Abstract
Susceptibility to the following antibiotics [Ampicillin (10µg), Erythromycin (15µg), Amoxycillin (10µg), Rifadin (30µg), Tetrayclin (30µg), Penicillin (10µg) and Metronidazle (5µg) ] of 50 clinical isolates of Helicobacter pylori from despotic patient was determined by Kirby and Bauer method which modified by Vandepitte. Helicobacter pylori isolates showed the highest sensitivity to Amoxycillin. And failure of identication of Helicobacter pylori was noted in patient who had been treated with Amoxycllin, Metronidazole, Cimetidine and Antacid in 92.9%. This study also revealed that the patient who had not received proper antibiotics, the gastritis resulting from Helicobacter pylori can lead to a more serious conditions like gastric, duodenal and esophageal ulceration's in a rate of 100%.
