Vibrio cholerae non-serogroup O1 cystitis.
We report a case of a patient who developed cystitis caused by non-serogroup O1 Vibrio cholerae after swimming in the Chesapeake Bay. Treatment was empirical, with complete symptomatic resolution. Genitourinary tract infections by Vibrio spp. are uncommon but should be considered when cystitis occurs after saltwater exposure in appropriate geographic regions.
متن کاملIdentity of hemolysins produced by Vibrio cholerae non-O1 and V. cholerae O1, biotype El Tor.
Hemolysins purified from non-O1 Vibrio cholerae (non-O1 hemolysin) and a Vibrio cholerae O1, biotype El Tor (El Tor hemolysin) were investigated for their homology. The hemolysins were isolated from the culture supernatant fluids by ammonium sulfate precipitation and gel filtration on Sephadex G-100 columns. The purified hemolysins gave single bands with an identical mobility on conventional po...
متن کاملComparative genome analysis of non-toxigenic non-O1 versus toxigenic O1 Vibrio cholerae
Pathogenic strains of Vibrio cholerae are responsible for endemic and pandemic outbreaks of the disease cholera. The complete toxigenic mechanisms underlying virulence in Vibrio strains are poorly understood. The hypothesis of this work was that virulent versus non-virulent strains of V. cholerae harbor distinctive genomic elements that encode virulence. The purpose of this study was to elucida...
متن کاملHybrid El Tor Vibrio cholerae O1, Kuwait
To the Editor: The traditional causative agent of cholera, Vibrio chol-erae O1, has 2 biotypes, classical and El Tor. The current seventh pandemic that began in 1961 and has spread to much of the world is caused by the El Tor biotype. This biotype has replaced the classical biotype responsible for the previous pandemics. The classical and El Tor biotypes are differentiated by phenotypic tests (...
متن کاملThe Vibrio cholerae O1 chromosomal integron.
Until the discovery of the Vibrio cholerae repeat (VCR), the gene capture and expression systems termed integrons had been typically associated with antibiotic-resistance gene cassettes with usually less than five genes in an array. A method is described for the cloning of the ends of large cassette arrays. Conserved restriction sites within VCRs facilitated the mapping by Southern hybridizatio...
