PCR has been applied to detecting the outbreak virus diseases for the Penaeus chinensis cultured in China in recent years.

This paper is designed to identify the route of infection and the pathogenic organisms for explosive epidemic disease of red swamp crayfish,Procambarus clarkii.

The violent fish disease occured from April to November in Yangqi Lake, and experiments ascertained that environmental factors deterioration in the lake was the cause of the fish disease.

Objective: According to the brain-intestinal connection theoretics,to carry out the experimental study of kaiqiao and tongfu treating virosis fever,discuss the antifebrile effect of niuhuang chengqi tang to virosis fever,study the function and significance of brain-intestinal peptide and immunoregulation to virosis fever,show the essential of kaiqiao and tongfu treating virosis fever.

Effects of non biologic environmental factors on Penaeus chinensis infected by the explosive epidemic disease virus;

Abstract:Under the light microscope and the transmission electron microscope, the gill tissue on Penaus chinensis infected by the explosive epidemic disease was observed.

In order to study the infectious way and pathogenic mechanism of the explosive epidemic disease,artificial infection was carried out,and stomach infected was observed under light and electron microscopes.
