Porcine reproductive and respiratory syndrome virus causes significant economic losses in the U.S. — approximately $1.2 billion annually — due to reproductive failure, abortion and high pre-weaning mortality among piglets. Thirty percent of the U.S. breeding herd experiences annual PRRSV outbreaks. A farm’s positive stable status is confirmed by sampling serum from piglets or using processing fluids.

Nasal microbial diversity is associated with survival in piglets infected by a highly virulent PRRSV‑1 strain
