| examination of the envelope antigen k1 in yersinia enterocolitica which was identified as fimbriae. | the envelope antigen k1 found in the majority of yersinia enterocolica (y. ent.) strains belonging to the o group 10 as described by wauters, was re-examined under the electron microscope, and identified as being fimbriae. these fimbriae envelop the bacterial cell with a dense fringe. single filaments show a width of 2.5 to 1.7 nm whilst their length is variable, often many times the size of the bacterial cell. fimbriated y. ent. cultures do not form pellicle, and the haemagglutination test is n ... | 1976 | 936830 |

| properties of pgc1, a lac plasmid orginating in yersinia enterocolitica 842. | pgc1, a self-transmissible lac plasmid that originated in yersinia enterocolitica 842, is described. this plasmid is freely transmissible between strains of y. enterocolitica and from such strains to strains of escherichia coli. the plasmid can also be transferref among g. coli strains and back to y. enterocolitica, although at a greatly reduced frequency. pgc1 has a molecular weight of about 33.0 x 10(6), has a base composition of about 44 mol% guanine plus cytosine, and is fi-. | 1976 | 956120 |
| [yersinia enterocolitica in acute appendicitis, lymphadenitis mesenterialis and regional enteritis (author's transl)]. | in 895 patients operated on for acute appendicitis we found yersinia enterocolitica in 41 cases. another two cases were detected in postoperative serological examinations. lymphadenitis mesenterialis was present in 17 cases during operation. once we detected a regional enteritis. histological examination of the appendix revealed a purulent inflammation in 21 cases and a phlegmonous-gangrenous inflammation in 4 cases. the other 18 patients suffered from oxyuriasis, coprostasis or scars of the app ... | 1976 | 961157 |
| yersinia enterocolitica isolates from humans in california, 1968-1975. | this paper reports on the serological and biochemical characteristics of 24 human isolates of yersinia enterocolitica submitted to the california department of health from 1968 through 1975. nine different serotypes were represented. the majority of strains were serotype o:8 (six strains) and serotype o:5 (five strains). sources of the isolates included feces (12 cases), blood (3), sputum or throat (3), bile or bowel drainage (2), wounds (2), breast abscess (1), and skin abscess (1). clinical hi ... | 1976 | 965477 |

| isolation of yersinia enterocolitica from danish swine and dogs. | seventeen strains of yersinia enterocolitica were isolated on examination of the caecal contents from 100 bacon pigs at slaughter. in another material consisting of 222 pigs with various diseases, the bacterium was found in 12 cases. three out of 40 dogs were positive for the bacterium. seven of the porcine and one of the canine strains belonged to serotype o 3, which is a human pathogen. | 1976 | 970137 |
| a five-year survey of human yersinia enterocolitica infections in hungary. | human infections associated with yersinia enterocolitica in hungary in the years 1969-1974 have been surveyed. during this period the public health laboratory network isolated 1355 strains from 1096 persons. the number of isolates according to sero-groups was: 1343 o3, 6 o9, 2 o1, 2a, 3 and 1 strain for o5, o6, o1o and o15 each. (ii) a total of 2192 serum specimens from patients gave positive agglutination reaction with antigen o3 in 26.8%, with antigen o9 in 3.2%. (iii) fifty-six per cent of ba ... | 1976 | 970232 |
| [experimental infection of axenic mice by "yersinia enterocolitica" (author's transl)]. | although most of yersinia enterocolitica strains isolated from man have no pathogenicity for laboratory animals, it has been demonstrated that some strains are pathogenic for conventional mice and that most of the strains are probably pathogenic for nude mice. the authors report the results of the infection of germ-free mice with a strain of y. enterocolitica which is non pathogenic for holoxenic mice. it appears that c3h/he mice are sensitive to the infection by gavage or aerogenic and peritone ... | 1976 | 970831 |

| [joint manifestations of yersinia enterocolitica infections]. | different recent studies, notably scandinavian studies, have described a "rheumatism" caused by yersinia enterocolitica infection. the picture usually seen is that of a subacute, febrile oligoarthritis predominantly in the lower limbs, associated with diarrhoea and hyperleucocytosis, polynucleosis, and a marked increase in the sedimentation rate. benign carditis may also be associated. the diagnosis rests on the discovery of the organism by coproculture and on serodiagnosis. evolution is favoura ... | 1976 | 981921 |
