Abstract excerpt
Porcine epidemic diarrhea virus (PEDV) poses a great threat to the Chinese swine industry. During 2006-2011, 74.0 % (94/127) of samples from 32 swine-raising farms in 15 provinces were positive for PEDV by reverse transcription nested polymerase chain reaction (RT-nested PCR). The sequences of nucleocapsid (N) genes of 32 representative field strains were determined, and the open reading frames (ORFs) of these N...
