Abstract: AIM: To detect antibodies against Helicobacter pylori spiral and coccoid antigens in human sera. METHODS: Blood samples were collected from 278 patients with gastric diseases. A 3-day-old culture of H. pylori on chocolate blood agar was used to provide spiral form. 'Synchronous' coccoids were cultured in (BHY) (brain heart infusion supplemented with 10% horse serum and 0.4% yeast extract) medium in a chemostat. Antigens from spiral and coccoid form were prepared using acid glycine extraction. Enzyme-linked immunosorbent assay (ELISA) was performed to detect serum IgG antibodies against spiral and coccoid forms of H. pylori. RESULTS: Seroprevalence of H. pylori infection was higher in patients with gastric ulcer (79%) and gastric cancer (83%) than those with non-ulcer dyspepsia (NUD) (44%) and other diseases (45%) (P
