FRESHWATER-FISHES OF THAILAND AS EXPERIMENTAL INTERMEDIATE HOSTS FOR CAPILLARIA-PHILIPPINENSIS

Bhaibulaya M., Indra-Ngarm S. and Ananthapruti M. 1979. Freshwater fishes of Thailand as experimental intermediate hosts for Capillaria philippinensis. The International Journal for Parasitology 9: 105-108. Nine species of freshwater fishes from Thailand have been exposed to infection with embryonated eggs of Capillaria philippinensis. The eggs were fed to fishes with food or through a polyethylene tube. After 10-30 days larvae capable of establishing intestinal capillariasis in Mongolian gerbils were recovered from six fish species: Cyprinus carpio, Puntius gonionotus, Aplocheilus panchax, Gambusia holbrookii, Rasbora borapelensis, and Trichopsis vittatus. Larvae were not recovered from Tilapia nilotica, Osteochilus hasseltii and Trichogaster trichopterus. Five human cases of intestinal capillariasis have been reported from widely scattered areas of Thailand and the natural intermediate and definitive hosts remain to be determined. © 1979.
