Distortion of the gizzard in Cyprus pigeons (Columba livia) associated with Hadjelia truncata infestation.

Hadjelia truncata is well recognised as an avian parasite but is rarely reported as pathogenic. This paper describes severe disease in pigeons due to this parasite and is the first to describe the condition in Cyprus. The morphology of the parasite and the associated lesions are described and illustrated and the pathogenesis of the condition is discussed.
