Self-induced Increase of Gut Motility and the Control of Parasitic Infections in Wild Chimpanzees
When physiological adaptation is insufficient, hosts have developed behavioral responses to avoid or limit contact with parasites. One such behavior, leaf-swallowing, occurs widely among the African great apes. This behavior involves the slow and deliberate swallowing without chewing of whole bristly leaves.
