[Ecological diagnosis of pyoseptic diseases in newborns using the "Diastaph" disc].

The etiological spectrum of pyoseptic diseases was studied in 113 newborns. It was established, that between 187 strains of microorganisms, belonging to 19 species, 73.3% were staphylococci and streptococci, 25.

[The etiological spectrum and immunosuppressive properties of the causative agents of pyoderma].

The etiological spectrum and some immunoaggressive properties of microorganisms, that cause pyoderma in newborns which were isolated from patients have been studied. It was established that staphylococci (mostly coagulase-positive S. aureus, S.

[HLA-system antigens in patients with food poisonings caused by opportunistic bacteria].

A total of 286 convalescents after toxico-infections caused by opportunistic microorganisms were examined. The panel of anti-HLA sera permitted the typing of 34 HLA antigens, class 1. As a result, the development of the disease was found to be directly associated with antigen HLA-B17 and inversely with antigen HLA-A2.

[The role of autoimmune reactions in the development of disseminated sclerosis].

The immune status was investigated in 97 patients with multiple sclerosis. Patients of this group showed marked changes at the cellular lever of the immune system. T-lymphocytopenia was accompanied by a dysbalance of the main correlative cells according to a relatively hyposuppressor variant of immune deficit with formation of circulating immune complexes and thermodependent lymphocytotoxic autoantibodies.
