[Current status of laboratory diagnosis of infections caused by nonspore-forming anaerobes and ways of its improvement].

Nonspore-anaerobic bacteria are the most common pathogens of purulent opportunistic infection. However, this group of infections is not recorded in our country due to the lack of national culture media and special laboratory equipment for anaerobic bacteriology. The laboratory diagnosis of infections caused by nonspore-forming anaerobes are analyzed and urgent measures to solve this topical problem are defined.

[Cultivation of asporogenous anaerobic microorganisms in media of various compositions].

The comparative evaluation of the quality of experimental dried culture medium for the isolation and cultivation of anaerobic microorganisms, developed on the basis of locally produced ingredients without unavailable raw material suitable for human consumption, and enriched thioglycolic medium has revealed the advantage of the former and permits its recommendation for practical use in laboratories.

[Antibiotic sensitivity of an Escherichia coli strain used for preparing colibacterin].

Sensitivity of a E. coli strain and commercial colibacterins prepared with its use to 18 antibiotics was tested. The MIC was determined by the method of serial dilutions.

[Determination of the viability of Escherichia coli M17 by its respiratory activity].

The possibility of the determination of the number of viable E. coli M17 in Colibacterin by the rate of oxygen consumption, based on measuring the slow fluorescence of these bacteria, has been studied. The direct correlation between the number of live E.
