Investigation of genetic polymorphism of Russian rape and turnip rape varieties using SSR and SRAP markers.

Rapeseed (Brassica napus L.) and turnip rape (B. rapa L.

[The electrophoretic typing of rotaviruses in the clinico-epidemiological study of infection].

The electrophoretic study of the RNA of human rotavirus strains (1146 strains) circulating in 9 cities at the territory of the European part of the RSFSR was carried out. The electrophoretic (EP) types of rotavirus were established in each individual area. The study revealed that the most widespread rotaviruses responsible for the majority of gastroenteritis cases are those with the long EP type of RNA, characterized by the joint migration of segments 2, 3 and 7 (the 3rd EP type of RNA).

[The effect of different Yersinia pestis antigens on the cellular link in immunity].

Immunization with live plague vaccine has been shown to give no protection to thymectomized mice from subcutaneous challenge with Y. pestis virulent strain. Under the action of the vaccine or individual Y.

[Use of gnotobiotic animals for the study of the pathogenesis of cholera intoxication].

Germ-free suckling rabbits and minipigs can be recommended as models suitable for the study of different aspects of the pathogenesis of cholera intoxication. In minipigs, individual representatives of intestinal autochthonous microflora produce different effect on the sensitivity of the animals to the toxigenic and choleragenic action of Vibrio cholerae antigen introduced by oral administration, that should also be taken into consideration in the determination of residual toxicity during the trial of new vaccine preparations against cholera.

[Morphological study of the damaging effect of an EB vaccine strain of the plague microbe in inbred mice].

The data obtained during the study of the morphological changes in the internal organs and blood of 6 mouse strains at the early stages of anti-plague immunity are presented. It has been established that the introduction of 5.10(3) and 1.
