| failure of campylobacter pylori to grow in commercial blood culture systems. | of 50 blood culture sets, 20 bacto (difco laboratories, detroit, mich.), 20 septi-chek (hoffmann-la roche, inc., nutley, n.j.), and 10 bactec 6b and 7d (johnston laboratories, inc., towson, md.) sets were inoculated with campylobacter pylori and fresh human blood. none of the 50 blood cultures produced any detectable growth. current commercial blood culture systems may be inadequate for the detection of c. pylori bacteremia. | 1988 | 3384893 |
| characterization of urease from campylobacter pylori. | campylobacter pylori, a suspected agent of gastritis and peptic ulceration, rapidly hydrolyzes urea. because urease serves as the basis of detection of the organism in gastric biopsies and may represent an important virulence factor, biochemical characteristics of the enzyme were determined. c. pylori was isolated from antral biopsies from 10 patients with complaints of abdominal pain or history of peptic ulcer disease. all isolates were urease positive, with an average rate of hydrolysis by cel ... | 1988 | 3384908 |
| simple microbiologic detection of campylobacter pylori. | a study of 84 gastric biopsies taken from 42 adult patients revealed simple techniques for gram stain and culture for campylobacter pylori. in an initial study of 18 biopsies, gram stains prepared from ground, diluted tissue were all negative for curved, gram-negative rods, whereas 13 of these specimens were positive for c. pylori by culture. the gram stains for the remaining 66 biopsies were prepared by a rinse-imprint technique. in this group, there were 30 gram stains positive for organisms r ... | 1988 | 3384915 |

| immunoblot analysis of immune response to campylobacter pylori and its clinical associations. | systemic immune response to campylobacter pylori was detected by the immunoblot technique in serum samples from 200 patients, 129 blood donors, and 96 children. the results of the igg immunoblot test showed excellent correlation with the detection of c pylori by culture and also with histopathological examination of the antrum, as well as with peptic ulcer disease. an iga response also occurred and gave results comparable with those of the igg immunoblot test, although on a quantitatively lower ... | 1988 | 3384999 |
| cytotoxic activity in broth-culture filtrates of campylobacter pylori. | broth-culture filtrates of campylobacter pylori induced non-lethal cytopathic effects in vitro in 7 of 9 mammalian cell lines tested. transmission electronmicroscopy revealed that the response consisted of intracellular vacuolisation. intestine 407 cells were among the most responsive and were used for routine assay. about 55% of isolates of c. pylori tested, originating from four geographic regions worldwide, produced cytotoxic activity. the activity was neutralisable by specific antisera to br ... | 1988 | 3385767 |
| distribution of campylobacter pylori in the human stomach obtained at postmortem. | the distribution of campylobacter pylori, its prevalence, and its relationship to gastritis and urease activity have been studied in 54 postmortem stomachs. infection was confirmed by finding c. pylori in a gram-stained smear of gastric mucus harvested from the entire stomach. eight tissue specimens were obtained from predetermined sites from each stomach and examined for histologic gastritis and urease activity. thirty-seven per cent of stomachs were infected, and of these 80% had widespread hi ... | 1988 | 3387889 |
| campylobacter pylori in peptic ulcer disease. iii. symptoms and paraclinical and epidemiologic findings. | only a few publications have dealt with the subjective symptoms, the paraclinical findings, or the epidemiology in relation to cultivation of c. pylori. seventy-two patients answered a questionnaire containing questions about symptoms, dietary habits, smoking, and animal contact. c. pylori was cultivated from the biopsy specimens of 41 of these patients, and 31 were culture-negative. in addition, leukocyte count, differential count, and blood immunoglobulins were measured. in many culture-positi ... | 1988 | 3387900 |
| prevalence of campylobacter pylori in an unselected swedish population of patients referred for gastroscopy. | a survey of the prevalence of campylobacter pylori in an unselected series of 117 patients referred for gastroscopy showed that 49.6% of the patients were infected. in 87% of infected patients both the antrum and the body of the stomach were involved. duodenal infection occurred in only 9% of 102 studied patients. c. pylori could usually be demonstrated in mucosa showing signs of active chronic inflammation, whereas it was rarely found in histologically normal mucosa. the acridine orange stainin ... | 1988 | 3387901 |

