| properties of crude campylobacter jejuni heat-labile enterotoxin. | the amount of crude campylobacter jejuni enterotoxin present in culture products was quantitated by comparing the response of these preparations with that of pure escherichia coli heat-labile toxin (lt) in the chinese hamster ovary assay and in enzyme-linked immunosorbent assays that used gm ganglioside or antisera to lt or both. maximum c. jejuni enterotoxin production was achieved by growth at 42 degrees c for 24 h under agitation in supplemented gc medium. adding polymyxin separately to eithe ... | 1984 | 6746090 |
| systematic investigation of enrichment media for wild-type campylobacter jejuni strains. | of the media examined, thioglycolate broth supplemented with 5% lysed sheep blood, butzler antibiotic mixture, and 0.1% lauryl sulfate was the most sensitive enrichment medium for recovery of wild-type strains of campylobacter jejuni from cecal contents of chickens and chicken livers. it allowed the retrieval of 1 cfu as did solid media but permitted the screening of 50-times larger volumes. double-strength enrichment medium required 5 to 10 cfu for growth. omission of lauryl sulfate reduced the ... | 1984 | 6746890 |
| antibiotic sensitivity patterns of campylobacter jejuni/coli isolated from laboratory animals and pets. | fifty-four strains of campylobacter jejuni/coli isolated from a variety of species of laboratory animals as well as pet dogs were tested by an agar dilution technique for susceptibility to each of 12 antimicrobial agents. gentamicin and furazolidone were the most active of the drugs examined. the strains tested frequently were sensitive to two other aminoglycoside antibiotics, neomycin and kanamycin. erythromycin also was effective at levels achievable in serum except in three strains which were ... | 1984 | 6748605 |
| comparative studies on competitive exclusion of three isolates of campylobacter fetus subsp. jejuni in chickens by native gut microflora. | resistance of young chicks to campylobacter fetus subsp. jejuni was substantially increased by early exposure to native gut microflora. protection was demonstrated against two human isolates and a chicken isolate of c. fetus subsp. jejuni. significant protection against the chicken isolate was observed throughout a 91-day test period. infection reached 100% (25/25) in the untreated group at 56 days of age and only 4% (1/25) in the group treated with native gut microflora. campylobacter fetus sub ... | 1984 | 6721792 |
| campylobacter jejuni infections in haifa subdistrict, israel, summer 1981. | a study investigating the clinical and epidemiological characteristics of campylobacter jejuni infections in an urban community in israel is presented. most of the information was obtained by interviewing 76 patients who constituted a systematic sample out of a total of 215 patients suffering from acute campylobacter jejuni diarrhoea during the summer of 1981. the crude annual incidence rate was 17 per 10 000. age-specific incidence rate in infants up to one year of age was eight times higher th ... | 1984 | 6735568 |

| campylobacter jejuni associated diarrhea in commercially reared beagles. | campylobacter jejuni was isolated from nine of ten (90%) juvenile beagles with diarrhea, compared with an isolation rate of five of eight (63%) from beagles which remained asymptomatic during the 2 month study. in four dogs, the diarrhea was recurrent and characterized by watery, mucoid, bile-streaked feces with occasional blood. elevated temperature and leukocytosis were noted in three of these dogs. two dogs with diarrhea also had giardia canis trophozoites. | 1984 | 6727288 |
| the ability of campylobacter media supplements to neutralize photochemically induced toxicity and hydrogen peroxide. | nutrient agar plates stored in light and air for 48 h became inhibitory for campylobacter jejuni, c. coli and nalidixic acid-resistant, thermophilic campylobacter (nartc) strains. all five campylobacter test strains showed greater than 5 log reduction in counts on media which had been stored in light and air. media stored in the dark and/or in a reduced atmosphere did not become inhibitory and supported the growth of campylobacters. ferrous sulphate, sodium pyruvate, blood, charcoal or sodium me ... | 1984 | 6706882 |
| abortion in the dog due to campylobacter species. | campylobacter jejuni was isolated from a wheaten terrier bitch which had aborted (in southern idaho). a campylobacter of undetermined species also was isolated from aborted poodle pups (in central washington). it appears that persons may have been the source of infection in the idaho event, but the source for the other was not speculated. these findings of perinatal death due to campylobacter in dogs from widely separated areas indicate that pathologic evaluation of cases involving premature and ... | 1984 | 6711985 |
