Fifty-two patients with gastric disorders referred to the same physician over the course of one year were endoscoped, biopsied and given a14C breath test to identifyHelicobacter pylori. Sensitivity, specificity and accuracy of the14C breath test were found to be 83%, 89% and 87%, respectively, when taking biopsy results as the `gold standard'. These figures rose to 85%, 93% and 89%, respectively, when the first five cases were not included, representing a ‘learning curve’ associated with the development of cut-off levels for the breath test. In five cases, persons were biopsied and given a breath test at least one month later, making 10 comparisons possible. Biopsy and breath test corresponded in nine of 10 comparisons (90%). In two of four false negatives (14C breath test negative but biopsy positive) only scant numbers of helicobacter organisms were found. In one of three false positives (14C breath test positive but biopsy negative) acute inflammation of the duodenal biopsied material was detected. Also, double eradication therapy (omeprazole 20 mg bid and amoxicillin trihydrate 1000 mg bid), administered in all three false positive cases, was followed by14C breath testing six weeks later, which indicated normal scores or absence of the organism.

Helicobacter pylori is a microaerophilic, gram-negative bacterium found in the upper gastrointestinal tract of humans. There is strong evidence that H. pylori is important in the etiology of gastritis; the bacterium may also be a major predisposing cause of peptic ulceration. On the gastric mucosa, the organism exists as a spiral form with one to seven sheathed flagella at one (usually) or both poles. Short spirals were seen in the first successful culture of the organism in 1983. In 1984, Marshall and Warren reported a coccoid form in older cultures. Since that time, other workers have observed rod and coccal forms in vitro; coccoid forms predominate in cultures 3-7 days old. We sought to examine the growth cycle of H. pylori in prolonged culture and the mode of coccoid body formation.
