Abstract
The diagnostic performance of a commercial Mycoplasma hyopneumoniae (MHP) serum enzyme-linked immunosorbent assay (ELISA) was evaluated for MHP antibody detection in processing fluids (n = 494) using samples from three commercial swine farms. Based on historical monitoring, one farm was considered MHP positive and two were considered MHP negative. Samples were tested at a 1:10 dilution and diagnostic sensitivities and specificities estimated for specific ELISA sample-to-positive (S:P) cutoffs. At S:P ≥ 0.40, diagnostic sensitivity and specificity were estimated as 97.6% and 100.0%, respectively. Overall, the results suggest that processing fluids can be used for MHP antibody surveillance in breeding herds.
