【摘要】 利用组织切片法研究了斑节对虾杆状病毒 (MBV)在养殖早期斑节对虾及养成期斑节对虾中肠腺各部位的分布特点。斑节对虾的中肠腺可分为头部、亚头部、中部、亚尾部和尾部等 5个部分 ,其上皮细胞包括E细胞、F细胞、B细胞和R细胞等 4种类型。头部和尾部均以E细胞为主 ,亚头部、中部和亚尾部均以R细胞为主。在感染度较轻的样本中 ,MBV一般只感染F细胞、R细胞和B细胞。感染度较重时 ,E细胞也同时受累。在养殖早期虾和养成期虾中 ,MBV相对感染度在中肠腺各部分的分布均以中部最高 ,而且以中部的中间最高 ,离中部越远 ,相对感染度越低更多还原

【Abstract】 The distribution of Penaeus monodon baculovirus (MBV) in different parts of mid gut gland in juvenile and adult shrimp Penaeus monodon was studied by light microscopy. The mid gut gland of Penaeus monodon can be divided into five parts including head part, subhead part, mid part, subtail part and tail part. The cells of mid gut gland can be divided into E cell, R cell, B cell and F cell. The E cell was the main cells of the head part and the tail part. R cell was the main cells of the subhead part, the mid part and the subtail part. In the cases that infected lightly with MBV, only R cell, B cell and F cell were infected. In the cases that infected severely with MBV, besides R cell, B cell and F cell, E cell also was infected. Both juvenile and adult P. monodon, MBV distributed mainly in the mid part of mid gut gland and especially in the middle of mid part . The farther apart from the mid part, the lower the MBV infection rate was.更多还原
