[antigenic analysis and immunological studies of the uterotropic bacterial strains sh6 and 01 isolated from aborted cows].the uterotropic strains sh6 and o1 were studied immunoelectrophoretically to establish their antigenic relationship. the more readily diffusing component of the o-antigenic fraction of the strains proved immunologically identical with lpa of the r brucella organisms, while the slower component showed common determinants with the o-antigenic fraction of yersinia pseudotuberculosis. immunodiffusion revealed that the o-antigenic fraction of the o1 strain and lpa of the s brucella organisms contain ...197660821
enteritis in sheep, goats and pigs due to yersinia pseudotuberculosis infection.the features of naturally occurring yersinia pseudotuberculosis serotype iii infections in 16 sheep, one goat and 3 pigs, and y. pseudotuberculosis serotype i infections in 3 goats, are described. affected animals usually had diarrhoea and were in poor condition or emaciated. a number were moribund or dead when submitted for necropsy. thickening of the caecal and colonic mucosa was the only gross lesion attributable to y. pseudotuberculosis infection, with liver or other visceral abscesses not b ...19902098020
enteritis in cattle due to yersinia pseudotuberculosis infection.a selective medium was used to isolate yersinia sp from the intestinal tract of 222 scouring cattle in gippsland during 1985 and 1986. intestinal infection with y. pseudotuberculosis, particularly of serotype iii, was found to be especially prevalent in weaned calves, yearlings and young adult cattle. clinically affected cattle had a profuse liquid diarrhoea and many were systemically ill. haematological changes suggestive of infection were present in 38 of 49 of these cattle. at least 35 cattle ...19883056376
[campylobacter jejuni infections in slaughterhouse workers].complement fixing (c.f.) antibodies to campylobacter jejuni were detected in 83 slaughterhouse workers and 83 blood donors. workers were aged 18-65 years (mean, 41.7 +/- 12.3) and had worked in the slaughterhouse for 2-40 years (mean, 17.5 +/- 5.1). c.f. antibodies were detected according to mosimann's method and by including five antigens: campylobacter jejuni, yersinia enterocolitica types 03 and 09, yersinia pseudotuberculosis and brucella. positive titers were found in 12.1% of workers and i ...19883154982
[the epidemiology of yersinia infections in the central taiga subzone of the eastern european plain].the seroepidemiological survey of the population in four southern regions of the komi republic for the presence of pseudotuberculosis and enteric yersiniosis was carried out. the survey revealed a high level of seroconversions to with respect to enteric yersiniosis (26.2 +/- 2.7% with the average antibody titer being 2.6 +/- 0.2 log2) and rare contacts of the rural population with y. pseudotuberculosis (0.4%). moreover, the intensity of contacts of the population with the infective agent was fou ...19938067089
introduction into japan of pathogenic yersinia through imported pork, beef and fowl.yersinia was isolated from imported raw meat and fowl products by hela cell treatment and conventional koh-treatment, to obtain information on the origin of pathogenic yersinia in japan. forty-one strains of yersinia enterocolitica and one strain of yersinia pseudotuberculosis, serotype 4b were isolated from 38 (3.0%) of 1278 samples of pork, two (0.3%) of 612 samples of beef and two (0.3%) of 615 samples of chicken. y. enterocolitica isolates belonged to b:4/o:3 (biotype/serotype, 15 strains), ...19979105929
effect of bovine lactoferricin on enteropathogenic yersinia adhesion and invasion in hep-2 cells.bovine lactoferricin, a pepsin-generated antimicrobial peptide from bovine lactoferrin active against a wide range of bacteria, was tested for its ability to influence the adhesion and invasion of yersinia enterocolitica and yersinia pseudotuberculosis in hep-2 cells. the addition of non-cytotoxic and non-bactericidal concentrations of lactoferricin to cell monolayers before infection, under different bacterial growth experimental conditions, was ineffective or resulted in about a 10-fold increa ...200415096550
use of florfenicol in non-human primates.studies were undertaken to determine if florfenicol, an antimicrobial agent structurally similar to chloramphenicol, could be used as an effective broad spectrum antibiotic for the treatment of bacterial infections in primates. florfenicol was developed as an injectable antibiotic for use in cattle on an every other day dosing schedule. its broad spectrum activity, long duration of action following i.m. administration, and its safety as compared with chloramphenicol made it an attractive antibio ...200415102069
[mastitis caused by yersinia pseudotuberculosis in a cow].subclinical mastitis with a raised somatic cell count was diagnosed in a cow in her fifth lactation. it was caused by yersinia pseudotuberculosis, which can also infect humans. this is the first time that yersinia pseudotuberculosis has been isolated from a mastitis sample in the netherlands. despite treatment with antibiotics in the dry period, yersinia pseudotuberculosis was still present in the same quarter in the subsequent lactation. the somatic cell count was still high and milk production ...200515938449
serotypes of yersinia pseudotuberculosis recovered from domestic livestock.the serological identity of 234 strains of yersinia pseudotuberculosis recovered from domestic animals and birds in new zealand was determined by slide agglutination test. thirty strains were also examined by tube agglutination test. the strains were isolated from cattle (56), sheep (8), deer (117), goats (13), pigs (7), rabbits (6), guinea pigs (5), and aviary species of birds (22). all strains were isolated from animals or birds which had died or shown signs of ill health and amongst which dia ...198416031006
recovery of yersinia pseudotuberculosis from the faeces of healthy cattle.attempts were made to recover and serologically identify yersinia pseudotuberculosis from the faeces of groups of nine to twenty clinically healthy cattle eight to thirteen months old on each of 50 farms in the northern part of new zealand. yersinia pseudotuberculosis was recovered from 134 (26.3%) of 509 faeces samples from cattle on 42 (84%) farms and from nine of ten samples on two of these farms. serotypes i, ii, and iii were identified, of which serotype iii was by far the most common and a ...198516031106
