[Biochemical characteristics of strains from the Citrobacter and Hafnia genera and their laboratory identification].

A study of biochemical properties of 176 strains of coprocultures isolated from the patients and persons who sustained various acute enteric diseases, and also from contacts and persons examined for prophylaxis showed that they corresponded to the taxonomic definition of the Citrobacter and Hafnia genus. In connection with the similarity by biochemical properties between bacteria of Citrobacter and Salmonella genus and bacteria of Hafnia and Shigella genus it is of expedience in their identification and differentiation carried out in bacteriological laboratories in the diagnosis of enteric infections to use several biochemical tests.
