Abstract

Encephalomyocarditis virus (EMCV) infects animals of various species and causes a variety of clinical symptoms. In this study, an infectious full-length cDNA clone was constructed, and the characteristics of the rescued virus were investigated in vitro and in vivo. Our data demonstrated that the growth kinetics in vitro and plaque morphology of the rescued EMCV rNJ08 strain were similar to those of the parental strain. Although rNJ08 infected BALB/c mice, none of the mice died during the observation period of 14 days post-inoculation. The availability of the infectious cDNA clone provides a genetic platform for studying gene function and for the rational design of vaccines.
