Effect of Oxidizing Disinfectants (Chlorine, Monochloramine, and Ozone) on <i>Helicobacter pylori</i>

Abstract

The susceptibility of Helicobacter pylori to disinfectants was compared to that of Escherichia coli. H. pylori is more resistant than E. coli to chlorine and ozone but not monochloramine. H. pylori may be able to tolerate disinfectants in distribution systems and, therefore, may be transmitted by a waterborne route.
