The evaluation of anthelmintic resistance: how good are we ?

Communication oraleInternational audienceThe evaluation of anthelmintic resistance is still based on faecal egg count reduction test (FECRT) since molecular mode of action remains unclear or unknown for most anthelmintics. The evaluation based on FECRT is greatly depending on the level of infection, the intensity of resistance, the number o and the procedure of sampling. The mode of calculation of efficacy of anthelmintics can be based on several statisticl procedures that may affect the evaluation of efficacy. There is a real need for establishing a guide for evaluating in practice resistance of nematodes to anthelmintics
