[Increasing the effectiveness of the method of Staphylococcus phage-typing].

Eight nutrient media used for St. aureus phage-typing were assessed in parallel experiments. 22 test strains of St.

[Simulation of the Baird-Parker media formula based on Soviet ingredients for the isolation of Staphylococcus aureus].

A medium has been prepared based on Soviet nutrient agar and reagents supplemented by ingredients from Baird-Parker's medium. Its growth and selective properties are close to those of Baird-Parker's medium. The new selective medium has been recommended for isolation of S.

[Use of the agar drop method for the quantitative calculation of mesophilic aerobic and facultatively anaerobic microorganisms and coliform bacteria in food products].

The tests in agar dishes and agar drops were used simultaneously to determine the amount of mesophilic aerobic and facultative-anaerobic microorganisms and coliform bacteria in certain food products. The results of the analysis of more than 40 samples of different food products in both the tests have proved to be identical. The method can be recommended for practical use at laboratories of sanitary-epidemiological stations during prophylactic sanitary control, and at laboratories of food manufacturing enterprises.

[Experimental basis of principles for creating microbiologic standards for food products for children during the 1st year of life].

Standard media were designed simulating the gastro-intestinal contents of infants during the first year of life. These media were used in the in vitro tests to study the viability of a number of potentially-pathogenic microorganisms. It was shown that S.
