| serum antibody responses to the n-acetylneuraminyllactose-binding hemagglutinin of campylobacter pylori. | we recently reported that campylobacter pylori possesses a surface-associated fibrillar hemagglutinin which has an affinity for n-acetylneuraminyllactose; this hemagglutinin may function as a colonization factor for attachment to the gastric epithelium. in the present study we examined serum samples obtained from 65 c. pylori-infected individuals with gastric ulcers, duodenal ulcers, or both and from 121 asymptomatic volunteers, including 62 who were infected with c. pylori, for immunoglobulin g ... | 1989 | 2917777 |
| hemagglutination activity of campylobacter pylori. | forty-five strains of campylobacter pylori isolated from gastric biopsy specimens showed distinct hemagglutination activity. the activity was partially decreased by treatment with heat, trypsin, or an alkylating agent and was inhibited by porcine gastric mucin but not by various compounds, including d-mannose. | 1989 | 2917797 |

| in vivo susceptibility of campylobacter pylori. | campylobacter pylori infection has been associated with duodenal ulcer, gastric ulcer, and non-ulcer dyspepsia. although in vitro studies have shown that c. pylori is susceptible to most commonly used antibiotics, predictions from in vitro sensitivity studies have not led to a safe and generally effective therapy; c. pylori has proved to be very difficult to eradicate in vivo. we used the urea breath test to assess the susceptibility of c. pylori in vivo to various drugs. c. pylori was susceptib ... | 1989 | 2919580 |
| campylobacter pylori in esophagus, antrum, and duodenum. a histological and microbiological study. | two hundred forty-six patients with a wide range of upper gastrointestinal tract disorders were investigated for the presence of campylobacter pylori infection in esophagus, gastric antrum, and duodenum. c. pylori was identified in 52% of patients in at least one site, and microbiological and histological techniques were used to exclude the presence of the organism. esophageal infection was not significant and is probably due to reflux. antral c. pylori was significantly associated with active g ... | 1989 | 2920650 |
| campylobacter-like organisms and heterotopic gastric mucosa in meckel's diverticula. | to assess the possibility that campylobacter pylori might colonise heterotopic gastric mucosa a detailed histological review of 69 cases of meckel's diverticula resected over 17 years was undertaken. twenty three were resected incidentally while 46 were excised as the suspected cause of symptoms. gastric mucosa was found in 13 diverticula (19%), 10 from the symptomatic group and three from the incidental cases, of which eight showed active gastritis affecting the heterotopic mucosa. specific sta ... | 1989 | 2921353 |

