Abstract
Specimens of parasitic helminths were obtained from 9 amphibians (6 species) and 44 reptiles (19 species) died in Osaka Municipal Tennoji Zoo between 1994 to 1996. Four species amphibians and 14 species reptiles in the present study were foreign species in Japan. The species of helminths were as follows: 5 orders, 11 families of nematodes (24 species) Abbreviata bufonis, Alaeuris geochelone, Batrachostrongylus longispiculus, Cosmocercoides pulcher, Falcaustra pahangi, Hexametra sp., Macdonaldius oschei, Mehdiella microstoma, Meteterakis sp., Ophidascaris niuginiensis, Orneriness sp., Ozolaimus cirratus, O. megathphlon, Parapharyngodon maplestoni, Physocephalus sp., Polydelphis sp., Rhabdias horiguchii, R. incerta, Serpinema trispinosus, Spinicauda regiensis, Tachygonetria conica, T. dentata, T. microlaimus and Tanqua tiara; 1 order, 1 family of trematode (1 species) Telorchis clemmydis; 3 orders, 3 families of cestodes (4 species) Acanthotaenia shipley, Duthiersia expansa, Oochoristica agamae and Spirometra erinaceieuropaei and 1 order, 1 family of pentastomid (1 species) Raillietiella affinis. The locations of each species in animals were also presented. Today, these amphibians and reptiles are kept as exotic pets in Japan. Most of the helminths obtained from exotic hosts in the present study are not distributed in Japan, but can be introduced with their hosts into this region as non-native parasites.