| histological aspects of campylobacter pylori colonisation and infection of gastric and duodenal mucosa. | the main features of the histopathology of campylobacter pylori-associated gastritis are reviewed. the organism is strongly associated with the type b pattern of chronic gastritis. it colonizes the abnormal antrum and is not usually seen on the normal mucosa. however it fails to colonize the abnormal antrum in the type a gastritis of pernicious anaemia. when present in the duodenum it is in conjunction with severe duodenitis and gastric metaplasia. although the organisms are present in over 70% ... | 1988 | 3166530 |
| pathogenetic implications of ultrastructural findings in campylobacter pylori related gastroduodenal disease. | there is now substantial evidence that campylobacter pylori (cp) is able to colonize the gastroduodenal mucosa and is responsible for active chronic gastritis, its role in duodenitis, gastric ulceration and duodenal ulceration is still under debate. cp has a lot of characteristics which are prerequisites for a pathogen: the typical s-shape, the corkscrew-like movement and the powerful urease and protease enzymes. these features allow a rapid movement through the mucous layer to permit access to ... | 1988 | 3166531 |
| possible pathogenetic pathways of campylobacter pylori in gastro-duodenal disease. | the exact pathogenic mechanisms involved in campylobacter pylori associated gastro-duodenal inflammation are unclear. c. pylori adheres to gastric type epithelium and colonisation is associated with a number of ultrastructural abnormalities. other factors thought important include the marked bacterial urease activity, enzymatic degradation of the mucous layer and possible toxins. the induced inflammatory reaction will also contribute to tissue damage and a breakdown of normal defense mechanisms. | 1988 | 3166532 |
| immune response of the gastric mucosa to campylobacter pylori. | the histological features of non-autoimmune chronic gastritis are consistent with those of a local immune response by the gastric mucosa. if campylobacter pylori is causative in this condition, then the immune response will be in part specific for this organism. antibodies to c. pylori are present in the gastric juice of infected patients. coating of mucosal c. pylori by antibody in vivo can be demonstrated by immunohistochemistry, and a neutrophil infiltrate (active gastritis) is associated wit ... | 1988 | 3166533 |
| an enzyme-linked immunosorbent assay for the serodiagnosis of campylobacter pylori-associated gastritis. | an elisa system, using an acid extractable cell surface c. pylori antigen, has been used to detect anti-c. pylori antibodies in 176 endoscoped patients. the antibody concentration was related to histological diagnosis and colonisation with campylobacter-like organisms. the criteria for sero-positivity was determined from the median antibody concentration in a group of 368 non-endoscoped control patients. the specificity and sensitivity of the sero-diagnostic assay for histological gastritis in a ... | 1988 | 3166534 |
| prevalence of campylobacter pylori in duodenal and gastric mucosa--relationship to inflammation. | endoscopic biopsies from 310 patients were studied for the presence of campylobacter pylori (cp). in the first group of 150 patients duodenal and antral biopsies were obtained and in the second (160 patients) biopsies were taken from various sites in the stomach including the antrum, incisura, body and fundus. in the duodenum there was a strong association with active inflammation and the presence of gastric metaplasia. cp were never seen in the normal duodenum. in the stomach cp presence was as ... | 1988 | 3166535 |
| the efficacy of antimicrobial treatment in campylobacter pylori-associated gastritis and duodenal ulcer. | the efficacy of various antimicrobial and anti-ulcer agents on the elimination of campylobacter pylori in duodenal ulcer patients was investigated. ranitidine, cimetidine, pirenzepine, aluminium phosphate gel as well as combinations of h2-receptor antagonists or pirenzepine + penicillin v, ciprofloxacin, ofloxacin, phenyl-mercuryborate or rifampicin had no influence on c. pylori in vivo. short term elimination of c. pylori was achieved in 3/15 patients treated with ranitidine + bacampicillin and ... | 1988 | 3166537 |
