===''C. annulata''===

This species affects many species of wild birds as well as domesticated poultry and ducks. The predeliction site for this worm is the oesophagus of the bird where it will bury the anterior end into the mucosa causing inflammation. High levels can resulted in marked thickening of the oesophageal wall and can be fatal.

This species affects many species of wild birds as well as domesticated poultry and ducks. The earthworm is the intermediate host for this species, making it difficult to control. Young birds are more susceptible to the disease will immune adults may be carriers. The predeliction site for this worm is the oesophagus of the bird where it will bury the anterior end into the mucosa causing inflammation. High levels can resulted in marked thickening of the oesophageal wall and can be fatal. The presence of these worms in low numbers may be a cause of ill thrift in production birds, though in high number emaciation can be seen. Clinical signs may appear very rapidly with heavy burdens, before the presence of eggs in the faeces, and so diagnosis is usually made on necropsy examination of the oesophagus and crop.
