The Effect of Macrocyclic Lactones-Ivermectin Exposure on Egg Hatching and Larval Development of .

To date, the ivermectin resistance in nematode parasites has been reported and many studies are carried out to determine the causes of this problem. A free-living is used as a model system for this study to investigate the response of to ivermectin exposure by using larval development assay. Worms were exposed to ivermectin at concentration from 1 ng/mL to 10 ng/mL and dimethyl sulphoxide (DMSO) as a control.
