Comparison of Vibrio cholerae O139 with V. cholerae O1 classical and El Tor biotypes.
Vibrio cholerae O139 is a recently identified non-O1 V. cholerae strain responsible for outbreaks of epidemic cholera in India, Bangladesh, and Thailand in the past 2 years. Other workers have demonstrated the presence of the cholera toxin genetic element in V. cholerae O139, unlike the situation for other non-O1 V. cholerae strains. We sought to compare further this strain with strains of V. c...
متن کاملGenetic Diversity of ctxB Gene Among Classical O1 and El Tor Strains of Vibrio cholerae using High-Resolution Melting Curve Analysis
Background & Objective: Vibrio cholerae is a natural inhabitant of the environment and causes severe diarrhea ailments (cholera) that affects thousands of people each year worldwide. The most important virulence factors of this pathogen are cholera toxin (cholera toxin CT) and Type IV...
متن کاملDifferences in gene expression between the classical and El Tor biotypes of Vibrio cholerae O1.
Differences in whole-genome expression patterns between the classical and El Tor biotypes of Vibrio cholerae O1 were determined under conditions that induce virulence gene expression in the classical biotype. A total of 524 genes (13.5% of the genome) were found to be differentially expressed in the two biotypes. The expression of genes encoding proteins required for biofilm formation, chemotax...
متن کاملCholera toxin production by the El Tor variant of Vibrio cholerae O1 compared to prototype El Tor and classical biotypes.
Vibrio cholerae O1 El Tor variant strains produced much more cholera toxin than did prototype El Tor strains. The amount of cholera toxin produced by El Tor variant strains both in vitro and in vivo was more or less equivalent to that produced by classical strains.
