[The biological properties of Rahnella aquatilis strains isolated in different regions].

Biological properties (morphological, tinctorial, cultural, biochemical, serological, genetic) of 25 Rahnella aquatilis strains, 21 of them being isolated in the territory of Ukraine and Russia, have been studied with results presented. The research data will allow specialists to isolate these microorganisms from biotic and abiotic objects of the environment and to differentiate them from other representatives of Enterobacteriaceae.
