| 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 |

| conservation and diversity of campylobacter pyloridis major antigens. | infection with campylobacter pyloridis has been strongly associated with gastritis in humans although its etiologic significance is currently undefined. we examined the structure and antigenicity of whole-cell, outer-membrane, acid-extractable surface protein, and proteinase k-treated whole cell lysate preparations from eight c. pyloridis strains by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting with homologous and heterologous immune rabbit serum. whole-cell and ou ... | 1987 | 3552997 |

| campylobacter pylori, the spiral bacterium associated with human gastritis, is not a true campylobacter sp. | comparison of partial 16s rrna sequences from representative campylobacter species indicates that the campylobacter species form a previously undescribed basic eubacterial group, which is related to the other major groups only by very deep branching. this analysis was extended to include the spiral bacterium associated with human gastritis, campylobacter pylori (formerly campylobacter pyloridis). the distance between c. pylori and the other campylobacter species is sufficient to exclude the pylo ... | 1987 | 3571163 |
| medium supplementation for growth of campylobacter pyloridis. | experiments were conducted to define the growth requirements of campylobacter pyloridis, a newly discovered organism associated with gastritis and peptic ulcers. two clinical isolates were streaked onto various media, and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. the growth obtained on fresh chocolate agar, composed of gc agar base (difco laboratories, detroit, mich.) plus 1% hemin, was used as a reference. the organism grew ... | 1987 | 3571466 |

| campylobacter pyloridis in peptic ulcer disease. i. gastric and duodenal infection caused by c. pyloridis: histopathologic and microbiologic findings. | in this study 153 patients with dyspepsia were biopsied in the gastric antrum and duodenum. all specimens were investigated histopathologically and microbiologically for the presence of campylobacter pyloridis, and the type of inflammation was recorded in accordance with morson's criteria. c. pyloridis was found beneath the mucus close to the epithelial cells and mostly in connection with granulocytic infiltration (active gastritis). c. pyloridis was cultured from all of 10 patients with histolo ... | 1987 | 3576129 |
| campylobacter pyloridis degrades mucin and undermines gastric mucosal integrity. | the role of campylobacter pyloridis, a spiral bacteria associated with gastritis and peptic ulcers in weakening the mucus component of gastric mucosal barrier was investigated. the colonies of bacteria, cultured from antral mucosal biopsies of patients undergoing gastroscopy, were washed with saline, passed through sterilization filter and the filtrate was examined for protease and glycosylhydrolase activities. the obtained results revealed that the filtrate exhibited a strong proteolytic activi ... | 1987 | 3579908 |
| "campylobacter pyloridis" and epigastric pain: endoscopic, histological, and bacteriological correlations. | campylobacter pyloridis is a newly discovered bacterium which has been implicated in gastric pathology. c. pyloridis was looked for by hematoxylin and eosin staining and culture (chocolate and brucella blood agar) in gastric antral biopsies in 136 unselected patients suffering from epigastric pain. the distribution of c. pyloridis positive cases according to the endoscopic diagnosis was as follows: duodenal ulcer (19 positive/21 tested), duodenitis (6/10), gastric ulcer (9/21), gastritis (13/26) ... | 1987 | 3582869 |
| interaction of campylobacter pyloridis with human immune defence mechanisms. | the in-vitro susceptibility to host immune defence mechanisms of campylobacter pyloridis was investigated. c. pyloridis was sensitive to antibody-dependent complement-mediated bactericidal activity of serum. the bacteria were phagocytosed and efficiently killed by polymorphonuclear neutrophils in the presence of serum opsonins. serum opsonin depletion studies indicated that an intact classical complement pathway was required for optimal phagocytic killing. | 1987 | 3585959 |
| association of campylobacter pylori on the gastric mucosa with antral gastritis in children. | we investigated the presence of campylobacter pylori colonization of the gastric mucosa and of histologic evidence of gastritis in a prospective study of 71 consecutive children undergoing upper gastrointestinal tract endoscopy and gastric biopsies because of gastrointestinal symptoms. two tissue samples from the gastric antrum were obtained from 67 of the 71 children (mean age [+/- sd], 11.4 +/- 3.8 years). one sample was evaluated for evidence of gastritis and stained with silver to detect org ... | 1987 | 3587289 |
| in vitro susceptibility of campylobacter pyloridis to cimetidine, sucralfate, bismuth and sixteen antibiotics. | the in vitro susceptibility of recent danish human clinical isolates of campylobacter pyloridis to cimetidine, sucralfate, bismuth subsalicylate and sixteen antimicrobial agents was determined by an agar-dilution technique. benzylpenicillin was the most active drug (mic90 = 0.1 microgram/ml); ampicillin, erythromycin, gentamicin and ciprofloxacin were slightly less active. all strains were resistant to 100 micrograms sulfamethizole, and nalidixic acid also had little activity on weight basis. of ... | 1987 | 3591312 |
