Construction and characterization of a full-length cDNA infectious clone of emerging porcine Senecavirus A
文摘

An infectious clone, pKS15-01-Clone, of newly emerging strain of SVA was constructed.

Cloned virus replicated efficiently in vitro and in vivo.

Cloned virus induced similar immunological response as that of parental virus.

EGFP-tagged SVA showed impaired replication ability and attenuated pathogenic properties.

Lesions on pig snout and coronary bands produced by parental virus, but not by cloned or EGFP-tagged virus.
