【Abstract】 The principal histopathological changes of Chinese shrimp contracted blue-liver disease consisted of the following aspects:(1)A portion of gland cell neuclei in hepatopancreas greatly enlarged and stained strongly in deep purple. (2)Most of gland cells extremely intumescent, cytoplasm cystose and vacuolose in. The nucleus showing pycnosis and small and was packed to cell edge. (3)The homogeneous and pink-staining cruentatus eosinophilic body could be seen in cytoplasm of a few gland cell. The histopathological changes were consistent with the cytopathological changes in diseased shrimp. EM observation showed that the round virus in gland cell of hepatopancreas is the main pathogen of blue-liver disease. In addition, some cytopathological changes observed from ultrathin section were similar to the poisoning reaction in body caused by some factors.更多还原
