Helicobacter pylori cagA status, vacA genotypes and ulcer disease.

European journal of gastroenterology & hepatology - 1 May 1998

Stephens J C, Stewart J A, Folwell A M, Rathbone B J

Abstract excerpt

OBJECTIVE: Helicobacter pylori is the causative organism of peptic ulcer disease and has two putative virulence determinants: the cagA gene which encodes a protein of unknown function in 60% of strains, and the vacA gene, which is present in all strains, although active cytotoxin is produced in o...
