acute colitis caused by campylobacter fetus ss. jejuni.campylobacter fetus ss. jejuni has been recently recognized as a common human enteric pathogen; however, the pathology and pathophysiology of the enteritis caused by this agent are still largely obscure. we report 4 patients who presented with acute abdominal pain and bloody diarrhea and who had c. fetus ss. jejuni isolated from fecal cultures. each patient showed a fourfold rise in serum igg titer to the organism isolated. in all 4 patients colonic involvement was noted on sigmoidoscopic examin ...19807351284
production of diarrhoea and dysentery in experimental calves by feeding pure cultures of campylobacter fetus subspecies jejuni.pure cultures of campylobacter fetus subspecies jejuni of bovine origin were used to inoculate three ruminating calves in each of two experiments and three milk-fed calves in another. inoculated animals all developed clinical signs which included fewer (to 41 degrees c), diarrhoea and sporadic dysentery within one to three days of inoculation. diarrhoeic faeces were dark, mucoid, of uniform consistency and were passed for six to 15 days. the eight control animals did not develop this syndrome. c ...19807445343
the clinical spectrum of campylobacter fetus infections: report of five cases and review of the literature.five cases of extra-intestinal campylobacter fetus infections are described and an additional 242 cases are reviewed from the literature. a variety of clinical syndromes are encountered including endocarditis; thrombophlebitis; meningitis; pneumonia and pleuritis; and infectious arthritis. thirty-eight per cent of patients presented with bacteremia enteritis. campylobacter fetus demonstrates a preference for endovascular surfaces. the majority of patients are male and have an underlying illness. ...19807267960
isolation of campylobacter fetus subsp. jejuni from bangladeshi children.to determine the prevalence of infection with campylobacter fetus subsp. jejuni in bangladesh, culture surveys were conducted among three populations. in dacca, campylobacter was isolated from 5.2% of 97 individuals with clinical dysentery and from 12.3% of 204 patients with only diarrhea. this difference may have resulted from a greater representation of young children in the second group. campylobacter was isolated from 17.7% of the 141 healthy village children aged 1 to 5.5 years and from 38. ...19807309841

mucosal invasion in campylobacter enteritis.campylobacter fetus subspecies jejuni has recently been recognized as a significant cause of enteritis in humans. the organism has been previously postulated to cause illness by direct invasion of the mucosa of the gastrointestinal tract, but this has not been documented. reported is a case of campylobacter enteritis in which mucosal ulceration and crypt sbscesses were seen on rectal biopsy, suggesting that the pathogenesis of campylobacter fetus enteritis involves direct mucosal invasion.19807377140
campylobacter colitis presentin as inflammatory bowel disease with segmental colonic ulcerations.campylobacter fetus subspecies have recently been recognized as an important cause of diarrheal illness in humans. we report a case of culture positive c. fetus colitis with colonoscopic findings of segmental mucosal edema, loss of normal vascular pattern with ulceration, and patchy involvement of mucosa. these colonoscopic findings were similar to those seen in granulomatous colitis. however, these findings may be difficult to distinguish from a number of other colonic mucosal diseases such as ...19807380209
cellular fatty acid composition of campylobacter fetus.the cellular fatty acid composition of 29 human and animal isolates of campylobacter fetus was determined with gas-liquid chromatography. all strains contained small amounts of 3-hydroxytetradecanoic acid, suggesting the presence of lipid a. each of 13 different blood or stool isolates of c. fetus subsp. jejuni obtained from humans or fowl contained a 19-carbon cyclopropane acid which was not present in c. fetus subsp. fetus (6 strains from cattle) or c. fetus subsp. intestinalis (10 strains fro ...19807381008
broiler chickens as potential source of campylobacter infections in humans.of 46 broiler chickens from a live poultry market in new york city, 38 (83%) harbored campylobacter fetus subsp. jejuni in their rectal flora. the observed mean number of c. fetus per g of feces was 4.4 x 10(6). the organisms survived in the feces for at least 96 h at 4 degrees c whether stored in the gut or transferred to a vial. the best survival medium for pure cultures of c. fetus subsp.jejuni was heart infusion broth supplemented with sterile blood and kept in a microaerophilic atmosphere.19807381018

antigens of campylobacter fetus subsp fetus eliciting vaccinal immunity in heifers.these studies were designed to identify the antigens of campylobacter fetus subsp fetus that elicit vaccinal immunity. heifers were vaccinated subcutaneously twice (42 days between vaccinations) with bacterins containing k, o, and h antigens (group a), o and h antigens (group b), or o antigen (group c) of the challenge strain. five heifers were not vaccinated and served as controls (group d). two weeks after heifers were given the second vaccination, the immunity of all heifers was challenge exp ...19807406293
[campylobacter fetus subspecies jejuni in chickens (author's transl)].a bacteriological examination of 239 chickens coming from 89 commerical flocks yielded a high incidence of campylobacter fetus subspecies jejuni isolations. from 30.1% of the birds or 41.6% of the flocks this micro-organism was isolated from 28.6% of the jejunal contents and 11.2% of the bile samples respectively. in contrast this agent could not be isolated from the skin or peritoneal cavity of 750 carcasses of broilers (13 flocks) before of after freezing in. no correlation could be found betw ...19807423469
