| evaluation of a rapd-based typing scheme in a molecular epidemiology study of vibrio cholerae o1, brazil. | to evaluate the utility of random amplification of polymorphic dna (rapd) technique for routine practice in public health laboratories for epidemiological studies of vibrio cholerae o1 isolates. | 2004 | 14962124 |
| occurrence and composition of class 1 and class 2 integrons in clinical and environmental o1 and non-o1/non-o139 vibrio cholerae strains from the brazilian amazon. | this study identified and characterised class 1 and 2 integrons in clinical and environmental vibrio cholerae o1 and non-o1/non-o139 strains isolated from the brazilian amazon. the aada2 and aada7 gene cassettes were found in class 1 integrons in two genotypes of environmental v. cholerae non-o1/non-o139. empty integrons were found in strains from the brazilian cholera epidemic. a class 2 integron was detected in one strain from the v. cholerae amazonia lineage harbouring sat1 and aada1 genes. a ... | 2010 | 20428687 |
| population and genetic study of vibrio cholerae from the amazon environment confirms that the wasa-1 prophage is the main marker of the epidemic strain that circulated in the region. | vibrio cholerae is a natural inhabitant of many aquatic environments in the world. biotypes harboring similar virulence-related gene clusters are the causative agents of epidemic cholera, but the majority of strains are harmless to humans. since 1971, environmental surveillance for potentially pathogenic v. cholerae has resulted in the isolation of many strains from the brazilian amazon aquatic ecosystem. most of these strains are from the non-o1/non-o139 serogroups (nags), but toxigenic o1 stra ... | 2013 | 24303045 |
| complete genome sequence of a sucrose-nonfermenting epidemic strain of vibrio cholerae o1 from brazil. | we report the genome sequence of vibrio cholerae strain iec224, which fails to ferment sucrose. it was isolated from a cholera outbreak in the amazon. the defective sucrose phenotype was determined to be due to a frameshift mutation, and a molecular marker of the latin american main epidemic lineage was identified. | 2012 | 22535947 |
