| [association between vibrio cholerae and zooplankton of estuaries of são marcos bay/são luis - ma, brazil]. | this study was carried from october 1997 to october 1998 with the purpose of investigating the link between the species vibrio cholerae and zooplankton in the estuaries of rivers anil and bacanga in são luis, maranhão. research of viable but non culturable forms of vibrio cholerae o1, and analyze the correlation between ph values, salinity and water temperature with the presence of bacteria in zooplankton samples. the traditional method of cultivation and fluorescent antibody technique were appl ... | 2004 | 15334265 |
| [molecular study of vibrio cholerae non-o1 isolated from zooplankton of são marcos bay/são luis - ma, brasil]. | the study was developed to analyze the plasmidial dna, research virulence genes and identify genetic diversity of 31 strains of vibrio cholerae non-o1 isolated from zooplankton of the bacanga and anil rivers in são luis-ma. the study of plasmidial dna showed 2 or 3 plasmids from 10 strains between 5.5 and 40 kilobasis. there was only single ribotype pattern. pcr methods did not show the genes ctxa, ace and zot, while radp-pcr identified genetic diversity in the strains, showing the potential for ... | 2004 | 15334266 |
