摘要

During a 5-year period, 16 freshwater turtles (Trachemys scripta elegans and Chrysemys picta) that were purchased for research purposes died spontaneously. Clinical signs of disease included lethargy, constant swimming, swimming sideways, hemiplegiaand ulcerative lesions on the carapace. At necropsy, subcutaneous oedema, hepatic necrosis, pancreatic necrosis, splenic necrosis and intestinal parasites were identified. Histologically, trematode ova were seen within the liver, brain, spleen, kidney,myocardium, lung, pancreas, testes and bladder, and were associated with granulomatous reactions. The size and distribution of the ova were consistent with Spirorchis sp. infection, although adults could not be found to confirm this.
