    Abstract:
    Campylobacter pylori has been cultured from 85-90% of antral biopsies of patients of gastritis, duodenal ulcer and gastric ulcer at different centres in the world. It has been now firmly implicated in the aetiology of active gastritis as well as suspected to cause repeated recurrences of peptic ulcers. However, the organism is very fastidious and is difficult to grow by standard culture methods as a result of which low positivity is often obtained even in well equipped centres. The rapid biopsy urease test for the diagnosis of C pylori infection, in which the biopsy is directly cultured in a solid medium containing urea, is a very simple test. A change in colour indicates the growth of the organism. This test is 100% specific and 98% sensitive. We performed this test in 100 patients; 93 of gastritis, 6 of DU and 1 of GU during a three month period. 87 of 93 cases of gastritis (90%) and all 6 cases of DU (100%) were positive. The single case of gastric ulcer was negative. Treatment of C pylori positive cases showed that they responded poorly to 4 weeks therapy with tinidazole; 33% were cured after 2 weeks of 1.5 g amoxycillin daily, but all responded when the therapy was continued for 4 weeks.
