| [pcr-detection of markers for epidemiologically-significant strains of vibrio cholerae 0139, isolated in siberia]. | fourteen v. cholerae 0139 strains were isolated in 1996-1999 in siberia from the ob river (novosibirsk) and bogs and lakes (irkutsk). the strains were tested in pcr for the key virulence determinants (ctx ab, tcp, acf). the genomes lacked these elements, and therefore the strains were acknowledged avirulent. the results correlate completely with the data of phenotypical analysis, characterizing the pathogenic characteristics of isolated strains. | 2001 | 11449796 |
