the clinical spectrum of reiter's syndrome and similar postenteric arthropathies.certain infections of the genitourinary and gastrointestinal tracts, such as nongonococcal urethritis, dysentery and yersiniosis, precipitate characteristic arthritic syndromes in genetically susceptible individuals. eye and skin lesions in the form of conjunctivitis, iritis, keratodermia blenorrhagica and erythema nodosum occurring in association with particular distributions of arthritis make recognizable clinical entities. reiter's syndrome may be diagnosed with certainty from the presence of ...1979159795
[proline-dependent wild strains and proline-dependent mutants of the plague microbe].it is found that the growth of yersinia pestis wild strains, isolated from citellus musicus menetrié in the central caucasus, depends on the presence of proline in the medium. proline can not be substituted by glutamic acid, other amino acids or vitamins. 28 proline-requiring mutants were selected from y. pestis marmot strain 20b. three groups of proline-requiring y. pestis mutants are established, similar to those of escherichia coli. the requirement of proline does not affect the virulency, pi ...1979159850
[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
ultrastructure of lipopolysaccharides of yersinia enterocolitica, salmonella typhimurium and escherichia coli.the fine structure of isolated lipopolysaccharides (lps) from the rough and smooth form of an yersinia enterocolitica strain (ye 75 r/ye 75 s) and from smooth forms of salmonella typhimurium (s 1010) and escherichia coli (essen) were examined electron-microscopically by negative staining. partial denaturation of lps in tris-buffer with acid and/or polymyxin b treatment revealed a common structure of strandlike lps. electron-microscopically, lps-strands were found to consist of two identical sub- ...1976185850
microbial agents of the owl monkey (aotus trivirgatus).a survey of the microbial flora in the owl monkey (aotus trivirgatus) has led to the isolation of numerous bacterial, fungal, and viral agents. some of the bacterial and fungal agents, particularly dermatophilus, pasteurella, salmonella, shigella, yersinia, streptococcus, staphylococcus, and candida are known pathogens. viruses belonging to the herpesvirus, adenovirus, paramyxovirus, and papovavirus groups have been isolated from the owl monkey. most of these viruses were recovered as latent age ...1976190470
