| whole genome characterization of a novel porcine reproductive and respiratory syndrome virus 1 isolate: genetic evidence for recombination between amervac vaccine and circulating strains in mainland china. | genotype 1 porcine reproductive and respiratory syndrome virus (prrsv 1) have been continuously isolated in china in recent years. complete genome sequences of these isolates are important to investigate the prevalence and evolution of chinese prrsv 1. herein, we describe the isolation of a novel prrsv 1 isolate, denominated hljb1, in the heilongjiang province of china. complete genome sequencing of hljb1 showed that it shares 90.66% and 58.21% nucleotide identities with prrsv 1 and 2 prototypic ... | 2017 | 28746838 |
