Figure 4From: A controlled study on gastrointestinal nematodes from two Swedish cattle farms showing field evidence of ivermectin resistanceDose-response curves, larval migration inhibition test. Dose-response curves of the data obtained in LMIT with the three different isolates of L3 larvae, showing no significant difference between groups. Calves in group A were infected with equal mixtures of laboratory-maintained C. oncophora and O. ostertagi from TiHo, and those in groups B and C with cattle nematodes from two different farms in Uppland, Sweden, showing phenotypic clinical IVM resistance in previous field trials.Back to article page
