The response of nematodes in vivo and in vitro to some anthelmintics

Dietary feeding of drugs for 5 days to mice infected with Nematospiroides dubius and Hymenolepis nana detected all modern anthelmintics examined except stilbazium. A simple test using eggs of Nematodirus spathiger and adult Nippostrongylus brasillensis to detect anthelmintics in vitro is reported.
