Overview
Capillaria spp. are similar to other members of the Trichuroidea superfamily such as Trichuris but with slight differences in morphology of the anterior and posterior ends. Although they are found in domestic mammals these species are of greatest importance in birds. The predilection sites vary between species and are not restricted to the gastrointestinal system. Important species include; C. annulata, C. anatis and C. contorta.
Identification
Capillaria are extremely thin, filamentous worms measuring 15-25mm long in males and 35-80mm long in females. Males have a single spicule and many have a primitive bursa like structure
- Capillaria aerophila in respiratory disease of cats and dogs
- In nasal passages, sinuses, trachea and bronchi of cats and dogs
- Some dogs cough but often no symptoms
- Mild catharral inflammation
- In heavy infestation may cause obstruction of the lumen of airways and may develop into secondary bronchopneumonia
