[Effectiveness of dioxidine in a model of Staphylococcal necrotic-suppurative encephalomeningitis (according to electron microscopy data].

Dioxidine efficacy was studied on a model of staphylococcal necrotic suppurative encephalomeningitis. There was a relationship of the development of disease signs to the value of the contaminating dose. Dioxidine was shown to have a therapeutic effect.

[Effects of quinolone carboxylic acid derivatives on the ultrastructure of gram-positive and gram-negative bacteria].

The impact of oxolinic acid, pefloxacin and ciprofloxacin on the structure of Staphylococcus aureus, Pseudomonas aeruginosa and Serratia marcescens was studied. The concentration dependent effects were revealed. Comparative estimation of the action of the compounds by the content of normal, dead and changed cells in the cultures showed that ciprofloxacin had advantages.

[Electron microscopic studies of experimental staphylococcal infections in mice as chemotherapeutic models].

Study of ultrastructural changes in the brain and renal tissues has shown that both intracerebral and intraperitoneal administration of staphylococcus in low infecting doses leads to the development in the brain and renal tissues of acute purulent inflammation, with a dramatic growth of infectious process and involvement of all parts of the organs under consideration. The presence in the brain tissues and in its meninges of inflammatory pyonecrotic foci might attest to the necrotic purulent encephalomeningitis, whereas the presence in the cortex and renal medullary substance of histiolymphocytic infiltration and foci of necrosis might be evidence of necrotic glomerulonephritis of bacterial etiology.
