[Comparative evaluation of protein hydrolysates in designing their based universal culture medium for the diagnosis of plague and cholera].

Various protein hydrolysates made in Russia and foreign countries were comparatively evaluated to use them to design a universal agarized culture medium for the diagnosis of plague and cholera. Pancreatic baker's yeast broth was found to be most effective among the test media.

[New nutrient medium for the cultivation and isolation of the plague microbe ChDS-37 as an element of the mobilization reserve of specialized antiepidemic teams of the Russian Inspectorate for the Protection of Consumer Rights and Human Welfare].

A new nutrient medium has been designed to culture and isolate the plague microbe ChDS-37 on the basis of the pancreatic digest of baker's yeast. The results of laboratory tests of the designed medium, by using 10 plague microbe strains and those of approval during the tactical and special training of a specialized antiepidemic team (SAET), suggest that the medium has some advantage over reference media and creates prerequisites for being incorporated into the mobilization reserve of a SAET.

[Activity of oil isolated from Amaranth seeds on energetic functions of rat liver mitochondria after adrenaline introduction].

It has been shown that a three-week feeding of rats with oil derived from seeds of amaranth (Amaranthus cruentus L.) leads to a moderate activation of respiration of coupled and uncoupled rat liver mitochondria (MCh) that oxidize succinate and succinate + glutamate, as well as alpha-ketoglutarate and alpha-ketoglutarate + malonate. In animals receiving the amaranth oil, the injection of adrenaline did not affect the oil-activated respiration of MCh during succinate oxidation; i.

[Effect of various amino acids and ammonium salts in a synthetic culture media on the cholera enterotoxin production].

The influence of amino acids and ammonium salts on the production of cholera enterotoxin (CT) by 3 Vibrio cholerae strains of different biovars and serogroups was evaluated. As revealed in this study, toxin formation in each of the strains was quantitatively and qualitatively determined by their individual sets of amino acids. The amino acid compositions ensuring the maximum production of CT by the V.

[Dynamics of the isolation and biological properties of Vibrio cholerae cultures, serogroups 01 and 0139, isolated from water reservoirs and sewage water on the territory of the city of Rostov-on-Don].

The dynamics of the isolation of V. cholerae cultures from various water objects on the territory of Rostov-on-Don during the period of 1994-2001 was analyzed and biological properties of 14 such cultures were studied. In the absence of epidemic complications during the above-mentioned period, a growth in the amount of V.
