| evaluation of cultural techniques for isolating campylobacter pyloridis from endoscopic biopsies of gastric mucosa. | one hundred and three gastroscopic biopsies from 80 patients were cultured for campylobacter pyloridis and studied histologically. active chronic gastritis, as shown by the presence of polymorphonuclear leucocytes, was diagnosed in 51 biopsies and c pyloridis was found in 47. sixteen gastric biopsies showed normal histology (no inflammation); c pyloridis was detected in only one of these, and a second biopsy taken from this patient at the same time showed active gastritis. biopsies could be kept ... | 1985 | 3902897 |
| [campylobacter in gastric pathology]. | the incidence of campylobacter pyloridis in the stomach of patients with chronic gastritis, peptic ulceration and in normal subjects, has been studied. seventy-one biopsy specimens were taken from affected and normal gastric mucosa of 61 patients and 10 normal subjects, respectively. in 54 (88.5%) out of the 61 patients and in 1 (10%) out of the 10 normal subjects, c. pyloridis was observed. in addition, in 39 samples this microorganism was successfully cultured. | 1985 | 3916977 |
| unusual cellular fatty acids and distinctive ultrastructure in a new spiral bacterium (campylobacter pyloridis) from the human gastric mucosa. | spiral bacteria, named campylobacter pyloridis, were obtained from endoscopic biopsies of the gastric antrum of 14 patients with active chronic gastritis. methyl esters of their cellular fatty acids were prepared by acid-catalysed transmethylation of whole cells. their major fatty acids were tetradecanoic acid (14:0) and cis-9,10-methyleneoctadecanoic acid (19:0 delta), with a very small amount of hexadecanoic acid (16:0). this is markedly different from the fatty acids of other campylobacter sp ... | 1985 | 3981612 |
| campylobacter pyloridis in peptic ulcer disease: microbiology, pathology, and scanning electron microscopy. | after the recent successful isolation of spiral organisms from the stomach this paper presents the bacteriological and pathological correlation of gastric antral biopsies from 51 patients endoscopied for upper gastrointestinal symptoms. campylobacter pyloridis was cultured from 29 patients and seen by either silver staining of the biopsy or scanning electron microscopy in an additional three. the organism was cultured from 23 of the 33 (69%) patients with peptic ulcer disease and from within thi ... | 1985 | 4065695 |
| characterization of "campylobacter pyloridis" by culture, enzymatic profile, and protein content. | "campylobacter pyloridis" has been recently described as a gastritis-associated bacterium. we studied 20 strains. the bacteria had most of the characteristics of campylobacter spp. strains. they were hippurate negative and tolerant to triphenyl tetrazolium chloride (at 0.4 and 1 mg/ml). they grew on all the media commonly used in laboratories, although chocolate agar was the most effective for isolation. they grew in a microaerophilic atmosphere as well as in an atmosphere enriched in co2 and wh ... | 1985 | 4066910 |

| [novel characteristic of the genus campylobacter: campylobacter-like organisms]. | the first report of human infections due to campylobacter dates back to 1947. these microorganisms, classified initially as vibrio, had been known for many years as agents of several diseases in animals. in 1963 they were grouped in the new genus campylobacter belonging to spirillaceae. campylobacter are ever more important, particularly c. jejuni, which is an ubiquitous agent of diarrhoea in children. other microorganisms of this genus, the "gastric campylobacter-like organisms" type i, otherwi ... | 1986 | 3331155 |
| clinical importance of campylobacter pyloridis and associated serum igg and iga antibody responses in patients undergoing upper gastrointestinal endoscopy. | campylobacter pyloridis was isolated from 77% of 220 (35%) unselected adults undergoing gastroscopy. isolation was significantly associated with histological gastritis (p less than 0.0001), duodenal ulcer (p less than 0.0001), and to a much lesser extent, with gastric ulcer (p less than 0.05). the relation between the isolation of c pyloridis and peptic ulcer seemed to be independent of coexisting gastritis. in those with no endoscopic or histological evidence of disease there was no relation be ... | 1986 | 3950046 |
| campylobacter pyloridis and gastritis: association with intercellular spaces and adaptation to an environment of mucus as important factors in colonization of the gastric epithelium. | stomach biopsy specimens from greater than 40 individuals with campylobacter pyloridis-associated gastritis were examined by light and electron microscopy. the bacteria were consistently seen in two locations: within the gastric mucus and associated with intercellular junctions of gastric epithelial cells. c. pyloridis is suggested to be one of a broad group of spiral bacteria that are adapted to the peculiar niche provided by intestinal mucus. the spiral morphology and the form of motility of t ... | 1986 | 3950447 |
| relation of campylobacter pyloridis to gastritis and peptic ulcer. | biopsy specimens from the gastric antral mucosa of 50 patients with upper gastrointestinal complaints were studied by light and electron microscopy and culture. of 46 assessable specimens, seven were histologically normal, and 39 showed evidence of gastritis. twenty-seven of the specimens with evidence of gastritis (69%) contained spiral bacteria, whereas only one of the normal specimens (14%) contained these bacteria (p = .02). of 17 patients found to have gastric ulcers, 10 (59% [p greater tha ... | 1986 | 3950448 |

