<unk>  is a nematode parasite found in the respiratory tract of foxes, dogs, and various other carnivorous mammals. A few cases of human infestation have also been reported. Though it is sometimes called a "lungworm", this term usually refers to other species of nematodes. Infestation by C.<unk>  is referred to as "pulmonary<unk> sis" (occasionally spelled "capillariosis), "bronchial<unk> sis," or (rarely) "thominxosis." This parasite has a direct life cycle, meaning that the life cycle can be completed in a single host. C.<unk>  usually causes only minor clinical symptoms, such as irritation of the respiratory tract and coughing. However, secondary bacterial infections of the respiratory tract, including pneumonia, may develop in heavy infestations. Treatment with anthelmintics, such as levamisole or fenbendazole, is usually sufficient to cure C.<unk>  infestations.
