Research Progress of Porcine Reproductive and Respiratory Syndrome
Abstract
Porcine Reproductive and Respiratory Syndrome (PRRS) is caused by Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), which is characterized by sow reproductive disorder and piglet respiratory syndrome. The complex pathogenesis of PPRS includes antibody-dependent enhancement, immune suppression and persistent infection in the body and viral genetic diversity. In order to have a better understanding of the occurrence and prevalence of porcine reproductive and respiratory syndrome in China. The review of PRRS etiology, epidemiology, pathogenesis, genetic variation, diagnosis and control technology and other aspects of the progress were carried out.References