| susceptibility of campylobacter species to metronidazole, its bioactive metabolites and tinidazole. | the susceptibilities of 115 campylobacters, belonging to five species, to metronidazole, its principal oxidative metabolites and tinidazole were determined by an agar dilution method. the activities of metronidazole and tinidazole were comparable. the hydroxy metabolite was more active than the parent drug against most species, particularly campylobacter jejuni and campylobacter pyloridis. although the acid derivative was less active against c. jejuni and campylobacter coli, it demonstrated an e ... | 1987 | 3436679 |
| isolation of campylobacter pyloridis from human gastric mucosa and characterization of the isolates. | biopsy specimens of human gastric mucosa of patients with gastric complaints and subjected to endoscopic examination were cultured microaerobically, and campylobacter pyloridis was detected in 46 out of 80 cases (57.5%). the organism was found in 13 out of 22 patients with gastritis, 11 out of 16 with gastric ulcer scar, 7 out of 16 with gastric ulcer, 3 out of 9 with gastric polyp, 4 out of 5 with gastric carcinoma, 2 out of 2 with esophagus carcinoma, and 6 out of 9 with other gastric diseases ... | 1987 | 3437827 |
| frequency of occurrence of campylobacter pylori and analysis of the systemic and local immune response. | during gastroduodenoscopic examination of 225 patients, bioptic mucosal specimens were taken for bacteriological and histological examination (table 1). campylobacter (c.) pylori was isolated from 7 out of 9 patients (78%) with gastric ulcer, from 59 out of 60 (98%) with duodenal ulcer, from 24 out of 31 (77%) with gastric erosions, from 10 out of 10 (100%) with duodenitis, from 14 out of 16 (88%) with chronic active gastritis, from 40 out of 73 (55%) with chronic inactive gastritis and from non ... | 1987 | 3439387 |
| [campylobacter pyloridis and socioeconomic levels]. | the purpose of this study was to determine if there was any relationship between the socio-economic level of patients and the colonization of the stomach by campylobacter pyloridis. we have studied 256 patients who underwent esophagogastroduodenoscopy because they had upper gastrointestinal symptoms of this group, 143 from arzobispo loayza hospital (38 males and 105 females) and 122 from the private practice of three of the authors (77 males and 45 females). the ages ranged from 16 to 75 years ( ... | 1987 | 3442181 |
| [campylobacter pyloridis and gastritis: endoscopic, histological and microbiological correlations]. | biopsy specimens from antral mucosa in 65 consecutive patients presenting for gastroscopy were assessed histologically and microbiologically for the presence of c. pyloridis. spiral bacteria were found in 63% of cases by warthin-starry silver stain and in 72% by culture on blood agar plates with skirrow's antibiotic supplement. a significant association between the occurrence of c. pyloridis and chronic gastritis was noted; the association is not influenced by the type of gastritis, superficial ... | 1987 | 3449100 |

| campylobacter pyloridis in the upper gastrointestinal tract: a brazilian study. | the successful isolation of c. pyloridis from human gastric mucosa has renewed interest in these bacteria and their role as a causative agent for gastritis, and possible causal relationship between chronic gastritis and peptic ulceration. to determine the incidence of c. pyloridis in gastric biopsies we studied 51 consecutive brazilian patients with a wide range of alimentary disorders presenting for endoscopy. at least three biopsies were taken from each site: antrum, any ulcer or cancer. micro ... | 1987 | 3450271 |
| rapid urease test in the management of campylobacter pyloridis-associated gastritis. | campylobacter pyloridis colonization of the stomach may be an etiological factor in gastritis and peptic ulceration. campylobacter pyloridis produces large amounts of urease, and the presence of this enzyme in gastric mucosa usually indicates infection with the organism. in this paper we describe the use of a rapid urease test (clotest) to detect c. pyloridis infection in gastric mucosal biopsies. in 141 consecutive endoscopy cases, antral biopsies were taken for culture and histology, and an ex ... | 1987 | 3548326 |

| [bacterial colonization of the gastric mucosa]. | in 380 histologically prepared biopsy specimens taken from the mucous membrane of the stomach, the employment of giemsa staining and warthin-starry silver staining has revealed an often surprisingly abundant (i. e., to the extent of 66.1%) bacterial colonization of the surface of the gastric mucous membrane and of the gastric foveolae. the bacteria encountered here involve gram-negative and morphologically uniform flora of thin, s-shaped or slightly curved bacteria designated as campylobacter-li ... | 1987 | 3551359 |
| campylobacter pyloridis gastritis: the past, the present, and speculations about the future. | campylobacter pyloridis infection of the stomach has been associated with gastric ulcer, duodenal ulcer, nonulcer dyspepsia, and gastritis. the etiological role of c. pyloridis in most of those conditions remains unclear. we reviewed what is known about c. pyloridis infections in man. considerable clinical data on c. pyloridis infections was available in older literature concerning gastritis and gastric urease. c. pyloridis causes a form of type b gastritis. in some individuals the acute infecti ... | 1987 | 3551584 |
