| outbreak of vibrio cholerae serogroup o1, serotype ogawa, biotype el tor strain--la huasteca region, mexico, 2013. | on september 2 and 6, 2013, mexico's national system of epidemiological surveillance identified two cases of cholera in mexico city. rectal swab cultures from both patients were confirmed as toxigenic vibrio cholerae serogroup o1, serotype ogawa, biotype el tor. pulsed-field gel electrophoresis and virulence gene amplification (ctxa, ctxb, zot, and ace) demonstrated that the strains were identical to one another but different from strains circulating in mexico previously. the strains were indist ... | 2014 | 24964882 |
| quantification of vibrio species in oysters from the gulf of mexico with two procedures based on mpn and pcr. | oysters can accumulate potentially pathogenic water bacteria. the objective of this study was to compare two procedures to quantify vibrio species present in oysters to determine the most sensitive method. we analyzed oyster samples from the gulf of mexico, commercialized in mexico city. the samples were inoculated in tubes with alkaline peptone water (apw), based on three tubes and four dilutions (10(-1) to 10(-4)). from these tubes, the first quantification of vibrio species was performed (mos ... | 2016 | 27709461 |
| biochemical and full genome sequence analyses of clinical vibrio cholerae isolates in mexico reveals the presence of novel v. cholerae strains. | the first week of september 2013, the national epidemiological surveillance system identified two cases of cholera in mexico city. the cultures of both samples were confirmed as vibrio cholerae serogroup o1, serotype ogawa, biotype el tor. initial analyses by pfge and by pcr-amplification of the virulence genes, suggested that both strains were similar, but different from those previously reported in mexico. the following week, four more cases were identified in a community in the state of hidal ... | 2016 | 26828665 |
