STRAIN OF BACTERIUM YERSINIA PESTIS USED AS TEST-STRAIN OF CENTRAL-CAUCASUS HIGH MOUNTAINS PLAGUE LOCATION Russian patent published in 2008 - IPC C12N1/20 C12Q1/04 C12R1/01 

FIELD: medicinal microbiology.

SUBSTANCE: invention reports the strain of bacterium Yersinia pestis C-781 obtained by direct inoculation if visceral organs of mountain suslik on solid Hottinger agar at pH 7.2 ± 0.2 unit. The strain is passed five times through body fleas Xenopsylla cheopis representing active carriers of plague and stored on Hottinger slant agar at pH 7.2 ± 0.2 unit in soldered tubes at temperature +4°C for one year and used then for infection of laboratory animals (white mice, guinea pigs). Found capacity for retention and recovery of virulence, stability of biological properties of the strain allow using the strain Yersinia pestis C-781 as test-strain for detecting strains of plague microbe in Central-Caucasus high mountains natural location of plague.

EFFECT: valuable properties of strain.
