[Production of toxic shock exotoxin by Staphylococcus aureus strains resistant and sensitive to antibiotics].

Three hundred and ninety two strains of S. aureus isolated from bacteria carriers and patients with staphylococcal infections in different regions of the Soviet Union were investigated. 55.

[Species characteristics of coagulase-negative staphylococci of animal origin].

The specific identification of 271 strains of coagulase-negative staphylococci isolated from different animals (cows, sheep, swine, hens, monkeys, minks, sables, foxes, etc.) was carried out according to the scheme of Akatov--Devriese. Species could be determined in 77.

[Coagulase-negative Staphylococci isolated from patients. III. Phage typing].

Coagulase-negative staphylococci of clinical origin were subjected to phage typing by means of phages from the experimental Dutch (Verhoef) and American (Paris) sets. These sets of phages were used to study 153 and 378 strains, respectively. The Dutch phages could lyse 30.

[Effect of delayed hypersensitivity on the development of an intradermal focus of a staphylococcal infection].

Delayed hypersensitivity (DH) was induced in rabbits by introducing killed St. aureus culture in incomplete Freund's adjuvant. 7 days later the animals were infected intradermally with alpha-toxigenic and leukocidin-active St.
