OUTBREAK OF cagA AND iceA IN H. PYLORI STRAINS ISOLATED FROM PATIENTS WITH GASTRO DUODENAL DISEASES IN BABOL CITY

BACKGROUND AND OBJECTIVE: Helicobacter pylori is one of the most common bacteria that afflicts world’ human population. Virulence factor of Helicobacter pylori have been associated with clinical outcome of the infection including gastritis, gastric ulcer (GU), duodenal ulcer (DU) and gastric cancer....
