[Differentiation of methicillin-resistant strains of Staphylococcus aureus by prophage specificity].

By inducing with mitomycin C the following phages were isolated from all the tested 32 methicillin resistant strains of S. aureus: the serogroup B phage was isolated from 2 strains, the serogroup B and F phages were isolated from 5 strains and the serogroup F phage was isolated from 25 strains. The phages were divided into 5 groups by the antiphage immunity. In group 1 of the phages 4 additional phages were specified. By the specificity of the prophages in the cultures all the strains were divided into 5 groups. Group 1 of the cultures was divided into 5 subgroups (A, B, C, D and E).

[Experimental phages for differentiating nontypable methicillin-resistant Staphylococcus aureus].

The possibility of using phages, isolated from the lysogenic cultures of methicillin-resistant staphylococci and modified in methicillin-resistant cultures of phage 85, for the differentiation of nontypable staphylococcal strains has been studied. The variants of phage 85 cannot be used for the determination of differences between the strains of methicillin-resistant cultures; they are not suited for typing. For this purpose the collection of phages isolated from lysogenic methicillin-resistant cultures should be used.

[A new collection of phages for typing methicillin resistant Staphylococcus aureus].

A new collection of phages for typing methicillin-resistant S. aureus (MRSA) is proposed. The collection includes phage 85 (modified by the MRSA strain), capable of selecting strains with the similar specificity of the restriction-modification system, and 9 MRSA-induced phages. The latter differentiate MRSA strains according to the specificity of prophages present in bacterial cells. The use of this phage collection has permitted the typing of MRSA strains insensitive to the phages of the international collection. Among these cultures an epidemic strain has been detected and the source of its spread in the burn center has been established.
