外来与新发动物疫病猪繁殖与呼吸综合征病毒NADC30-like变异流行情况及综合防控措施

The Epidemic Situation and Control Measures of NADC 30-like Strains of Porcine Reproductive and Respiratory Syndrome Virus

猪繁殖与呼吸综合征在我国流行已20余年,但其病原变异的复杂程度在进一步加大,流行程度也并未明显减弱,特别是2013年以来NADC 30-like毒株的出现导致了PRRS再次大范围流行。近年来PRRSV重组变异毒株越来越多,因此了解其流行情况以及防护措施,对进一步防控该病及保障我国生猪健康养殖具有重要意义。

Porcine Reproductive and Respiratory Syndrome has been prevalent in China for more than 20 years.However,the complexity of its pathogenic mutation is still increasing,and the prevalence of pathogens has not decreased significantly.In particular,since 2013,the emergence of NADC 30-like strains has caused PRRS to spread widely again.Since the recombination mutation of PRRSV strains has been increasing in recent years,understanding its epidemic situation and protective measures,is of great importance to further prevent and control the disease and ensure the healthy breeding of pigs in China.
