Abstract

To evaluate the Kato's cellophane thick smear techcique in detection ability of various helminth ova, authors examined 1,843 nationwidely collected stool specimens by the two methods, formalin-ether technique and cellophane thick smear technique. And the results were analyzed. The positive rates of following helminth ova were superior in cellophane thick smear technique to those of formalin-ether technique: Ascaris lumbricoides(62.3% : 51.1%), Taenia species (1.5% : 0.9%). The difference in A. lumbricoides ova detection is highly significant one. The overall positive rate for helminths ova was also higher in Kato's method (92.3% : 90.0%). The positive fates of following helminth ova were infrior in cellophane thick smear technique to those of formalin-ether technique: Hookworm (5.8% : 14.6%), Trichostrongylus orientalis(3.2% : 17.8%), Clonorchis sinensis(8.3% : 11.0%), Metagonimus yokogawai (0.6% : 1.7%) and Hymenolepis nana(0.05% : 0.3%). The positive rate for the ova of Trichocephalus trichiurus by the two methods was incidentally same, 74.1%. The causes of inferior positive rates in some helminth ova by cellophane thick smear technique were shortly discussed and suggests some opinions in improvement of detection ability.
