The Role Of Outer Inflammatory Protein A (Oipa) In Vaccination Of Thec57bl/6 Mouse Model Infected By Helicobacter Pylori, Mohaddese Mahboubi, Tahereh Falsafi, Majid Sadeghizadeh, Fatemeh Mahjoub

Turkish Journal of Medical Sciences

Background/aim: Outer inflammatory protein A (OipA) is an important adhesin of Helicobacter pylori. Our goal was to assess the role of OipA in protection of C57BL/6 mice against H. pylori. Materials and methods: C57BL/6 mice were mucosally immunized with recombinant OipA protein, OipA + propolis, propolis, and phosphate-buffered saline. After vaccination, anti-OipA IgA was measured. Mice were challenged three times with 5 x 107 CFU of the H. pylori B19 strain. Two weeks later, bacterial colonization and inflammation in the stomach was analyzed using standard methods. Results: The CFU number in the OipA group was significantly (P < 0.05) lower than that of the control. The CFU number in the OipA + propolis group was higher than those of the OipA and propolis groups. IgA titers were significantly higher (P < 0.0001) in the OipA group compared to the control and OipA + propolis groups. Propolis did not play an adjuvant effect but it interfered with the efficient vaccine effect of OipA. Conclusion: Results show the effect of vaccination by OipA in protection of the mouse model and the importance of OipA in H. pylori pathogenesis. OipA may be proposed as a suitable oral vaccine candidate against H. pylori infection; however, further study is required to determine adjuvant or adverse effects of propolis toward OipA.

Helicobacter Pylori: Types Of Diseases, Diagnosis, Treatment And Causes Of Therapeutic Failure, Cosmin Vasile Obleaga, Cristin Constantin Vere, Ionica Daniel Valcea, Mihai Calin Ciorbagiu, Emil Moraru, Cecil Sorin Mirea

Journal of Mind and Medical Sciences

Acute upper gastrointestinal lesions have a multifactorial etiology but, regardless of the cause, they are related to mucosal barrier destruction. Since Helicobacter pylori induces a superficial chronic gastritis with the infiltration of neutrophils in the mucosa, it was speculated that Helicobacter pylori infection could also cause bleeding lesions. The diagnosis, the proper treatment and the revaluation of its effectiveness actually represent the prophylaxis of some diseases such as peptic ulcer, gastric lymphoma or mucosa-associated lymphoid tissue (MALT) and gastric cancer. These diseases and their severe complications are life-threatening for the patient. Periodic renewal of the treatment and knowing the real …

Jurnal Penyakit Dalam Indonesia

Introduction. Helicobacter pylori (H. pylori) infection risk is associated with many factors related to host-agent-environment. Ethnicity is one of the host factors which was the most studied factor overseas. The prevalence of H. pylori infection was found higher in certain ethnic such among Chinese. Based on migration and transmission theory, it was suspected that H. pylori infection was transmitted by people migrating from areas with a high prevalence of infection to the destination area. Chinese in West Borneo are originated from South China region where the prevalence of H. pylori infection is high. It is estimated that there are differences …
