[Mitogenic activity of Staphylococcus aureus metabolites in cultures of whole and T- and B-fractionated human lymphocytes].

The stimulating action of the mitogenically active S. aureus metabolite (MASAM), described in earlier works, in the cultures of human peripheral blood lymphocytes, both nonfractionated and separated into T- and B-fractions, as well as the effect of macrophage removal on the sensitivity of lymphocytes to MASAM, were studied. MASAM was found to stimulate T- and B-lymphocyte cultures.

[Molecular profile of mitogen-active metabolites of Staphylococcus aureus].

A fraction with a molecular weight of 16000-24000 was isolated from 5-day S. aureus broth culture grown in the dialysate of Martin-Hottinger broth. At a concentration of 2-15 micrograms/ml this fraction induced the nonspecific blast transformation of human blood lymphocytes with the stimulation index 99.

[Characteristics of the mitogenic activity of different staphylococcal strains].

The mitogens of human peripheral lymphocytes were detected in the metabolic products of 59 out of 71 S. aureus strains. The preparations of S.
