Heterakis is a genus of parasitic nematodes.Members of the genus are minute roundworms (), hardly 1 cm long, infecting different species of gallinaceous birds, including chickens, turkeys, ducks, geese, grouse, guineafowl, partridges, pheasants, and quail.
Both species of roundworm occur worldwide and roundworm infestation is a very common endoparasitosis. The adult roundworms, up to 10 cm long, live in the small intestine. The female worms produce a large number of eggs, which are released into the environment with the feces. The infective larvae develop in the eggs after about four weeks.
Once the cat ingests the infected eggs, they hatch and the larvae mature as adults in the large intestine, where they feed on the blood from the intestinal wall. T. campanula lays eggs that are passed in the feces of the infected cat, remaining alive in soil for years. The infection can be found by examining the feces of the infected cat.

These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms can lead to the syndrome of elephantiasis. Loiasis a subcutaneous filariasis is caused by Loa loa (the eye worm). Mansonella streptocerca, and Onchocerca volvulus. These worms occupy the layer just under the skin. O. volvulus causes river blindness.

Most of Filarioidea parasitise wild species, birds in particular, but some, especially in the family Onchocercidae, attack mammals, including humans and some domestic animals. Conditions that result from parasitism by Onchocercidae include some of the most troublesome diseases of the warmer regions, including river blindness and elephantiasis .
