Gastric adenocarcinoma is of major importance worldwide as a cause of death frommalignant disease. It is the commonest malignant tumor in T.U. Teaching Hospital.Helicobacter pylori infection is an important risk factor for the development of gastriccancer. This prospective study was carried out to correlate H. pylori infection withgastric adenocarcinoma. This study was done from January 1999 to January 2000;included 38 cases of gastric adenocarcinomas of which 28 (73.69%) cases were tubulartype; 6 (15.79%) cases were signet-ring cell type; 2 (5.26%) cases were papillary typeand 2 (5.26%) cases were mucinous type. Gastric adenocarcinomas were more commonin male (73.68%) and after the age of 50 years. Giemsa staining revealed H. pylori in30 cases (78.95%) of adenocarcinomas; whereas H. pylori seropositivity (IgG) wasfound in 29 (76.31%) cases. H. pylori were histologically detected in 88.3% cases ofresected specimens and in 71.4% cases of endoscopic gastric biopsies. Both histologicalmethod and serological test showed positivity for H. pylori in 65.78% cases. Thus, H.pylori infection is associated with gastric carcinognesisKey Words: Gastric adenocarcinoma, Helicobacter pylori, Giemsa stain.

Helicobacter pylori is a microaerophilic, gram-negative bacterium found in the upper gastrointestinal tract of humans. There is strong evidence that H. pylori is important in the etiology of gastritis; the bacterium may also be a major predisposing cause of peptic ulceration. On the gastric mucosa, the organism exists as a spiral form with one to seven sheathed flagella at one (usually) or both poles. Short spirals were seen in the first successful culture of the organism in 1983. In 1984, Marshall and Warren reported a coccoid form in older cultures. Since that time, other workers have observed rod and coccal forms in vitro; coccoid forms predominate in cultures 3-7 days old. We sought to examine the growth cycle of H. pylori in prolonged culture and the mode of coccoid body formation.
