Abstract Background and objectives: Helicobacter pylori is a Gram- negative bacteria causing diseases such as peptic ulcer and gastric cancer. In this research ,we determined the level of three types of antibody IgG, IgM and IgA in ordinary people of Izeh. Material and Methods: After collecting blood samples from 263 cases, the serum were obtaind and using the ELISA method the amount of IgG, IgM and IgA, against Helicobacter pylori measured. Results: Eleven samples(4.3%) out of 263 casese are positive for IgM anti-Helicobacter pylori. The frequency of IgA and IgG is 28(10.6%) and 201(76.4%),respectively. Conclusion: Based on results more than 70% of people in Izeh have Anti- Helicobacter pylori antibody in their serum, which is higher than that the other studied in Iran and also than developed countries.
