中华鳖稚鳖白斑病组织病理学研究OA

To explore the pathological lesion characteristics of white spot disease and its impacts on the tissues and organs of Pelodiscus sinensis,healthy juvenile turtles were set as the control group and naturally diseased individuals with white spot disease as the experimental group in this study.Conventional paraffin sectioning and hematoxylin-eosin(H.E.)staining were applied for histopathological observation on the skin,liver and kidney tissues of turtles in both groups.The results revealed that tissues and organs of the control group maintained complete structure with regularly arranged cells and no obvious pathological damage.In contrast,the white spot disease group showed severe pathological lesions in the epidermis and disordered muscle fibers,hepatocytes presented karyopyknosis and rupture,along with renal tubular epithelial cell necrosis,glomerular atrophy and inflammatory cell infiltration.This study demonstrates that white spot disease of P.sinensis is not merely confined to superficial local lesions,can cause multi-organ damage to the liver and kidneys.The research findings can provide reliable histopathological references for the diagnosis,prevention and control of white spot disease in P.sinensis.
