Porcine reproductive and respiratory syndrome (PRRS) has become a major swine disease worldwide. Relevant management strategies and diagnostic assays are of importance for PRRS virus (PRRSV) control. The objective of this study was to determine the use of oral fluids for PRRSV monitoring in endemically PRRSV-infected herds. PRRSV RNA and PRRSV-specific antibodies were monitored using oral fluid samples and serum samples in two conventional swine farms in Thailand (‘Farm A’, a one-site conventional system farm, and ‘Farm B’, a one-site P0-P1 segregation system farm) during farrowing to nursery periods. Both PRRSV RNA and PRRSV antibodies were detected from 3 to …
