[determination of sero- and biovariants of foreign and soviet strains of yersinia enterocolitica].the results of the typing of the biochemical and serological variants of yersinia enterocolitica strains from the ussr (10 strains) and other countries (32 strains) are presented. most of these strains, belonging to biovars 1 and 5, could be determined with the use of the antigenic scheme which was proposed by knapp only for biovars 2, 3 and 4. the strains isolated in leningrad and in the far east were found to belong to serovars 6,30; 7,8; 12,25 and 5b according to the scheme proposed by wauter ...1979160171
[the prevalence of yersinia and its serologic variants in patients with acute intestinal diseases of undetermined etiology in leningrad].among yersinia enterocolitica strains of 32 serovars, proposed as typing strains, some strains were found to belong to new species. y. enterocolitica sensu stricto was represented by 21 serovars in the collection of typing strains. the occurrence of different yersinia serovars in patients with acute enteric diseases of unknown etiology in leningrad in 1983-1986 was determined with the use of the set of monoreceptor to 21 serovars. out of 2,947 cultures studied by biochemical and serological meth ...19892531522

prevalence of enteropathogenic yersinia in estonian, latvian, and russian (leningrad region) pigs.tonsils of 457 fattening pigs from estonia (n = 151), latvia (n = 109), and the leningrad region of russia (n = 197) were collected between 2004 and 2007 to study the prevalence of enteropathogenic yersinia in slaughter pigs. yersinia enterocolitica and yersinia pseudotuberculosis were isolated by selective and cold enrichment. pathogenic y. enterocolitica and y. pseudotuberculosis were identified by pcr targeting the chromosomal genes ail and inv, respectively. the presence of the virulence pla ...200919580449
