Description of the patient cohort and isolation of study samples
A total of 109 H. pylori samples were isolated from an initial number of 359 biopsies included in this study (yielding an apparent infection rate of 30.4%), of which 60 (55%) were derived from male patients and 49 (45%) isolates came from female patients (sex ratio F/M: 0.82). The average patients’ age at the time of endoscopy was 39 ±17 years. From the 109 patients with established H. pylori infection, 81 patients had presented with a non-ulcer dyspepsia, nineteen patients with a peptic ulcer dyspepsia and nine patients with GC (Signet Ring Cell
