pertonic effects exerted by the flotation solu tion. The methods most frequently used to recover parasite eggs and oocysts are flotation techniques that rely on the differences in the specific gravity (SG) of the egg(s), fecal debris, and flotation solution. The SG of most parasite eggs is between 1.05 and 1.23.1 For parasite eggs to float, the SG of
