Yersinia enterocolitica BACTERIA STRAIN USED AS INDICATOR CULTURE FOR DETECTING MODERATE BACTERIOPHAGES OF LYSOGENIC STRAINS OF O1, O3, O12 SEROVARS Russian patent published in 2011 - IPC C12N1/20 C12N7/01 C12R1/01 

FIELD: medicine.

SUBSTANCE: invention can be used in laboratory diagnostics of Yersinia enterocolitica strains with using moderate bacteriophages FK-99, FK-100, FK-101 for intraspecific differentiation of a yersiniosis agent. The Yersinia enterocolitica 2012 strain is recovered from human in 1966 and deposited in the State collection of pathogenic bacteria of Russian Research Antiplague Institution "Microbe", No. KM-206. When used as a mentor strain, it enables the particle concentration of the phage preparations being equal to n·10-n·10 particles/ml.

EFFECT: use of the recovered phages in Yersinia enterocolitica on the indicator KM-206 offered under the invention provides the additional differentiation of lysogenic cultures from non-lysogenic and ensures the effectiveness of laboratory diagnostics of Yersinia enterocolitica.
