Non-O1/Non-O139 Vibrio cholerae Carrying Multiple Virulence Factors and V. cholerae O1 in the Chesapeake Bay, Maryland

Vibrio cholerae non - O 1 / non - O 139 carrying multiple virulence factors and V . cholerae O 1 in the Chesapeake Bay , Maryland Running title : Pathogenic V . cholerae in the Chesapeake Bay

Virulence factors of non-O1 non-O139 Vibrio cholerae isolated in Córdoba, Argentina.

V. cholerae non-O1 non-O139 serogroups isolated from clinical and environmental sources in Córdoba, Argentina, were analyzed for the presence and expression of virulence genes. Most of the strains studied contained the genes toxR and hlyA, but lacked ctxA, zot, ace, tcpA and stn. The culture supernatants were tested for hemolytic and cytotoxic activity. The enterotoxic potential of the strains ...

Newly Isolated Vibrio cholerae Non-O1, Non-O139 Phages

Although cytologic examination of CSF from patients with encephalitis is likely nonspecific, it may provide supportive information of the suspected disease process, and is useful for excluding other conditions, such as neoplasia. Of the 22 patients that were hospitalized at our institution last year with WNV meningoencephalitis, documented by serologic tests and/or reverse transcription-polymer...

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...

Multiple antibiotic resistance profiles of Vibrio cholerae non-O1 and non-O139.

In this study, the patterns of resistance to 10 antibiotics by 730 Vibrio cholerae non-O1 and non-O139 species isolated from both environmental and seafood samples were investigated. Susceptibility to different antimicrobial agents was assessed by the disc diffusion technique. The frequencies of resistance to 10 antimicrobial agents--ampicillin, chloramphenicol, bacitracin, erythromycin, gentam...
