Abstract:

Porcine reproductive and respiratory syndrome (PRRS) is an infectious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV), which is mainly characterized by respiratory symptoms in pigs and reproductive failures in sows. PRRS has led to huge economic losses to the global swine industry. However, there is still no safe and effective vaccine or drug against PRRS. A comprehensive and in-depth understanding of the PRRSV life cycle can provide new ideas for PRRS prevention and control. Therefore, based on a brief description of the PRRSV life cycle, this paper focuses on the research progress of viral invasion, replication and transcription, translation and post-translational modification, assembly, with a view to providing a reference for the study of PRRSV pathogenic mechanism, prevention and control.

Key words: porcine reproductive and respiratory syndrome virus, invasion, replication and transcription, translation and post-translational modification, assembly
