Culture supernatants from V. cholerae O1 El Tor strains isolated from different geographic areas induce cell vacuolation and cytotoxicity.
OBJECTIVE To investigate whether the HlyA-induced vacuolating effect is produced by V. cholerae O1 ElTor strains isolated from different geographic origins, including Mexico. MATERIAL AND METHODS Supernatant-induced haemolysis, vacuolating activity and cytotoxicity in Vero cells were recorded. PCR, RFLP analysis and molecular cloning were performed. RESULTS All ElTor strains analyzed induce...
متن کاملRapid Screening of Toxigenic Vibrio cholerae O1 Strains from South Iran by PCR-ELISA
Background: The ability to sensitively detect Vibrio cholera with PCR-ELISA method represents a considerable advancement over alternative more time-consuming methods for detection of this pathogen. The aim of this research is to evaluate the suitability of a PCR-enzyme-linked immunosorbent assay for sensitive and rapid detection of V. cholera O1. Methods: The 398-bp sequence of a gene that cod...
متن کاملVibrio cholerae O1 Hybrid El Tor Strains, Asia and Africa
To the Editor: Vibrio cholerae is a water-borne pathogen that causes a severe watery diarrhea disease known as cholera. On the basis of variable somatic O antigen composition, >200 serogroups of V. cholerae have been recognized. Classical and El Tor are 2 well-established biotypes within the V. cholerae O1 serogroup, and they can be distinguished by differences in their biochemical reactions or...
متن کاملTwo different mechanisms of ampicillin resistance operating in strains of Vibrio cholerae O1 independent of resistance genes.
Autoagglutinable strains of Vibrio cholerae O1 (seven nonfimbriate strains and one fimbriate strain) were transformed to obtain resistance to ampicillin. Two distinct mechanisms were found in these strains. One was operating in nonfimbriate strains by reducing OmpU protein production and the other was operating in a fimbriate strain (Bgd17) by newly overproducing cpxP protein. The twitching mot...
متن کامل[Viability of Vibrio cholerae O1 in different types of water under experimental conditions].
The endemic and seasonal nature of cholera depends upon the survival of Vibrio cholerae O1 in a viable but not necessarily culturable state in ecological niches in aquatic environments during inter-epidemic periods, and investigation on the survival of this microorganism in such sites is therefore of the utmost importance. Weekly water aliquots were thus taken from 2 ponds and 2 rivers in the S...
