[Genome characteristics of a new group of microorganisms in the Vibrionaceae family].

A new group of microorganisms isolated from river and sewage water was studied by the method of molecular DNA-DNA hybridization and included into the family Vibrionaceae on account of their phenotypical properties. The genomes of the microorganisms belonging to this group proved to be highly similar (41-92% of homologies), which suggested that they were related on the genus level. The degree of similarity between the nucleotide sequences in the DNA of the bacteria under study and the DNA of other representatives of the family Vibrionaceae (the genera Vibrio, Beneckea, Aeromonas, Plesiomonas) amounting to 10-20% of homology indicates that the group of microorganisms under study forms a separate genus within the family Vibrionaceae.
