Gongylonema ingluvicola
''Gongylonema ingluvicola'' is a species in the genus ''Gongylonema''. It is one of the spirurid nematodes that infect a vast array of animals throughout the world. Infections have been noted in both humans and in animals ranging from cows to birds. As of recent, there have been 50+ human cases reported in countries such as New Zealand, Australia, Middle East, China, and United States.
G. ingluvicola, like other tissue-dwelling species, require an insect intermediate host to ingest eggs. Infections result from the ingestion of intermediate hosts containing L3 stage nematodes. Upon ingestion of the insect by an appropriate host, the larvae are released and can migrate to the esophagus or buccal cavity. Humans are an accidental host who occasionally get infected by ingesting infected poultry or insects. Infected humans have described a moving sensation in the buccal cavity which includes, but is not limited to, lips, gums, tongue, and palate. Symptoms include local irritation, pharyngitis and stomatitis and bloody oozing patches in the mouth.〔〔
G. ingluvicola is commonly recognized in the esophageal epithelium of birds such as chickens, turkeys and pigeons. This worm stage burrows through the epithelium, leaving trails of eggs which find their way to the lumen, get swallowed, and eventually pass in feces. A related species, ''G. pulchrum'', infects a variety of mammals but rarely humans.〔(【引用サイトリンク】url=http://compepid.tuskegee.edu/syllabi/pathobiology/pathology/parasitology/chapter13.html )〕
