Most infection is acquired in childhood after the age of 2, probably transmitted by the oral-oral or faecal-oral route and has reached a prevalence of approximately 20% by the age of 25, subsequently rising by 1% a year.
Once eradicated, re-infection is unusual and occurs at 1% per annum. DETECTION Invasive techniques for detecting H. pylori require endoscopic biopsy of gastric mucosa and allow detection by urease, culture or histology. Non-invasive techniques detect serum antibodies or exhaled radio-labelled carbon split from urea by H. pylori urease, and probably represent the best technique for detecting H. pylori when sensitivity, specificity and cost are considered (Table 1).
