Assessment of the effectiveness of low-pressure UV light for inactivation of Helicobacter pylori.
Three strains of Helicobacter pylori were exposed to UV light from a low-pressure source to determine log inactivation versus applied fluence. Results indicate that H. pylori is readily inactivated at UV fluences typically used in water treatment regimens. Greater than 4-log(10) inactivation was demonstrated on all three strains at fluences of less than 8 mJ cm(-2).
