Toxin production by Vibrio mimicus strains isolated from human and environmental sources in Bangladesh.
Vibrio mimicus has recently been isolated from aquatic environments of Bangladesh. A total of 125 of 300 environmental isolates, representing various biotypes, and 19 human isolates were tested for enteropathogenicity by using several models. Less than 1% of the environmental isolates and slightly more than 10% of the clinical isolates produced cholera toxin-like toxin. A significant percentage...
متن کاملProduction of cholera toxin-like toxin by Vibrio mimicus and non-O1 Vibrio cholerae: batch culture conditions for optimum yields and isolation of hypertoxigenic lincomycin-resistant mutants.
Vibrio mimicus 61892, isolated in 1977 from a case of watery diarrhea in Bangladesh, produces an enterotoxin which possesses activity in Y-1 mouse adrenal cells and in rabbit ileal loops which is identical to the prototype cholera toxin (CT) produced by Vibrio cholerae 569B. The neutralization of the adrenal cell activity of 61892 toxin and 569B CT by homologous and heterologous antisera genera...
متن کاملEnterotoxin production by Vibrio cholerae and Vibrio mimicus grown in continuous culture with microbial cell recycle.
We have examined the effect of complete cell recycle on the production of cholera toxin (CT) by Vibrio cholerae and CT-like toxin by Vibrio mimicus in continuous culture fermentations. Complete cell recycle was obtained by filtering culture fluids through Amicon hollow fibers with an exclusion limit of 100,000 daltons (H1P100-20) and returning the concentrated cell slurry to the fermentor. A si...
متن کاملInteraction between Vibrio mimicus and Acanthamoeba castellanii
Vibrio mimicus is a Gram-negative bacterium, which causes gastroenteritis and is closely related to Vibrio cholerae. The environmental reservoir of this bacterium is far from defined. Acanthamoeba as well as Vibrio species are found in diverse aquatic environments. The present study was aimed to investigate the ability of A. castellanii to host V. mimicus, the role of bacterial protease on inte...
متن کاملCrystal Structure of Arylesterase from Vibrio Mimicus
Introduction: Esterases (E.C. 3.1.1.) are widely distributed in nature and catalyze the hydrolysis of ester bonds. Arylesterases (E.C. 3.1.1.2.) show a preferential substrate specificity for aromatic esters. The mammalian arylesterases play important roles in the detoxification of organophosphorous compounds and are used as diagnostic indicators for liver cirrhosis. Very little is known about t...
