应用石蜡切片技术对斑节对虾杆状病毒（ Ｍ Ｂ Ｖ） 和肝胰腺细小样病毒（ Ｈ Ｐ Ｖ） 在斑节对虾、日本对虾和中国对虾中的感染情况进行了研究结果表明： Ｍ Ｂ Ｖ 在斑节对虾的仔虾、稚虾及养成期虾中的感染率均接近１００ ％ ；在日本对虾养成期虾中平均感染率为７５０ ％ ；中国对虾仔虾未检出 Ｍ Ｂ Ｖ 包涵体 Ｈ Ｐ Ｖ 在中国对虾仔虾中感染率为５６００ ％ ；在斑节对虾仔虾中感染率为２８７５ ％ ，稚虾为３６１１ ％ ，养成期虾平均为６５２５ ％ ；日本对虾养成期虾的平均感染率为２０００ ％  Ｍ Ｂ Ｖ 与 Ｈ Ｐ Ｖ 在斑节对虾中可出现合并感染的情况，其合并感染率为：仔虾２８５７ ％ ，稚虾３５６８ ％ ，养成期虾６４５４ ％ 日本对虾和中国对虾中未发现 Ｍ Ｂ Ｖ 与 Ｈ Ｐ Ｖ 合并感染的现象结果表明， Ｍ Ｂ Ｖ 是斑节对虾的主要病原体，而 Ｈ Ｐ Ｖ 是中国对虾的主要病原体 The paraffin section was used to study the infection of M. bovis (M B V) and hepatopancreas parvovirus (H P V) in P. monodon, P. japonicus and P. chinensis. The results showed that M B V in shrimp Penaeus monodon larvae, juvenile shrimp and developmental shrimp in the infection rates were close to 100%; shrimp in Japan during the breeding period the average infection rate was 750%; Penaeus chinensis did not detect M The infection rate of B V inclusion body H P V was 5600% in Chinese shrimp larvae. The infection rate was 2875% in Penaeus monodon and 3611% in juvenile shrimp, Was 6525%. The average infection rate of Japanese shrimp in developing stage was 2000%. M B V and H P V were likely to be co-infected in Penaeus monodon. The combined infection rate was:  57%, 3568% of juvenile shrimp, 6454% of developing shrimp  The infection of M B V and H P V was not observed in Japanese shrimp and Chinese shrimp  The results showed that M B V is the main pathogen of P. monodon and H P V is the major pathogen of P. shrimp
