神经冲动

Content: Avermectins belong to a group of compounds called macrocyclic lactones, which are natural products produced by the microorgamanism streptomyces avermitilis. In recent years the AVMs are used as a potent antiparasitic animal health drug in the treatment of parasitic infections for food producing animals.
