| Abstract: | With the use of the optical microscope and the electron microscope, the results through observing the histological structure and ultrastructure of lymphoid organ from Penaeus chinensis reveal that under the optical microscope, the lym- phoid organ consists of many occluded anastomosing tubules. between two tubules are lumens, which are composed of the endothelial cells and the stromal cells. The interstitial sinuses are abundant in lots of hemocytes. And under the electron microscope, the non-nuclear parts of the endothelial cells have processes toward the lumens. The stromal cells have a large number of Golgi apparatus and mitochondria, whose structure are very simple. Moreover, we found a spherical virus in lymphoid organ cells which has an envelope and a diameter of 70-100 nm. The morphological properties of this virus is similar to REO(Reoviridae). Most inclusion bodies are globose and there are no capsulae in outer layer. Infected by the virus, the cellular organs showed serious cytopathological changes, such as the partial dilation, disruption or even complete disappearance of the nuclear membrane, the oedema of the Golgi apparatuses and the endoplastic reticulum, and the disintegration or denaturation of the mitochondria cristae. Simultaneously, together with the virus, some my coplasma infected the cells too. |
