A Review of Rat Lungworm Infection and Recent Data on Its Definitive Hosts in Hawai‘i
Rat lungworm (Angiostrongylus cantonensis) is a zoonotic nematode that causes rat lungworm disease (angiostrongyliasis), a potentially debilitating form of meningitis, in humans worldwide. The definitive hosts for rat lungworm are members of the genus Rattus, with gastropods as intermediate hosts. T...
