Genus of the nematode family Filariidae.

General Information

The up to 6.5 cm long females of this genus (e.g., P. bovicola) – males reach 3.5 cm – introduce nodules in the subdermal skin of cattle in South Asia, Africa, and in some regions of Europe. Vectors are Musca spp. which transit the L 3 that reaches maturity in about 6–7 months (Fig. 1). The microfilariae are found in wounds of the skin due to the presence of adults and then become licked by the flies. The symptoms of the disease are 10–15 cm-sized lesions in the skin and exudations of open wounds (often called summer wounds).
