Porocephalida is an order of tongue worms. [1] Some species in this order, such as Armillifer grandis , have been found in vipers from bushmeat markets. [2] [3] They are have a vermiform, ringed body, and inhabit respiratory tracts of vertebrates. [4]
Some species are a health risk to humans, particularly through the consumption of infected hosts, such as vipers sold to humans from bushmeat markets in Central and West Africa. [5] Ingestion may lead to porocephaliasis when nymphs invade internal organs. Severe infections can cause abdominal distress and sometimes blindness. [6]
There are four families recognised in the order Porocephalida: [1]
