Abstract
|
|
|
Experiments had been made to evaluate more efficient method in stool examination for various helminth ova. Authors examined 2,016 nationwidely colleted stool specimens by´the two ´ methods, cellophane thick smear method and brine floatation method.
The results were as follows;
1. Of 2,019 specimens examined by cellophane thick smear method, the positive rates of following helminth ova were; Ascaris lumbricoides (fertilized) 27.3%, Ascaris lumbricoides (unfertilized) 13.6%. Tr ichuris trichiura 39.0%, Hookworm 0.1%, Enterobius vermrcularis 0.05%, :lymerolepis Tana 0.4%, Taenia spp, 1.3 0, Clonorchis sinensis 1.1%, and ltletagonimus yokogawai 5.70.
And, A. lumbricoides (fertilized) 27.0%, A. lumbricoides (unfertilized) 3.390, T, trichiura 33.1%, Hookworm 2.0%, Trichostrongylus orientalis 0.6%, E. vermrcularis 0.2%, H. nar.a 0.8%. and M. yokogawai 0.05% by brine floatation method.
2. The causes of inferior positive rates in some helminth ova by cellophane thick smear method were shortly discussed and suggest some opinions in improvement of detection ability.
3. The positive rates of following helminth ova were superior in cellophane thick smear ma-thod to those of brine floatation method: A. lumbricoides (fertilized), Taenia spp. , C. simcns:s and nf. yokogawai.
And, the positive rates of following helminth ova were superior in brine floatation method: Hook-worm, T. orientalis, H. rana and E. vermrcularis.
4. Cellophane thick smear method has been known to be one of the most effective methods in mass stool examination. -But, this method is not so effective in detection of certain species of helminth ova.
Therefore, employment, of brine floatation method added to cellophane thick smear method is desir--able for the better result of-mass stool examination.
