INDICATOR STRAIN AND METHOD OF TITRATION OF COLICIN GROUP E

摘要

FIELD: microbiology. SUBSTANCE: strain of microorganism E. coli p. S- mutant of universal indicator of E. coli Φ is selected from resistant colonies grown at the zone of colicin Saction (wild strain of Zonne schigella) to indicator strain E. coli Φ. Indicator strain p. Eis used in complex with the known indicator strains from the different collection for typing colicin Eand its combination with colicin Eand group S. Indicator properties of the known strains and strain p. Shave been proved firstly at their testing using the broad set of standard-strains as colicin producers. Strain E. coli p. Sshows resistance to only colicin E((S)) of type strain 6 from Ghorack collection and ensures to detect in complex with the known indicators - a single colicin Eand its combination with colicin Eand group E. EFFECT: enhanced method of bacterium detection.
