A cDNA clone of a genotype 4 swine hepatitis E virus (HEV) strain (SAAS-FX17), identified in Shanghai, has been constructed. Capped RNA transcripts were prepared in vitro and shown to be replication-competent in Huh7 cells. Sprague-Dawley (SD) rats administered the RNA transcripts by intrahepatic inoculation developed active infections as evidenced by fecal virus shedding and sero-conversion to anti-HEV. The former was first detected between 23 and 30 days post-inoculation (dpi) and persisted until 45Â dpi. Sera of rats inoculated with RNA transcripts became anti-HEV positive between 30 and 40Â dpi, and reverted to anti-HEV negative at 52Â dpi. Our data indicate for the first time that intrahepatic inoculation of rats with RNA transcripts of an HEV cDNA clone may serve as an alternative animal model for HEV research.
