Schistosoma malayensis

Schistosoma malayensis is a schistosome parasite. It was first described in 1988 in Peninsular Malaysia and appears to be a zoonotic infection. The species is named after the country of Malaysia. The natural vertebrate host is van Müller's rat (Rattus muelleri). The intermediate hosts are aquatic snails, Robertsiella kaporenisis. Aside from Robertsiella kaporenisis, two other Robertsiella species are reported intermediate hosts.

Among humans exposed to this parasite the lifetime incidence appears to be 5–10%. The symptoms are unclear, because the symptoms have never been reported. The disease has been little studied and it is currently considered to be a relatively minor public health problem.
