Comments P.461 left column 2nd paragraph: "As the environmentally stable form of the life cycle, cysts have a metabolic rate only 10 to 20% of that found in trophozoites (primary source). The respiration of both cysts and trophozoites is stimulated by ethanol, while trophozoites are stimulated only by glucose." Primary source abstract: "Cysts and trophozoites of the parasitic protozoon Giardia muris both showed respiratory activity but respiration in cysts was only 10 to 20% that of trophozoites."