| [assessment of methods of rapid diagnosis of campylobacter pylori in duodenal ulcers]. | a study of diagnostic value of the campylobacter pylori test as well as microbiological, bacteriological and biochemical findings in 134 patients with gastroduodenal ulcer and 20 healthy persons indicates that association of the campylobacter pylori and biochemical tests are reliable and may be recommended for wide use in practical public health. | 1989 | 2469254 |
| the association of campylobacter pylori with mucosal pathological changes in a population at risk for gastric cancer. | in the study of a group of 178 unselected patients (105 men, 73 women, mean age 44.5 years), from a population at high risk for gastric carcinoma, who presented with chronic dyspepsia, a minimum of 8 gastric and oesophageal biopsy specimens were taken during upper gastro-intestinal endoscopy, and examined histologically and histochemically for the presence of campylobacter pylori and other pathological lesions. gastric colonisation by c. pylori was found in 75% of men and 68.4% of women. in 90% ... | 1989 | 2470157 |
| colloidal bismuth subcitrate (de-nol) inhibits degradation of gastric mucus by campylobacter pylori protease. | there is increased awareness that infection with campylobacter pylori could be a major factor in the pathogenesis of gastric disease. here, we present evidence that the extracellular protease elaborated by this bacteria, which causes degradation of gastric mucus, is inhibited by an antiulcer agent, colloidal bismuth subcitrate (cbs; de-nol). the study was conducted with c. pylori cultured from antral mucosal biopsy specimens of patients undergoing gastroscopy. the grown colonies of bacteria were ... | 1989 | 2470250 |
| receptor-mediated adherence of campylobacter pylori to mouse y-1 adrenal cell monolayers. | an in vitro adherence assay was developed to study the adherence of campylobacter pylori to mammalian cells. strains of c. pylori were isolated from individuals with gastritis. these strains possessed the fibrillar n-acetylneuraminyllactose(neuraminlactose)-binding hemagglutinin (nlbh) and were found to adhere to monolayers of mouse y-1 adrenal cells. adherence was rapid, prevented by pretreatment of the y-1 cells with clostridium perfringens neuraminidase, and blocked by the neuraminlactose-con ... | 1989 | 2473033 |
| campylobacter pylori infection in biopsy specimens of gastric antrum: laboratory diagnosis and estimation of sampling error. | campylobacter pylori infection was sought in 382 consecutive patients referred for upper gastrointestinal endoscopy. five antral biopsy specimens were taken from each patient: one was inserted into a clo-test to detect the urease activity of c pylori, two were sent for histological analysis where multiple sections were stained by the warthin-starry silver method, and two were sent for microbiological evaluation by gram stain and culture. a patient was deemed to be infected when c pylori was cult ... | 1989 | 2474579 |
| [a method of determining campylobacter pylori in the gastric mucosa in peptic ulcer and chronic gastritis]. | an original method is described for the detection of campylobacter pylori in gastric mucosa biopsy specimens in chronic gastritis and gastroduodenal ulcers. the method is based on the detection (by a special test) of extremely high urease activity of c. pylori. the method has been employed in examinations of 211 patients. the results and prospects for the use of this technique for the detection of c. pylori in patients with gastroduodenal diseases are discussed. | 1989 | 2474707 |
| [detection of campylobacter pylori in children with chronic gastritis]. | examinations of the gastric mucosa biopsy specimens from 38 children suffering from chronic gastritis have revealed campylobacter bacteria in 21 (55.3%). studies of the cultural, morphologic, and biochemical characteristics of the isolated strains have identified them as c. pylori. | 1989 | 2474708 |
| comparison of rapid urease tests, staining techniques, and growth on different solid media for detection of campylobacter pylori. | thirty-nine single antral biopsies (phase 1) and 99 sets of six antral biopsies (phase 2) were collected from 132 patients, and 87 (63%) yielded positive cultures for campylobacter pylori. of several primary media tested in phase 1, tryptic soy agar and skirrow agar, each supplemented with 10% whole sheep blood, supported relatively good growth of c. pylori. in phase 2, four of the six biopsies in each set were tested with different urease systems. selective urea agar for rapid identification wa ... | 1989 | 2475524 |

| unusual features of helicobacter (campylobacter) pylori--associated gastritis in india. a study of 200 cases. | helicobacter (campylobacter) pylori has been cultured from the antral biopsies of 85-90% of patients of gastritis, gastric ulcer and duodenal ulcer at different centres. studies conducted all over the world have firmly implicated this organism in the aetiology of active superficial gastritis and recurrences of duodenal ulcer. two hundred patients with upper abdominal pain, distension, vomiting and/or haemetemesis were subjected to ogd scopy. in 163 of these patients there was endoscopic evidence ... | 1990 | 2092022 |
| association of peptic ulcer with helicobacter pylori and the recurrence rate. a three year follow-up study. | helicobacter pylori is associated with 70-100% of peptic ulcers. relapse of infection has been shown to cause recurrences of ulcers in a large number of studies. we diagnosed 137 cases of peptic ulcer (121 du; 16 gu) during a 3 year period. of these, 117 were positive for h pylori. sixty six of the 117 cases staying in the vicinity of the hospital were followed up for a minimum period of 3 months upto a maximum period of 3 years. in 91 examinations there was relapse of h pylori infection and ulc ... | 1990 | 2092024 |
| relapse of helicobacter pylori infection after different treatment regimens. a 3-month follow-up study. | helicobacter pylori infection of gastric antrum is associated with a majority of cases of peptic ulcer (70-100%). studies have shown that when this organism is eradicated, the recurrence of ulcer falls to less than one-third of those in whom the infection persists or relapses. monotherapy with bismuth salts, tinidazone or amoxycillin has been shown to result in early relapse and recurrence of ulcers. however, dual or triple therapy regimens are more effective. we conducted a randomised controlle ... | 1990 | 2092026 |
