| epidemiological typing of yersinia enterocolitica by analysis of restriction fragment length polymorphisms with a cloned ribosomal rna gene. | intra-species restriction fragment length polymorphisms (rflps) of yersinia enterocolitica were detected in assays with a cloned dna fragment from legionella pneumophila that included the 16s and 23s rrna genes. by use of this method it was possible to identify different rflp types within biogroups/serogroups which were indistinguishable by other means. thus the 37 biogroup iv/serogroup o3 strains isolated worldwide from pig carcasses, pork and human patients, were subdivided into five different ... | 1990 | 1973736 |

| role of the yersinia outer membrane protein yada in adhesion to rabbit intestinal tissue and rabbit intestinal brush border membrane vesicles. | the yersinia virulence plasmid confers on strains of yersinia pseudotuberculosis and y. enterocolitica an adhesive potential superior to the one encoded by the chromosome alone. we have evaluated the role of the plasmid-encoded outer membrane protein yada (formerly called yopl) in adhesion. insertional inactivation of the yada gene (formerly called yopa), which encodes yada, led to a reduction in the capacity of plasmid-carrying strains of y. pseudotuberculosis 0:iii and y. enterocolitica 0:9 to ... | 1991 | 2018636 |

| [enteropathogenic yersinias: pathogenicity factors and new diagnostic methods]. | a limited number of serotypes of yersinia enterocolitica and y. pseudotuberculosis is enteropathogenic for humans. during the last decade molecular biology contributed significantly to the understanding of the pathogenicity of these enteric agents. all human pathogenic yersiniae harbour a 70-kilobase plasmid which is essential for virulence expression. presently, thirteen plasmid-encoded polypeptides have been identified. two of them have been identified as true outer membrane proteins and at le ... | 1990 | 2076901 |
| [clinical aspects, diagnosis and therapy of yersinia enterocolitica infections]. | the predominant form (65% of all patients) of yersiniosis is mesenteric adenitis, resulting in enteritis, pseudo-appendicular syndromes, ileitis or colitis. the severity of this form depends to some degree on the age. extra-mesenteric forms (in 20-25%), focal infections by dissemination, the septic form and the lymphadenopathy syndrome may occur after or without previous enteritis. persistence of y. enterocolitica in lymphnodes and the galt is responsible for chronic and recurrent forms. seconda ... | 1990 | 2076902 |
