5. During fibergastroscopy a patient with ulcer disease of the stomach, the mucosal biopsy is taken from the area of an ulcer. Impression smear is prepared from biopsy material and stained by Gram method; the rest of biopsy material is tested for urease activity.

A. Helicobacterial infection B. Dietary allergy
C. Autoantibody production
D. Reduced prostaglandin synthesis
E. Disorder of gastric motor activity
7. In order to prevent wound infection associated with surgical procedures a patient was given a synthetic antiprotozoan drug with a high activity against Helicobacter pylori. Specify this drug:
