Pathogenesis of Paragonimus westermani

Pathogenesis of Paragonimus species infection. Paragonimus species is transmitted to humans after eating raw or undercooked crabs, crayfish or shellfish and other infected crustaceans (Figure 1). Human infections with the parasite can be asymptomatic or symptomatic depending on the magnitude of Paragonimus invasion. Paragonimiasis is endemic in places where crayfish, crabs and shellfish are ingested as a delicacy either raw or in juicy forms Most published literature deals with pulmonary paragonimiasis due to P. westermani although in some geographic areas other Paragonimus species cause similar or distinct clinical manifestations in human infections. Cross-reactivity between species does occur but at varying levels for different species Several species of Paragonimus cause most infections; the most important is P. westermani, which occurs primarily in Asia including China, the Philippines, Japan, Vietnam, South Korea, Taiwan, and Thailand. P. africanus causes infection in Africa, and P. mexicanus in Central and South America Of the 10 or more Paragonimus species that are human pathogens, only 8 cause significant infections in humans. The first case described in humans was at autopsy in Taiwan in 1879, when adult flukes..

Hemoptysis. Paragonimiasis is a cause of parasitic hemoptysis worldwide. Paragonimiasis is infrequently encountered in North America and is usually not considered in the differential diagnosis of hemoptysis unless specific risk factors are known.

For Paragonimus westermani, ingestion of raw meat from mammalian paratenic hosts provides an additional route of infection (Blair 2014). Human Paragonimus infection can be efficiently treated with a short course of praziquantel, but diagnosis is challenging, because infected people are often misdiagnosed and treated for pneumonia, tuberculosis. Whereas in Europe helminth parasites of the central nervous system are larval tapeworms-either Echinococcus or Cysticercus-in Japan the parasites found are the adults or eggs of flukes, viz., Schistosoma japonicum and Paragonimus westermani. The author describes in detail the results of his examination of the brain of a Japanese policeman, aged 43, in which were found great numbers of cysts due.. This report provides advances in molecular understanding of Paragonimus and underpins future studies into the biology, evolution and pathogenesis of Paragonimus and related food-borne flukes.
