Biomphalaria glabrata infected with Angiostrongylus cantonensis: Proteomic changes in the snail host.

Angiostrongylus cantonensis is the main cause of human eosinophilic meningitis. Humans are accidental hosts, becoming infected due to ingestion of raw intermediate (snails and slugs) or paratenic hosts. Once ingested, the larvae migrate towards the brain where they die, causing the disease.
