Angiostrongylus Cantonensis Top Open Access Journals

Angiostrongylus cantonensis may be a parasitic nematode (roundworm) that causes Angiostrongyliasis, the foremost common explanation for eosinophilia meningitis in Southeast Asia and therefore the Pacific Basin. The nematode commonly resides within the pulmonary arteries of rats, giving it the common name rat lungworm. Adult worms of A. cantonensis sleep in the pulmonary arteries and ventricle of the traditional host image. The females lay eggs that hatch within the terminal branches of the pulmonary arteries, yielding first-stage larvae. The first-stage larvae migrate to the pharynx, are swallowed, and passed within the feces. They penetrate or are ingested by a gastropod host image. After two molts, third-stage larvae are produced image which are infective to mammalian hosts. When the infected gastropod is ingested by the host, the third-stage larvae migrate to the brain where they become young adults image . The young adults return to the venous system then the pulmonary arteries where they become sexually mature. Of note, various animals act as paratenic (transport) hosts: after ingesting the infected snails, they carry the third-stage larvae which may resume their development when the paratenic host is ingested by a host.
