Emodepside is an anthelmintic with a distinct mode of action which may involve a latrophilin receptor (Bernt et al. 1998). Here we report preliminary studies using the nematode Caenorhabditis elegans for behaviour and Ascaris suum for physiology, with the aim of identifying the genetic basis of emodepside action.

The effect of emodepside on a synchronized population of C. elegans (N2 Bristol strain) was determined. Approximately 100 eggs were placed on agar plates containing E. coli (OP50) and either emodepside (100 pM
