[Immune reactivity disorders in poisoning by the pyrethroid sumi-alpha].

After subchronic intoxication with synthetic sumi-alpha pirethroid rats developed pronounced changes of macrophagocytic function; reduction of cell-mediated and humoral immunity, accumulation of pathogenic circulating immune complexes. In these conditions one-week thymalin treatment produced a normalizing effect. Sodium nucleinate was of low efficacy.

Classification of coagulase-negative staphylococci in diagnostic practice.

When the Schleifer and Kloos classification was used for the identification of 300 clinical isolates of coagulase-negative staphylococci (CNS), S. epidermidis together with S. saprophyticus was found to amount to 21.

[Phosphatase-negative Staphylococcus epidermidis].

As a result of the study of a number of additional characteristics, more than a half of the cultures, formerly identified as phosphatase-negative S. epidermidis according to the scheme of the International Subcommittee on the Taxonomy of Staphylococci and Micrococci, have been shown to be more similar to S. Hominis and S.

[Species makeup of coagulase-negative staphylococci of clinical origin].

The classification of Kloos--Schleifer was used for the identification of 175 clinical strains of coagulase-negative staphylococci. The species of staphylococci in 50.3% of the cultures were determined; as a result, S.
