- Abstract: Combined technic of formalin-ether sedimentation and zinc sulfate flotation was carried out to compare the detection rate of Paragonimus eggs in feces between formalin-ether sedimentation technic and zinc sulfate centrifugal flotation, using the feces of cat infected with Paragonimus westermani for former and intestinal contents of rabbit infected with Metagonimus yokogawai for latter. And following results were obtained. Zinc sulfate method was highly excellent in detection of Paragonimus eggs in feces, on the contrary, formalin-ether technic was very poor, and the other hand, formalin-ether technic was highly excellent in detection of Metagonimus eggs, on the contrary, zinc sulfate method was extremely poor. The time which was needed in carrying out the combined technic was shorter than the cumulative time of each of the formalin-ether technic and zinc sulfate method was. Author emphasizes that the combined technic may be used in general parasitic examination of feces, so that excellent results would be obtained in detection of all kinds of helminthic ova and protozoa.
