemolytic ...
cholerae, V. parahaemolyticus and V. alginolyticus grow at 42°C. Vibrios have a low tolerance to acid and prefer alkaline conditions (growth range pH 6.8–10.2, optimum pH 7.4–9.6). Vibrio cholerae Description Strains of V. cholerae can be differentiated by their lipopolysaccharide O-antigens...
As otherVibriospecies,V. choleraeis part of the autochthonousbacterial floraof estuarine areas, and its growth may occur in variable temperature conditions (from 10 to 43°C) and in NaCl concentrations ranging from 0.1% to 4.0%. Halotolerance ofV. choleraeis a key feature of its transmission,...
