Survey of parasitological examinations performed by the Department of Parasitology, Kawasaki Medical School, 3. results: 1996 to 2003 *
In Parts 1 and 2 of this survey, the authors previously reported on parasitological examinations of 435 and 725 materials, respectively, requested from within and outside of Kawasaki Medical School between 1976 and 1995 and the results of their studies（Hatsushika et al., 1988, 1996）. The present paper describes an additional 169 materials dealt with in our laboratory between 1996 and 2003. Sixty-two（36.7％）of the total cases demonstrated infection with endoparasites or ectoparasites. The causative parasites found were as follows:（Protozoa）Entamoeba histolytica（three cases）, E. coli（one case）;（Nematoda）AnisakisⅠ-type larva（six cases）, three cases each of Ascaris lumbricoides, Trichuris trichiura, two cases each of Enterobius vermicularis and Thelazia callipaeda, one case each of Necator americanus, Strongyloides stercoralis, Loa loa and nematoda sp. ;（Trematoda）one case each of Heterophyidae and Echinostoma hortense; （Cestoda）Diphyllobothriidae（seven cases）, Diphyllobothrium latum（three cases）, one case each of D. orcini, Taeniarhynchus saginatus and Cysticercus cellulosae;（Arthropoda）Haemophysalis longicornis（seven cases）, Ixodes nipponensis（four cases）, I. ovatus（three cases）, one case each of Ornithonyssus bacoti, Demodex folliculorum, Sclerodermus nipponicus, Blattidae, Blattella nipponica, Parasarcophaga similis, Dermatobia hominis, Pediculus humanus corporis and Caligus sp. in the order of frequency of appearance. Characteristic of this survey was the fact that cases in which the causative parasites were discovered and removed by endoscopy comprised about a quarter of all the positive cases. Furthermore, endoscopy has been shown to be useful in the diagnosis of intestinal parasites. （Accepted on August 3，2005）
