Inactivation of Helicobacter pylori by chlorination
Article Abstract:
Research was conducted to examine the resistance of Helicobacter pylori strains to chlorination. A bacteriological loop was utilized to aseptically remove organisms while triplicate experiments were conducted for each isolate at each pH level. Moreover, the occurrence of particulate material in the cultures was studied to examine the difference in CT99 values between H. pylori and Escherichia coli. Results indicated that H. pylori was sensitive to chlorine.

Nine-year study of the occurrence of culturable viruses in source water for two drinking water treatment plants and the influent and effluent of a wastewater treatment plant in Milwaukee, Wisconsin (August 1194 through July 2003)
Article Abstract:
The influent and effluent of a local wastewater treatment plant (WWTP) were tested monthly by a modified U.S. Environmental Protection Agency Information Collection Rule (ICR) organic flocculation cell culture procedure for the detection of culturable viruses. Eighteen of 204 samples of source waters for the two drinking water treatment plants were positive for virus and exclusively positive for reoviruses at relatively low titers.

Chlorine-susceptible and chlorin-resistant type 021N bacteria occurring in bulking activated sludges
Article Abstract:
The failure of sludge chlorination to prevent filamentous bulking in wastewater treatment plants may occur because the microbial community in the sludge is resistant to chlorine. Researchers describe two filamentous bacteria that cause bulking in wastewater, one of which is sensitive to chlorine and one of which is resistant.
