ABSTRACT
Objective To evaluate the influences of high hydrostatic pressure (HHP) on the virulence and antigenicity of Coxsackie virus B3 (CB3 V) , to explore a new physiological method to develop an active vaccine against Coxsackie virus. Methods The phagocytosis of the macrophages in mice to the CB3 V and the TCID50 of the CB3V before and after treated by HHP were examined. Results TCID50 increased from 10-5 to 10-4 when treated by 680 MPa; viruses were inactivated at 700 MPa. Viruses were also inactivated by the pressure less than 700 MPa, but needed prolonged time. The phagocytic function, antibody and T lymphocyte transformation rate in experimental mice (heated, attenuated, and inactive viruses) exhibited a significant difference compared with control mice (P
