BMC Veterinary Research 24/05/19 Genetic analysis of porcine productive and respiratory syndrome virus between 2013 and 2014 in Southern parts of China: identification of several novel strains with amino acid deletions or insertions in nsp2. Since its emergence in China at the end of 1995, PRRSV has spread widely in all areas of China and is continuously evolving.
This has led to the emergence of some new antigenic variant strains . In 2006, a large outbreak of porcine high fever syndrome (PHFD), caused by a highly pathogenic form of PRRSV, emerged in China and Southeast Asian countries and caused major economic losses for swine farming [12, 15, 16] . In our previous study, 133 of 475 samples (28%) were positive for PRRSV, indicating that PRRSV is widely distributed among swine populations in southern parts of China. Fifty-six ORF5 sequences and 35 nsp2 HVR sequences were selected for investigation of variations and phylogenetic analyses for their genetic diversities.
Our data would contribute to epidemiology investigation of PRRSV and have some implications for vaccine development. Abstract. VIROLOGY JOURNAL 04/01/18 The prevalent status and genetic diversity of porcine reproductive and respiratory syndrome virus in China: a molecular epidemiological perspective. Porcine reproductive and respiratory syndrome (PRRS) is one of the most important economically diseases to the swine industry worldwide.
It is estimated that the total economic losses caused by PRRS is about $664 million annually in the America, an increase from the $560 million annual cost estimated in 2005 . AASV 15/02/17 Emergence of a Novel Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus in China. February 15, 2017 — From 2014 to 2015, four novel highly pathogenic PRRS virus (HP-PRRSV) strains named 14LY01-FJ, 14LY02-FJ 15LY01-FJ, and 15LY02-FJ were isolated from high morbidity (100%) and mortality (40%-80%) in piglets and sows in Fujian Province.
To further our knowledge about these novel virus strains, we characterized their complete genomes and determined their pathogenicity in piglets. Full-length genome sequencing analysis showed that these four isolates were closely related to type 2 (North American type, NA-type) isolates, with 88.1%-96.3% nucleotide similarity, but only 60.6%-60.8% homology to the Lelystad virus (LV) (European type, EU-type). The full length of the four isolates was determined to be 15017 or 15018 nucleotides (nt), excluding the poly(A) tail.

Serologic assessment of domestic and wild animal populations near the residence of 1 of these persons showed high exposure rates to raccoons, white-tailed deer, and horses. To our knowledge, no laboratory-based assessments of viremic potential of animals infected with HRTV have been performed. We experimentally inoculated several vertebrates (raccoons, goats, chickens, rabbits, hamsters, C57BL/6 mice, and interferon-α/β/γ receptor–deficient [Ag129]) mice with this virus. All animals showed immune responses against HRTV after primary or secondary exposure. However, neutralizing antibody responses were limited.

A highly pathogenic swine disease designated as ‘porcine high fever disease (PHFD)’ appeared recently in China.
Porcine reproductive and respiratory syndrome virus (PRRSV) was identified as an agent associated with PHFD, and two discontiguous sequence deletions were identified as a genetic marker in the Nsp2 region of the viral genome. To examine PHFD in Shandong province, a total of 10 PRRSV isolates were recovered from pig herds that had never been vaccinated for PRRS. Sequence analysis of open reading frame 5 (ORF5) showed that the level of identity among the 10 isolates ranged between 88.2 and 99.2%.
