| tracking of clinical and environmental vibrio cholerae o1 strains by combined analysis of the presence of toxin cassette, plasmid content and eric pcr. | clinical and environmental vibrio cholerae o1 strains associated with the cholera epidemic in the luanda province of angola from 1991 to 1994 were tracked by toxin distribution, plasmid content and chromosomal polymorphism of the enterobacterial repetitive intergenic consensus (eric) sequences by pcr fingerprinting. to follow the distribution of ace, zot and ctxa toxin genes, 6 specific pcr tests were applied to 100 vibrio strains, after preliminary hybridization experiments. clinical isolates o ... | 1997 | 9322067 |
