a
Swine influenza virus has been confirmed by PCR to be H3N2 virus
b
Confirmed by PCR on the 3rd passage of cell culture supernatants
c
Only PCV-2 was isolated in PKISA cells and it was confirmed by PCR at the 3rd passage
PCV-2 = porcine circovirus 2, TGEV/PRCV = transmissible gastroenteritis virus/porcine respiratory coronavirus, PRRSV = porcine reproductive and respiratory syndrome virus, SIV = swine influenza virus, PPV = porcine parvovirus, swHEV = swine hepatitis E virus, swTTV = swine torque teno virus, HRT-G = human rectal tumor cells, MDCK = Madin-Darby canine kidney cells, ST = swine testis cells, PK15A = porcine kidney cells
