1. Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) is a significant pathogen in the swine industry, causing reproductive failure in sows and respiratory disease in piglets.
2. PRRSV has a complex interaction with the immune system, evading host defenses and modulating immune responses. This contributes to the persistence and spread of the virus within pig populations.
3. Understanding the viral pathogenesis and immune responses to PRRSV infection is crucial for developing effective control strategies, such as vaccines, to mitigate the impact of this economically important disease.
