STH facilitates the maintenance of weight in animals irradiated with sublethal and minimum lethal doses of X-rays, but does not increase their survival times. Joint administration of STH, DOCA and salt solution exerts a significant influence on the weight of the animals and hastens their death. The administration of STH prior to irradiation with sublethal doses of X-rays exhibits a definite protective effect. In irradiated animals, STH increases the weight ...

THE SPREAD OF LEPTOSPIRAE IN THE BODY AND ANTIBODY FORMATION IN EXPERIMENTALLY INDUCED LEPTOSPIROSIS IN IRRADIATED ANIMALS

JUL 1968

8 pages

Authors: R. V. Petrov; ARMY BIOLOGICAL LABS FREDERICK MD

In the animals inoculated with the pathogen of leptospirosis 2 to 24 hours post irradiation by X-rays, the antibody production was suppressed, but upon inoculation 48 hours after irradiation, the formation of antibodies was completely absent. The leptospiremic phase of the infection lasts longer in the irradiated animals than in the control animals. Thus, the longer the duration of the leptospiremia the more intensely the antibody formation is repressed. The ...

The intraspecies and interspecies relationships of microorganisms are not something hard and fast. They are not always relationships of either pure synergism or pure antagonism. Their character can change depending upon the concrete conditions of the microorganisms' existence. The character of intraspecific and interspecific relationships cannot serve as a criterion for the determination of the microorganisms' species.
