[Typing staphylococci of intestinal origin according to the character of their bacteriocins]

Results of studying the properties of bacteriocines of pathogenic staphylococci isolated from children with intestinal disturbances are presented; morphology of the inhibition zones, the capacity to penetrate through cellophane, the rate of diffusion in agar and the period of inactivation pointed to the nonhomogeneousness of the 275 strains under study and a possibility of their differentiation with the aid of a provisional scheme including 12 bacteriocinogenotypes. Reference of all or the majority of the strains isolated from the same person to the same bacteriocinogenotype of the scheme pointed to a possibility of its practical application.
