Molecular characterization of Vibrio cholerae outbreak strains with altered El Tor biotype from southern India
Forty-four Vibrio cholerae isolates collected over a 7-month period in Chennai, India in 2004 were characterized for gene traits, antimicrobial susceptibility and genomic fingerprints. All 44 isolates were identified as O1 El Tor Ogawa, positive for various toxigenic and pathogenic genes viz. ace, ctxB, hlyA, ompU, ompW, rfbO1, rtx, tcpA, toxR and zot. Nucleotide sequencing revealed the presenc...
متن کاملMolecular characterization of serogrouping and virulence genes of Malaysian Vibrio cholerae isolated from different sources.
A pair of primers targeting the hlyA gene for Vibrio cholerae which could distinguish the classical from El Tor biotypes was designed and combined with other specific primers for ompW, rfb complex, and virulence genes such as ctxA, toxR, and tcpI in a multiplex PCR (m-PCR) assay. This m-PCR correctly identified 39 V. cholerae from clinical, water and seafood samples. The efficiency of this mult...
متن کاملCharacterization of Vibrio cholerae isolated from oysters.
Of 790 samples of oyster shellstock freshly harvested during a 12-month survey, 111 (most of which were harvested from June through August) contained Vibrio cholerae non-O1 (611 strains), and seven contained O1 Inaba (11 strains) organisms. None of the V. cholerae strains isolated were enterotoxigenic by immunological and biological tests.
متن کاملmolecular characterization of vibrio cholerae isolated from clinical samples in kurdistan province, iran
conclusions polymerase chain reaction has specificity and accuracy for identification of the organism and is able to differentiate biotypes. enterobacterial repetitive intergenic consensus sequence is one of the informative and discriminative methods for the analysis of v. cholerae diversity. the rep-pcr is a less informative and discriminative method compared to other methods for the analysis ...
متن کاملCharacterization and Genetic Variation of Vibrio cholerae Isolated from Clinical and Environmental Sources in Thailand
Cholera is still an important public health problem in several countries, including Thailand. In this study, a collection of clinical and environmental V. cholerae serogroup O1, O139, and non-O1/non-O139 strains originating from Thailand (1983 to 2013) was characterized to determine phenotypic and genotypic traits and to investigate the genetic relatedness. Using a combination of conventional m...
