The bacterial load in gastric fluids from the non- and atrophic gastritis patients. A total of 5 ml gastric fluid was centrifuged and the precipitate was used for spreading blood agar, then microaerobically cultured for 4–7 days. There was a significant difference between N and S groups in the amount of (A) cultivable bacteria. Significant difference was also existed in the amounts of (B) bacterial DNA extracted from sample gastric fluids. The bacterial DNA was determined with UV-Vis at OD260, the amounts was calculated according to formula 1OD=50 µg/ml. *P<0.05.
