Materials and methods: A 4-L pool of swine oral fluid was collected from 16week-old finisher pigs. To ensure uniform, quantifiable levels of virus and antibody over time, 4 mL of PRRSV isolate ISU-P containing 1 × 1012 RNA copies per mL and 10 mL of concentrated hyperimmune anti-PRRSV antibodies were added to the pool. The pool was then divided into three equal portions: no treatment, chlorhexidine digluconate at 0.01% by volume, and isothiazolinone at 3 ppm. Each treatment was tested in… CONTINUE READING
