Acanthocephalus is a genus of parasitic worms. One of the species in this genus is Acanthocephalus anguillae (Mueller, 1780),[citation needed] a fish parasite. Acanthocephalans are also found in humans and primates, causing a common zoonotic infection called "human acanthocephaliasis". While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis is the diet of infected raw fish and insects (Lotfy, 2020).[citation needed] Because they are lacking circulatory, respiratory, and digestive systems, Acanthocephalus are exceptionally well-adapted to a symbiotrophic existence (Margulis & Chapman, 2009).[citation needed]
Life Cycle
There are 5 steps in which Acanthocephala cycles through life; (1)Their eggs shed in feces. (2)These eggs are then ingested by their host. (3)The definitive host then gets infected due to ingesting the eggs from the first host. (4)The definitive host is either rats or raccoons and therefore, in this step the Acanthocephala matures in the small intestine. (5)Lastly, the Acanthocephala matures and also produces eggs inside the definitive host (Centers for Disease Control and Prevention, 2019).[citation needed]
