The Syngamidae are a family of nematodes which commonly parasitize mammals, birds, and rarely humans.〔Anderson RC, Chabaud AG, Willmott S. CIH keys to the nematode parasites of vertebrates, no 7. Keys to genera of superfamily Strongyloidea. Commonwealth Agricultural Bureaux, England, 1980.〕 They are classified in the Strongyloidae superfamily and Strongylata order.〔Eamsobhana P, Mongkolporn T, Punthuprapasa P, Yoolek A (2006). "Mammomonogamus roundworm (Nematoda: Syngamidae) recovered from the duodenum of a Thai patient: a first and unusual case originating in Thailand". ''Trans R Soc Trop Med Hyg'' 100: 387–91.〕 Notable species within the Syngamidae family include ''Syngamus trachea'', commonly known as the gapeworm, which infests birds, and ''Mammomonogamus laryngeus'', which is a parasite of ungulates, cats, and orangutans, and which can accidentally infect humans.〔 Parasitic infection occurs when the host ingests the parasite via contaminated food, water, or intermediate hosts like earthworms, snails, and arthropods. Worms usually migrate and inhabit the respiratory tract of hosts, where the male and female worms join in permanent copulation.〔Severo LC, Conci LMA, Camargo JJP, Andre-Alves MR, Palombini BC. Syngamosis: two new Brazilian cases and evidence of possible pulmonary cycle. ''Trans R Soc Trop Med Hyg.'' 1988;82: 467–8.〕 Syngamidae nematodes are globally distributed and are important in veterinary parasitology.〔Gutierrez, Yezid.
