[The isolation of Vibrio fluvialis on the territory of the USSR].

For the first time V. fluvialis strains were detected on the territory of the USSR. The taxonomic position of these vibrios was determined by their nucleotide DNA composition (the content of guanine + cytosine was 49.3-51.0 mole%) and the characteristic features of their phenotype. The individual features of the strains consisted in their capacity for agglutination with cholera antisera, groups 01 and Inaba, in diagnostic dilutions in the presence of differences in genomes and phenotypes with cholera vibrios. Molecular hybridization DNA-DNA also gave no confirmation of their relationship to cholera vibrios (23-26% homology). The comparative study of V. fluvialis strains from the USSR and other countries by a broader set of their phenotypical signs confirmed their identity.
