A 32-amino-acid deletion in the nonstructural protein 3-coding region of porcine epidemic diarrhea virus is associated with clinical attenuation in piglets
Since the global emergence of highly pathogenic genotype 2b (HP-G2b) porcine epidemic diarrhea virus (PEDV) strains in 2013, these viruses have become endemic in South Korea. During local outbreaks, novel HP-G2b PEDV variants containing a 32-amino acid deletion (DEL) in nonstructural protein 3 (nsp3), designated NSP3-D...
