| cellular fatty acid composition of campylobacter pylori from primates and ferrets compared with those of other campylobacters. | the cellular fatty acid profiles of newly described campylobacters were determined on a polar, capillary column. six isolates of the gastric spiral organism, campylobacter pylori subsp. mustelae, from ferrets from australia, england, and the united states were all found to have a similar fatty acid profile which was different from that of c. pylori from humans; c. pylori subsp. mustelae did not have 3-hydroxyoctadecanoic acid (3-oh c18:0) and had much less tetradecanoic acid (c14:0) and much mor ... | 1989 | 2745703 |
| in vitro binding of campylobacter jejuni surface proteins to murine small intestinal cell membranes. | surface proteins of nine campylobacter jejuni strains belonging to three different serovia were extracted with lysozyme/ethylenediamine-tetraacetic acid. the preparations bound to isolated murine small intestinal cells and to a membrane fraction (mf) of isolated brush borders obtained by detergent treatment with triton x-100 and nonidet p40. binding was demonstrated by an enzyme-linked immunosorbent assay procedure. using lipopolysaccharide (lps)- and flagella-specific antisera the contribution ... | 1989 | 2747590 |
| the use of cephalothin and triphenyltetrazolium chloride impregnated filter paper strips in the identification of campylobacter species. | filter paper impregnated strips using cephalothin at 30 and 60 micrograms/ml and triphenyltetrazolium chloride at 20 mg/ml were prepared and used in the typing of catalase-positive campylobacter species. there was no difference in the sensitivity of campylobacters to cephalothin at 30 micrograms/ml and 60 micrograms/ml. results were as reported by other workers except for a c. jejuni strain which was resistant to the triphenyltetrazolium. the technique is nevertheless inexpensive and the results ... | 1989 | 2748136 |
| cases of infective endocarditis caused by campylobacter fetus. | an 18-year-old man with infective endocarditis caused by campylobacter fetus is reported. this bacterial species has long been of interest in veterinary medicine, and recently it has been reported to be one cause of infantile diarrhea. infective endocarditis arising from campylobacter fetus is rare. this is the fourth case reported in japan. the organism was resistant to several antibiotics, and large vegetations were found to involve the aortic valve. emergency excision of the infected aortic v ... | 1989 | 2748151 |

| [campylobacter pylori. determination of gastric colonization and its clinical relevance]. | while evidence suggesting a statistical association between campylobacter pylori and chronic active antral gastritis is convincing, the role which the organism may play in the pathogenesis of this condition and in the case of peptic ulcer remains to be elucidated. the development of safe, non-invasive diagnostic tests suitable for population studies greatly facilitates this investigative process. this article presents a brief review of currently available methods of diagnosing c pylori colonizat ... | 1989 | 2749626 |

| 14c-urea breath test in c pylori gastritis. | 14c-urea breath test was used to detect campylobacter pylori colonisation in 129 consecutive non-ulcer dyspepsia patients. fasting patients were given 3 microci (110 kbq) of 14c-labelled urea after a test meal. breath samples were collected at 10 minute intervals for 90 minutes and the c-14 activity was counted on a liquid scintillation analyser. urea derived 14co2 appears in the exhaled breath of campylobacter pylori culture positive individuals within 20-30 minutes. likelihood analysis reveale ... | 1989 | 2753404 |
| the effect of cooling rate, freeze-drying suspending fluid and culture age on the preservation of campylobacter pylori. | the effects of freezing rate, suspending fluid and age of culture on the ability of four strains of campylobacter pylori to survive and recover from freeze-drying were examined. freeze-drying by standard procedures generally resulted in an overall loss in viability of between 3 and 7 log units. the exact cause of poor recovery by c. pylori was not established but strain differences were detected, with nctc 11637 (type strain) surviving better than nctc 11638 and nctc 11639. recovery of the poore ... | 1989 | 2753837 |
