title: Efficacy of ivermectin against Parastrongylus malaysiensis infection in rats.
abstract: The efficacy of ivermectin on experimental infections of P. malaysiensis in rats was determined. Ivermectin was 99.4% and 97.9% effective at a dosage of 400 meg and 800 meg respectively at seven days post-infection. The same two dosages of ivermectin when given at 14 days post infection had an efficacy of 100%. However, as an adulticide it had only 40.7% efficacy. Ivermectin may therefore be useful for the treatment of parastrongyliasis due to the larval stages of the worm which can cause significant pathology in man and animals.
