Zusammenfassung:A method of controlling protozoa trophozoites and cysts is disclosed. The method comprises the addition of guanidine or biguanidine salts to aqueous systems harboring protozoa trophozoites and cysts. Addition of such materials to aqueous systems was found to be effective at controlling both the protozoa trophozoites and cysts. By effectively controlling both the protozoa trophozoites and cysts, organism such as Legionella cells harbored in both the trophozoites and cysts are in turn controlled.
