Numerous parasitological and ecological studies confirm that many parasite species utilize multiple sequential host species to successfully complete complex life cycles and facilitate transmission.
The retrieved literature thoroughly supports the premise that many parasites rely on complex life cycles involving multiple host species (such as intermediate, paratenic, and definitive hosts) to complete their development and ensure transmission. Papers [2], [4], [6], [8], and [11] all explicitly discuss this phenomenon without any contradictory evidence.
