Diversified Strains of Porcine Reproductive and Respiratory Syndrome Virus Circulating in China: A Mini-overview
Journal Title: Annual Research & Review in Biology - Year 2015, Vol 5, Issue 1
Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) was considered as an important pathogen, which caused huge economic losses for the world swine industry annually. Until now, according to antigenic and genetic characteristics, two genotypes were identified, European (EU genotype, or type 1) genotype and North American genotype (NA genotype, or type 2), respectively. In China, both of them co-existed in swine herds, and even some novel viral strains emerged in the lastest years. The aim of the review was to describe genetic diversity of PRRSV based on non-structural protein 2 (Nsp2) in China, which could help us better understand molecular epidemiology of PRRSV. Moreover, diversified strains of PRRSV circulating in Chinese swine herds might bring serious challenges to PRRS control for government, producers and veterinary practitioners.