| a two-year study of the distribution of 'thermophilic' campylobacters in human, environmental and food samples from the reading area with particular reference to toxin production and heat-stable serotype. | the incidence of 'thermophilic' campylobacters in foods and environmental samples has been studied over a two-year period. of 781 environmental samples, 529 (67%) were found to contain campylobacters, and campylobacters were isolated from 835 (39%) of 2116 food samples. sewage was almost always contaminated with campylobacters (96.6% of samples) and of the food samples both poultry (55.5%) and offal (47.0%) were commonly contaminated. determination of the heat-stable serotypes of all strains iso ... | 1989 | 2753842 |
| enterotoxin production and serogroups of campylobacter jejuni and campylobacter coli from patients with diarrhea and from healthy laying hens. | enterotoxin production, a possible virulence factor, was determined in campylobacter jejuni and campylobacter coli by two different techniques, the cho cell test and the gm1 enzyme-linked immunosorbent assay. the frequency of enterotoxigenic campylobacter strains was 32% in strains from both humans with acute enteritis and healthy laying hens, as measured by the cho cell test. the cho cell test was significantly more sensitive than the gm1 enzyme-linked immunosorbent assay in the detection of en ... | 1989 | 2754001 |
| virulence of campylobacter jejuni for chicken embryos. | the pathogenicity of campylobacter jejuni was examined in chicken embryos. in this system, mortality data and histopathological findings induced by organisms and by bacterium-free filtered broth were identical. the absence in chicken embryo tissues both of organisms and of an inflammatory infiltrate suggests a toxin etiology. | 1989 | 2754005 |
| examination of human stomach biopsies, saliva, and dental plaque for campylobacter pylori. | to examine possible sources of campylobacter pylori and to determine the routes by which it is transmitted to the human stomach, samples of dental plaque and saliva from 71 patients undergoing endoscopy in addition to stomach biopsies were collected and cultured on selective noninhibitory skirrow medium. a total of 29 (40.8%) of the stomach biopsies yielded c. pylori. none of the saliva samples and only one of the dental plaque samples was found positive for c. pylori, and thus neither saliva no ... | 1989 | 2754008 |
| effects of sample holding time, temperature, and atmosphere on the isolation of campylobacter jejuni from dogs. | stool specimens were collected from 39 dogs, inoculated onto campylobacter blood agar plates, and divided into four subsamples. subsamples were held at 4 and 25 degrees c in room air and in a microaerobic environment and were reinoculated at 1, 2, 3, 4, 6, and 8 h. c. jejuni survived at least 3 h when it was held at 4 degrees c, but less than 2 h when it was held at 25 degrees c. the holding atmosphere was not associated with a difference in isolation rates. | 1989 | 2754014 |
| the relation between campylobacter pylori and inflammatory cell infiltration of antral mucosa in patients with dyspepsia. | in order to understand the relation between the prevalence of campylobacter pylori and the severity of gastritis, we conducted a survey of 166 randomly selected dyspeptic patients. the presence of c. pylori on the antral mucosa was aseptically determined by both urease and bacterial culture tests. specimens of antral mucosa were obtained for pathologic gradings of inflammation: active gastritis, mononuclear cell infiltration c0 (nil) to c3 (lymphoid follicle); presence or absence of intestinal m ... | 1989 | 2754423 |
| the presence of campylobacter pylori in nonsteroidal antiinflammatory drug associated gastritis. | although campylobacter pylori has recently been causally linked to active chronic gastritis and peptic ulcer disease, its relationship to nonsteroidal antiinflammatory drug (nsaid) associated gastritis is unclear. we performed a case-control study of 100 patients who had undergone gastritis biopsy. blinded review of giemsa stained slides demonstrated the presence of c. pylori in 32% of 19 nsaid treated cases with active chronic gastritis vs 3% of 36 controls with chronic gastritis not taking nsa ... | 1989 | 2754664 |
