Many newly recognized waterborne pathogens, such as Microsporidia and Mycobacteriumavium, have been shown to be resistant to conventional disinfection practices. In this study, Encephalitozoon intestinali and Mycobacterium fortuitum were exposed separately to medium pressure ultraviolet (UV) light using a collimated beam apparatus supplied by Calgon Carbon Corporation. Organisms were seeded into phosphate buffered saline and a series of UV doses were chosen for each organism to establish a dose response curve. Microsporidia inactivation was determined using cell culture methodology, while Mycobacterium was evaluated using standard culture techniques. Includes 13 references, figures.
