Fig. 4From: Phenotypic screening of the ‘Kurz-box’ of chemicals identifies two compounds (BLK127 and HBK4) with anthelmintic activity in vitro against parasitic larval stages of Haemonchus contortusEffect of the compound BLK127 on the development of exsheathed third-stage larvae (xL3) to the fourth-stage (L4) after 7 days. a Percentage of L4, xL3 with/without evisceration (Evi) phenotype with reference to a negative (untreated) control (NC) LB* + 0.5% DMSO. b Dose–response curve for inhibition of L4 development. L4 development was assessed by light microscopy. **** denotes significance: P < 0.0001 compared to the NCBack to article page
