The global research trend of porcine reproductive and respiratory syndrome virus (PRRSV): A mini review

The Porcine reproductive and respiratory syndrome (PRRS) is a significantly harmful illness in swine causing respiratory problems and reproductive failure in sows, gilts, and pneumonia in young pigs. PRRS is often diagnosed with available test methods to identify disease agent or to detect the immune response of virus. In spite of many extensive researches, there are still no specific treatments and many unknown relationships between this virus and other diseases in swine. Virus isolation and molecular techniques are possible to identify PRRS virus or its acid nucleic but the high genetic diversity of virus results to unwanted false-negative results. Although PRRS has spreads throughout the world, many researches still focus on updating the methods to quickly diagnose PRRSV and to generate an effective fast treatment. This review highlights the current global PRRS research trend, its detection and diagnosis.
