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 parasitize primates, including humans. [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]
