[Soy hydrolysate-based nutrient media: development and study of biological properties].

By using the designed soy hydrolysate, the authors developed dry nutrient media that were analogues of trypticase soy broth, trypticase soy agar, and Eugon agar. The media showed a high sensitivity and a significant accumulative activity against test strains that belonged to different taxonomy groups and they were as good as the known Merck media in these parameters and in the number, size, and shape of colonies.

[Development and diagnostic value evaluation of a nutrient medium for the yield and isolation of hemoculture].

The effectiveness of the bacteriological study of the blood depends in many aspects on the quality of nutrient media. The currently approved nutrient media for the isolation and yield of hemocultures have low isolation rates and require prolonged time for the isolation of causative agents. A two-phase nutrient medium for the yield and isolation of hemoculture has been developed.

[Selective nutrient medium for the isolation of Bacillus cereus].

A selective dried medium for the isolation of B. cereus from clinical material and foodstuffs has been developed. The medium has high selective properties which ensure the isolation of B.

[A selective nutrient medium for isolating clinical strains of Escherichia coli O157:H7].

A dried selective culture medium, electrolyte-deficient sorbitol agar (EDS agar), for the isolation and preliminary identification of E. coli O157:H7 from clinical material has been developed. The medium is not inferior in its quality to analogous foreign media and requires no scarce ingredients for its manufacture.