an outbreak of acute enteritis due to campylobacter fetus subspecies jejuni at a nursery school of tokyo.an outbreak of acute enteritis due to campylobacter fetus subspecies jejuni involving a total of 35 out of 74 children occurred at a nursery school of tokyo in january 1979 and lasted for 7 days. it was the first case of a community outbreak of the disease to be recognized in japan. the major symptoms observed in the patients consisted of diarrhea (88%), fever (82%), abdominal pain (39%), and vomiting (6.1%). the rate of isolation of the organism from the patients was 39%. sera of four patients ...19807432196
campylobacter spp in enteric lesions in cattle.campylobacters were isolated from the intestinal mucosa of 16 of 47 cattle examined post mortem. of the 17 isolates seven were identified as campylobacter fetus subsp jejuni, eight as cf subsp intestinalis, one as c fecalis and one remained unidentified. cf subsp jejuni and cf subsp intestinalis were both recovered from one case. gross changes were not always seen at the sites from which campylobacters were isolated but microscopic changes were seen in all cases. the changes seen are described a ...19807434541
'1001' campylobacters: cultural characteristics of intestinal campylobacters from man and animals.the cultural characteristics of 1220 campylobacter strains from a variety of sources are described. forty-two were identified as campylobacter fetus ssp. fetus (véron & chatelain, 1973), 1120 as members of the c. jejuni/c. coli group, and 58 did not conform to any known description. sixteen of the latter strains had the basic characteristics of c. fetus but were atypical in certain other respects. the other 42 strains had the thermophilic characteristics of the jejuni/coli group, but were resist ...19807462593
hypocomplementemia and campylobacter fetus infection.a middle-aged alcoholic man had low c3 levels during two consecutive episodes of bacteremia with campylobacter fetus, with a return of c3 levels to normal during the interbacteremic period. total complement levels remained below normal throughout the patient's illness, whereas c4 and c3 activator values were in the normal or supranormal range. a rise and fall in hemagglutinating antibody titers, documenting an immune response, coupled with reasonable antimicrobial therapy were not sufficient to ...19807444533
campylobacter fetus ssp jejuni: isolation from patients with gastroenteritis.within a seven-month period, campylobacter fetus ssp jejuni was isolated in east tennessee from 18 patients with gastroenteritis; 83% of these patients had bloody diarrhea. absence of other enteric organisms such as salmonella, shigella, and yersinia implicated c fetus ssp jejuni as the causative agent. a fourfold increase in titer by tube agglutination from four of eight patients studied supported the pathogenicity of this organism. treatment with erythromycin alleviated gastroenteritis symptom ...19817466431
effect of moisture content of the medium on colony morphology of campylobacter fetus subsp. jejuni.reduction in the moisture content of the medium produced a profound effect on the colony morphology of campylobacter fetus subsp. jejuni. fresh medium produced flat, grayfish, spreading colonies with an irregular shape and variety appearance. plates that were incubated at 30 degrees c for 48 h produced round, convex, butyrous colonies with an entire edge. plates incubated at 30 degrees c for 24 h before inoculation produced colonies of an intermediate nature; they were round and raised, but not ...19817309853
the occurrence of campylobacter jejuni in fresh food and survival under different conditions.campylobacter jejuni was an almost regular finding in chickens and in minced meat from pigs and cattle sold in ordinary food stores. the bacteria survived on the food at 4 degrees c for one week and frozen at -20 degrees c for three months. none of the strains tested survived heat treatment at 60 degrees c for longer than 15 min. c. jejuni is apparently a frequent guest in most kitchens. correct food handling and heat treatment to at least 60 degrees c for 15 min should be enough to prevent infe ...19817310124
campylobacter fetus subsp. jejuni: experience in a large chicago medical center.from january 1979 through december 1979, 2069 stool specimens received by our laboratory for enteric culturing were additionally examined for the presence of campylobacter fetus subsp. jejuni. the study population included inpatients, outpatients and hospital food handlers. patients were included regardless of symptoms. enteric pathogens were identified as follows: salmonella, 27 isolates; campylobacter fetus subsp. jejuni, 26 isolates; and shigella, 11 isolates. twenty-five of 26 patients with ...19817315864
campylobacter fetus ss. jejuni, a newly recognized enteric pathogen: morphology and intestinal colonization.campylobacter fetus ss. jejuni has recently been recognized as a frequent enteric pathogen of man. although long known as a significant pathogen of domestic animals, little is known regarding mechanisms of colonization and pathogenesis. in an effort to study the colonization and morphology of this organism, we used scanning electron microscopy to examine ilea and colons from mice in which a human isolate of c. fetus ss. jejuni had been inoculated. when inoculated into the ileum of the mice, a tr ...19817347416
