摘要

Ante-mortem detection of Mycoplasma hyopneumoniae (Mhp) can be difficult during the early stages of an infection. There is a need for accurate diagnostic sampling protocols to confidently determine if populations are negative (< 1% prevalence), remainnegative (< 1% prevalence) over time, and to detect early infection to prevent spread. In a recent study, the authors demonstrated with the use of stochastic modeling and diagnostic sensitivities (DxSe) that increased sample size resulting from ante-mortem laryngeal swab sampling combined with pooling allowed for a higher herd detection rate by PCR while pursuing the most economical approach, in a high prevalence population.' To further test this model in a Mhp low prevalence population scenario, a second study was designed. The objective of this study was to determine ante-mortem laryngeal swab sampling protocols for detection of Mhp by PCR at low prevalence levels.
