Overview

Capillaria - Courtesy of the Laboratory of Parasitology, University of Pennsylvania School of Veterinary Medicine

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.

  • Similar to Trichuris, but the difference between anterior and posterior ends of the body is not so pronounced
  • Some species have direct life-cycles, others use intermediate or transport hosts
  • Species have different predilection sites
  • Of greatest importance in birds, although species do occur in the urinary bladder and liver of cats and dogs

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 a primitive bursa like structure
