Whole genome–based phylogenetic analysis showed that these 67 PRRSVs could be divided into 4 subgroups
The epidemiologic data show that the outbreak of HP-PRRSV emerged from 1 particular place and spread widely. This evidence indicates that all HP-PRRSVs isolated in China likely originated from the same source
Summary
4. Araki K, Yoshimatsu K, Ogino M, Ebihara H, Lundkvist A, Kariwa H, et al Truncated hantavirus nucleocapsid proteins for serotyping Hantaan, Seoul, and Dobrava hantavirus infections. To the Editor: A highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV), which affected >2 million pigs, emerged in early 2006 in the People’s Republic of China. A number of HP-PRRSVs have been isolated from 2006 through 2009 from infected pigs in different provinces of China and confirmed to be the causative agent of the new outbreaks (1,2).
