[Immunobiological properties of bacteria].

Opsonins found on the surface of microbial cells in vivo and ex vivo are characterized. The possibility of their visualization by immune electron and fluorescent microscopy has been demonstrated. Opsonins are shown to play a role in immune-mediated adhesion of bacteria to phagocytes and erythrocytes and formation of virus-bacterium associations.

[Evaluation of the hazard of soil-polluting chemicals upon exposure of experimental animals].

The experimental study of the biological activity of the modified calcium chloride produced by a Volgograd plant and that of ash-and-slag of the pharmaceuticals resulting after combustion of a pyrolytic mixture of filtration burning could establish various hazards of these substances.

[Human microecology studies at Department of Microbiology with Virology and Immunology, I.M. Sechenov Moscow Medical Academy].

Studies of human microflora in health and disease and during exposure to professional and ecological factors is a traditional problem solved for many years by staff members of Department of Microbiology with Virology and Immunology, I. M. Setchenov Moscow Medical Academy.

[Skin microbiocenosis in patient with chronic dermatoses].

The skin microflora of patients with chronic dermatoses (atopic dermatitis and psoriasis) have been studied by the original "Bactotests" method. The data thus obtained indicate that the clinical picture of the disease is related to the severity of skin dysbacteriosis. The electron-microscopic study of 2 staphylococcal strains isolated from patients has revealed the presence of the immunoglobulin cover (capsule-like outer sheath consisting of immunoglobulins and other humoral protective factors) on the cell wall of these bacteria.