| chronic erosive gastritis--a therapeutic approach with bismuth. | 37 patients with epigastric pain and chronic erosive gastritis underwent an open controlled therapeutic trial with bismuthsubsalicylate (bs). group a (21 patients) was treated with bs, liquid, 4 x 314 mg for three weeks, group b (16 patients) with bs tablets, 3 x 300 mg for two weeks. a significant reduction of symptoms (p less than 0.001) and endoscopically assessed chronic erosions (p less than 0.001) was achieved in both groups. campylobacter pylori was detected in 89% of the patients before ... | 1988 | 3166538 |
| epidemiology of campylobacter pylori infection: ethnic considerations. | a proper perspective of the association of campylobacter pylori with various diseases can be achieved only when the incidence of c. pylori infection in the normal population is known. we used the 13c urea breath test (a simple, specific, noninvasive, safe, and reproducible method to assess the presence of active c. pylori infection) to compare the frequency of c. pylori infection in healthy young adults from three areas of the world. we studied 26 women and 32 men (ages 20 to 29): 29 from the un ... | 1988 | 3166539 |
| pharmacokinetic, bacteriological and clinical aspects on the use of doxycycline in patients with active duodenal ulcer associated with campylobacter pylori. | seven patients with active duodenal ulcer and positive cultures for campylobacter pylori were given anti-ulcer treatment for 28 days with the addition of doxycycline for the last nine days. repeated endoscopy with biopsy for culture and doxycycline concentration determinations from the mucosa at the end of doxycycline therapy showed that five of seven patients remained positive in culture. the concentrations of doxycycline in biopsy material were 0.1 to 0.3 mg/kg in four patients; in three patie ... | 1988 | 3166544 |

| the urease enzymes of campylobacter pylori and a related bacterium. | the urease enzyme of campylobacter pylori was studied and compared with that of a related spiral-shaped bacterium, st1, isolated from the rodent ileum. both bacteria possessed constitutive urease enzymes with activities up to 20-70 times that of proteus vulgaris. this activity was retained on sds-polyacrylamide gels. a major catalytic subunit of mol. wt 300,000 was located for all (six) strains of c. pylori subjected to sds-page whereas st1 had two active forms of mol. wts 140,000 and 150,000. w ... | 1988 | 3172169 |
| isolation of a gastric campylobacter-like organism from the stomach of four rhesus monkeys, and identification as campylobacter pylori. | campylobacter-like organisms, isolated from the gastric antrum of rhesus monkeys, were compared with campylobacter jejuni and c. pylori. they were similar to c. pylori by light microscopy, in ultrastructural morphology, in enzymic, fatty-acid-methyl-ester, and protein-profile analysis, and in antigenic reactivity with rabbit antisera to c. jejuni and c. pylori and with c. pylori-specific monoclonal antibody. because this natural infection of the rhesus monkey is associated with chronic gastritis ... | 1988 | 3172170 |
| immunoblot fingerprinting of campylobacter pylori. | one hundred and fifty isolates of campylobacter pylori were divided into nine groups by immunoblot fingerprinting. all isolates were typable and reproducibility between immunoblots was good provided both antigen and antibody preparation were standardised. discrimination was a problem as groups 1 and 2 accounted for 66% of isolates. recurrence after bismuth treatment was due to indistinguishable strains in five patients and different strains in three patients. | 1988 | 3172174 |

| incidence of campylobacter pylori in patients with upper gastro-intestinal symptoms. | antral mucosal biopsy specimens were examined microbiologically and histologically for the presence of campylobacter pylori in 224 patients with upper gastrointestinal symptoms. the gastric mucosa of 183 patients (82%) were found to harbour c. pylori. c. pylori was strongly associated with the presence of histological gastritis (93%) and was detected in only 10% of 30 patients in whom histological examination of gastric biopsy specimens was negative. endoscopically diagnosed duodenal lesions wer ... | 1988 | 3194804 |
