From Wikipedia – Platydemus manokwari, also known as the New Guinea flatworm, is a species of large predatory land flatworm.
Platydemus manokwari is a paratenic host for the nematode Angiostrongylus cantonensis, also known as the rat lungworm. This nematode parasitizes Platydemus manokwari as well as the Giant African land snail, and both of these organisms are transmission vectors of the parasite. A. cantonensis parasitizes humans as well and causes angiostrongyliasis. Platydemus manokwari acts as a transmission vector of the parasite to humans and affects the epidemiology of angiostrongyliasis. In an outbreak of angiostrongyliasis in the Okinawa Prefecture, populations of Angiostrongylasis cantonensis intermediates were examined in order to find the most frequently infected intermediates. Platydemus manokwari was found to be one of the prevailing infected hosts, with an infection rate of 14.1%. It is likely that Platydemus manokwari is a vector because it deposits A. cantonensis larvae on the underside of cabbage leaves, where it commonly lives.
