| genetic characterization of vibrio vulnificus strains isolated from oyster samples in mexico. | vibrio vulnificus strains were isolated from oysters that were collected at the main seafood market in mexico city. strains were characterized with regard to vvha, vcg genotype, pfge, multilocus sequence typing (mlst), and rtxa1. analyses included a comparison with rtxa1 reference sequences. environmental (vcge) and clinical (vcgc) genotypes were isolated at nearly equal percentages. pfge had high heterogeneity, but the strains clustered by vcge or vcgc genotype. select housekeeping genes for ml ... | 2015 | 25651067 |
| 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 |
