Fig. 2From: A new PEDV strain CH/HLJJS/2022 can challenge current detection methods and vaccinesA Plot the one-step growth curve of the virus. B Infection by the isolated viruses passaged up to passage 12 was observed microscopically for 60 h. C ORF3 recombinant plasmids were prepared to generate a standard curve. D Viral load assays were performed at 60 h, 72 and 84 h of CH/HLJJS/2022 infection (n = 3, P > 0.005)Back to article page
