Probability of detecting PRRS V infection using pen-based swine oral fluid specimens as a function of within-pen prevalence

摘要

In swine populations surveillance for infectious diseases is often limited by the cost and labor associated with the collection individual pig samples. Recently, oral fluid samples have been shown to be an effective method for detection of PRRSV,3,4 influenza virus,1 PCV2,4 and other pathogens. Oral fluid sampling may provide advantages over collecting and testing individual samples but assay performance using pen-based samples has not been tested. The objective of this study was to determine the probability of detecting PRRSV infection using one pen-based oral fluid sample from pens of known PRRSV prevalence.
