Fatal Strongyloidiasis in the Gibbon (Hylobates lar): A Report of 24 Cases.

摘要

A 6-year retrospective study of necropsy materials from a large gibbon colony revealed that stronglyloidiasis was the most important cause of death (24 cases). There were a variety of clinical signs: diarrhea, the most prevalent, occurred in 54% of the animals. Lesions were present most frequently in the lungs and the gastrointestinal tract. There were two lesions in the gut: erosive and ulcerative enteritis associated with the adult female parasites and rhabditiform larvae and acute and/or granulomatous enterocolitis associates with invading filariform larvae. Severe multifocal or diffuse hemorrhage associated with migrating larvae was present in the lungs of 23 animals. Filariform larvae and associated lesions also occurred in a variety of other tissues commensurate with the wide distribution of these larvae in the hyperinfection syndrome. (Author)
