title: Proventricular nematodiasis in wrinkled hornbills (Aceros corrugatus).
abstract: Three immature Sunda wrinkled hornbills (Aceros corrugatus) were diagnosed postmortem with proventricular spirurid nematodiasis. Concurrent severe disseminated larval granulomatosis in other visceral organs was considered contributory to mortality in each case. Clinical signs of nematodiasis were vague but generally consisted of weight loss, anorexia, and lethargy. Frequent antemortem fecal examinations were negative for spirurid eggs. In these present cases, based on routine histopathology, both prophylactic and empirically based therapeutic anthelmintic treatments had no evident benefit in the elimination of the proventricular nematodes. Spirurid nematodiasis may be an important cause of mortality in young hornbills.
