[Identification of conditionally pathogenic enterobacteria in laboratory practice in the diagnosis of acute intestinal diseases].

Identification of 361 cultures isolated from patients suffering from various acute intestinal diseasesand from persons who had sustained them, as well as from contacts and persons examined prophylactically with the use of various biochemical tests showed that ty their taxonomic properties the cultures were referred to conditionally-pathogenic representatives of Enterobacteriaceae of the corresponding genera:Citrobacter, Hafnia, Klebsiella, Proteus, Providencia. Serological typing of the strains of bacteria of the Citrobacter pointed to the most frequent circulation of the strains of the serological groups 04, 01, 03, 013, 05, 022, 08; among these groups 04, encountered among all the categories under study, prevailed. At the current stage of identification of conditionally pathogenic enterobacteria in practical laboratories it is of expedience to use in the diagnosis of intestinal diseases the serological typing along with a complex from several additional biochemical tests.
