天津地区中国对虾杆状病毒初探

PRELIMINARY STUDY ON GRANULOSIS VIRUS DISEASE OF Penaeus chinensis IN TIANJIN AREA

１９９３年夏，发现天津地区人工养殖的中国对虾（Ｐｅｎａｅｕｓｃｈｉｎｅｎｓｉｓ）肝胰腺中有具包膜的短杆状病毒粒子。其大小明显不等，短径８０—１００ｎｍ，长径２００—２８０ｎｍ。病毒粒子寄生在肝胰腺管壁肌细胞和腺管之间的间质细胞核内，致使宿主肝胰腺超微结构发生严重病理改变。

In summer of 1993 ,We found some granulosis virus in the liver of pancreas Penaeus chinensis,which is cultivated artificially in Tianjin. This kind of virus appears short-rodshaped and is encysted by coat and pocket. The size of particles is obviously not equal ,and they vary from 80 to 100nm in short axis and from 200 to 280 nm in long axis. These virus particles are parasitized in the cytoblasts of the interstitial cells ,which are between the myocytes and glands ducts on the walls of the hepatic ,pancreatic ducts. Because of their exist ,some serious pathological changes have occurred in the ultrastructure of liver and pancrease of the host.
