[Experimental non-culturable Vibrio cholerae eltor and its biological properties].

In experiments with the cultivation of V. cholerae eltor under the conditions of high salt concentration, as well as low temperature and deficiency in nutrient substances, uncultivable forms (UF) of toxigenic and nontoxigenic vibrios were obtained. The absence of growth of seeded vibrios after the filtration of samples (with a filter of 0.

[Adaptive mechanisms in the ecology of the pseudotuberculosis microbe].

The paper presents the radiorespirometric and enzymatic findings of the insensitivity of catabolism of glucose and acetate in Y. pseudotuberculosis cells. The reduction in a Y.

[Experimental anthrax infection in laboratory animals with differing species susceptibility to the causative agent].

In guinea pigs and noninbred white mice, infected subcutaneously with anthrax which resulted in their death, characteristic generalized infection with the hematogenic contamination of their organs and the signs of intoxication and shock could be observed. In inbred white rats (Fisher 344) the invasion and dissemination of B. anthracis are relatively slightly pronounced, the phenomena of intoxication and shock being clearly prevalent.

[Specific intoxication in anthrax infection].

The pathomorphological picture of experimental B. anthracis infection in white rats (strain Fisher-344) essentially corresponds to experimental anthracic intoxication with very moderately pronounced morphological manifestation of B. anthracis invasion.

[Anthrax toxin dynamics in the body].

Anthrax toxin introduced subcutaneously into white rats Fisher-344 caused specific intoxication accompanied by characteristic pathomorphological changes and, when studied by the immunoperoxidase method in histological sections, could be detected in the blood stream (in plasma) and in the cytoplasm of macrophages (in the lungs and the spleen). The content of the preparation introduced into the animals in the blood stream is directly related to its toxicity, being probably indicative of the relative functional failure of the macrophagal system.
