Isolation of campylobacter-like bacteria from gastric epithelium.

Nineteen gastric biopsies were examined for campylobacter-like gram-negative bacteria. Such strains could be isolated in six out of the 19 biopsies, as confirmed histologically. The bacteria are sensitive to tetracycline, clindamycin, erythromycin, cefalothin, penicillin G and ampicillin and resistant to nalidixic acid and metronidazole. They grow in a 6% O2, 10% CO2 atmosphere at 37 degrees C.
