Physaloptera is a genus of parasitic nematodes in the family Physalopteridae. Species include:
Undescribed or unidentified species have been found on the hispid cotton rat (Sigmodon hispidus) in the southern United States,[4] the marsh rice rat (Oryzomys palustris) in Florida,[8] and Leontopithecus rosalia, Physalaemus soaresi, Cacajao calvus, and Lagothrix lagotricha in Brazil.[2]
Most species utilize insects such as crickets, cockroaches, and beetles as intermediate hosts.[9] Several species of Physaloptera can be parasites of primates and man.[10][11] This rare disease is known as spiruridiasis. Human infection is considered to be ancient; eggs of Physaloptera sp. were found in a grave of the Bronze Age in Iran.[9]
