Detection of PCV2 and anti-PCV2 antibodies in porcine oral fluid samples

摘要

Previous studies demonstrated the use of pen-based oral fluids for the surveillance of PRRSV, PCV2, and other pathogens. The objective of this research was to describe the excretion patterns of PCV2 and anti-PCV2 antibody in oral fluid samples from experimentally inoculated pigs. The onset, level, and duration of qPCR-detectable PCV2 and anti-PCV2 antibody in serum and oral fluid was evaluated over time. Eleven week-old animals were housed in four rooms, with each treatment group of 6 pigs in a separate room.
