Nippostrongylus brasiliensis

Nippostrongylus brasiliensis is a gastrointestinal roundworm or nematode that infects rodents, primarily rats. This worm is a widely studied parasite due to its simple life-cycle and its ability to be used in animal models. It has a life-cycle similar to the human hookworms Necator americanus and Ancylostoma duodenale which includes five molting stages to become sexually mature.
