Physaloptera spp. as human parasites

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]
