<unk>  is a parasitic nematode which causes<unk> unk> sis in rodents and numerous other mammal species, including humans. The life cycle of C.<unk>  may be completed in a single host species. However, the eggs, which are laid in the liver, must mature outside of the host body (in the environment) prior to infecting a new host. So the death of the host in which the adults reach sexual maturity, either by being eaten or dying and decomposing, is necessary for completion of the life cycle.