| association of campylobacter jejuni with laying hens and eggs. | laying hens were individually caged at 20 weeks of age and tested for fecal excretion of campylobacter jejuni (minimum level of detection was 100 cfu/g) during a 42-week period. peak rates of c. jejuni isolation (approximately 25% of hens positive) occurred at two different times, in october and in late april to early may. before being segregated in late september, birds were allowed to consume fecal matter, litter, and communal drinking water, all likely sources of c. jejuni. the increased excr ... | 1984 | 6712220 |

| reversible expression of flagella in campylobacter jejuni. | campylobacter jejuni 81116 and a3249 undergo a bidirectional transition between flagellated (fla+) and aflagellated (fla-) phenotypes. when measured in culture medium, the fla+----fla- transition occurred at a rate of 3.1 x 10(-3) to 5.9 x 10(-3) per cell per generation, and the fla- to fla+ transition occurred at a rate of 4.0 x 10(-7) to 8.0 x 10(-7) per cell per generation. however, passage through a rabbit intestine markedly favored the fla+ phenotype. | 1985 | 4066041 |
| epidemiologic and laboratory investigation of an outbreak of campylobacter enteritis associated with raw milk. | an outbreak of gastroenteritis occurred in march-april 1981, in wichita, kansas, and involved more than 250 persons who drank raw milk from a single local dairy. campylobacter jejuni was recovered from 60 of 116 (52%) persons in households that had one or more ill family members. a cohort study of families that belonged to a food cooperative that purchased raw milk from the implicated dairy showed a significant association between illness and having drunk raw milk. thirty-nine of 55 (71%) person ... | 1985 | 4050775 |
| motility as an intestinal colonization factor for campylobacter jejuni. | the colonization of the intestinal tract of suckling mice by campylobacter jejuni was examined by orally challenging the mice with a wild-type strain and several nonmotile mutant strains which were isolated after treating the wild-type strain with mutagens. the wild-type strain had colonized the lower portion of the small intestine, the caecum and the colon 2 d after inoculation. two nonmotile strains, one of which (m8) had lost all the flagellar structure including the filament, the hook and th ... | 1985 | 4056739 |
| chemically defined media for auxotyping of campylobacter jejuni. | a set of chemically defined media has been developed for the cultivation of campylobacter jejuni strains of human origin. a minimal medium, a complete medium and 5 different nutrient-deficient media (ndm1-ndm5) are described. some of the strains investigated required l-methionine(lacking in ndm1), l-cystine and l-cysteine (ndm2), k2hpo4 (ndm 3), kh2po4 (ndm4) and nad, thiamine and calcium pantothenate (ndm5). 57.7% of the strains investigated required l-methionine. the strains grew at ph 6.6-7.7 ... | 1985 | 4060921 |
| role of litter in the transmission of campylobacter jejuni. | autoclaved or non-autoclaved used broiler litter that was experimentally contaminated with campylobacter jejuni was capable of infecting specific-pathogen-free chicks maintained in modified horsfall isolators. artificially infected chicks became fecal shedders of c. jejuni, resulting in contamination of both autoclaved and non-autoclaved used broiler litter. fecal shedding of c. jejuni by litter-reared, artificially infected chicks persisted for at least 63 days after chicks were transferred to ... | 1985 | 4026733 |
| campylobacter colitis: histological immunohistochemical and ultrastructural findings. | the colonic biopsy specimens of 22 patients with colitis and positive stool cultures for campylobacter jejuni were studied in order to obtain histological and immunohistochemical criteria to differentiate campylobacter colitis from chronic inflammatory bowel disease. in addition we tried to identify campylobacter inclusions by means of immunohistochemistry and electron microscopy as evidence for invasion of the colonic mucosa. the results show that the majority of patients with campylobacter col ... | 1985 | 4029720 |
| experimental infection of hamsters with campylobacter jejuni. | campylobacter jejuni is a major cause of diarrhea and enterocolitis in humans and animals. a mammalian model has been developed for studying pathogenesis of the disease in hamsters by colonizing the ileum and cecum with c. jejuni via either oral intubation after purgation or direct surgical inoculation into the cecum. this colonization resulted in production of disease including diarrhea and intestinal lesions that resembles enterocolitis due to c. jejuni in humans and domestic animals. the muco ... | 1985 | 4038721 |
