Cytotoxin production by Campylobacter pylori strains isolated from patients with peptic ulcers and from patients with chronic gastritis only

Abstract

A total of 66.6% of Campylobacter pylori strains isolated from patients with peptic ulcers produced a cytotoxin active against mammalian cells in vitro, versus 30.1% of strains isolated from patients with chronic gastritis of various degrees of severity only. This difference was statistically significant and suggests that the toxic substance could be involved in the development of peptic ulcers.
