The lung hairworm ( Capillaria aerophila , Syn. : Eucoleus aerophilus ) is in the lungs of mammals parasitierender hairworm . It is common in foxes and hedgehogs, and occasionally it also occurs in dogs and cats. Other wild canids such as raccoon dogs , martens , wolves and lynxes are also attacked, and even human infections have been described.
Adult lung hairworms are up to 25 mm long and live in the airways. The eggs produced by the female worms have two pole pods and thus resemble those of whipworms ( Trichuris ssp.). However, they have a colorless to greenish, granular skin. The eggs are deposited in the airways and pass through coughing up and swallowing into the gastrointestinal tract and finally into the environment via the feces. They can be detected by means of a flotation method or examination of the lung lavage fluid .
The infection is done by recording with eggs contaminated feed or water. The larvae hatch in the intestine and enter the lungs via the bloodstream . The prepatency is about 40 days. The lung hairworm rarely causes symptoms; bronchitis with coughing only occurs when the infection is more severe - usually as a result of accompanying bacterial infections .