| prevalence of gastric metaplasia, inflammation, and campylobacter pylori in the duodenum of members of a normal population. | mucosal biopsies were obtained from 116 asymptomatic volunteers (50% were male; mean age, 46 years; age range, 19-91 years) to study the prevalence of duodenal gastric metaplasia (gm) and its association with inflammation and campylobacter pylori in a normal population. gm was identified in 25 subjects (22%). eighty-three subjects (72%) had histologic duodenitis, but in only 10 did the infiltrate include neutrophils (grade 2 duodenitis). c. pylori was found in the stomach in 36 subjects (31%), a ... | 1988 | 3195501 |
| distribution of campylobacter pylori and gastritis in the stomach of patients with and without duodenal ulcer. | the presence of campylobacter pylori and histological changes of gastric mucosa were studied in 50 consecutive patients with gastric complaints. c. pylori was isolated from the antrum, body, and fundus of 40 patients with (n = 20) and without (n = 20) duodenal ulcer. the incidence of gastritis was not significantly different in the antrum of c. pylori-positive patients with and without ulcer. otherwise, oxyntic mucosa of both body and fundus regions exhibited gastritis in 64.1% of the c. pylori- ... | 1988 | 3195542 |

| campylobacter pylori and barrett's esophagus. | campylobacter pylori is thought to be confined to gastric mucosa; when detected in the duodenum in association with duodenal ulceration, the organism infects only areas of gastric metaplasia. barrett's esophagus is a metaplastic condition of the esophagus, in which areas or islands of "gastric-type" epithelium are found. to determine whether c. pylori colonized the esophagus of patients with barrett's esophagus, we studied retrospectively 23 unselected patients who had endoscopic and biopsy evid ... | 1988 | 3199885 |
| campylobacter pylori and barrett's esophagus. | occurrence of c. pylori infection of mucosa outside of the stomach might provide an ideal opportunity to examine c. pylori-mucosal interactions apart from the effects of acid and pepsin. techniques previously used to examine barrett's epithelium (for example, special mucin stains or scanning and transmission electron microscopy) might be particularly useful for exploration of new associations and formulation of new hypotheses. whether c. pylori has a role in development of barrett's ulcer or ade ... | 1988 | 3199889 |
| the use of serology to diagnose active campylobacter pylori infection. | a serological test that predicts accurately active campylobacter pylori infection in the human stomach has been developed and validated by means of serum from 189 patients who were undergoing endoscopy in sydney. our enzyme-linked immunosorbent assay (elisa) has a sensitivity of 100% and a specificity of 94%. an important part of the test is the inclusion of a simple absorption step with c. jejuni for those sera whose results are close to the cut-off point for positivity. this has been shown to ... | 1988 | 3200186 |
| [campylobacter pylori colonization and gastroduodenal pathology]. | 355 patients suffering from dyspepsia with an endoscopic pathological picture were examined. campylobacter pylori was sought histologically and by culture. histological and cultural results were compared. there were no bacteria on the gastric mucosa of 46 patients who had no histopathological evidence of lesions. cultural studies were performed in 40 cases on endoscopic instruments used during the examination, before and after standard sterilization. campylobacter pylori was found on the gastric ... | 1988 | 3200472 |
| susceptibility of campylobacter pylori to macrolides and fluoroquinolones. | the in-vitro activities of several 14-, 15- and 16-membered macrolides and fluoroquinolones against campylobacter pylori were determined. in general, 14-membered macrolides, such as clarithromycin and flurithromycin, were more active than the 15-membered macrolide, azithromycin, which was more active than 16-membered macrolides, such as miocamycin and rokitamycin. fluoroquinolones, except ciprofloxacin and a-61827, were less active than macrolides. clarithromycin was the most active of the new c ... | 1988 | 3209524 |
| inhibitory antimicrobial concentrations against campylobacter pylori in gastric mucosa. | gastric mucosal concentrations of erythromycin, amoxycillin, ampicillin and ciprofloxacin were determined in patients at upper gastrointestinal endoscopy 38-480 min after a 500 mg dose of erythromycin ethyl succinate, erythromycin stearate, amoxycillin, pivampicillin or ciprofloxacin. all the agents attained concentrations greater than the mic 90 for campylobacter pylori. the macrolides attained the lowest concentrations. there was no significant difference between concentrations attained with e ... | 1988 | 3209531 |
