The Parasite Fasciola hepatica, the common liver fluke, is the most likely cause of liver fluke disease in domestic ruminants in the United States. The fluke life cycle requires a snail intermediate host to complete transmission to a new ruminant host. The parasite is most often found in Florida, along the Gulf Coast, in the Pacific Northwest, in portions of the Rocky Mountains, and Hawaii. Oth...
Parasites can impart heavy fitness costs on their hosts. Thus, understanding the spatial and temporal consistency in parasite pressure can elucidate the likeliness of parasites' role as agents of directional selection, as well as revealing variable environmental factors associated with infection risk. We examined spatiotemporal variation in digenetic trematode infection in 18 populations of an ...
Paragonimiasis is an infection caused by lung flukes of the genus Paragonimus. In Asia, P. westermani infections are relatively common because of dietary practices. However, in North America, cases of paragonimiasis, which are caused by P. kellicotti flukes, are rare. Only 7 autochthonous cases of paragonimiasis were reported during 1968-2008. In 2009, we reported 3 new case-patients with parag...
