Emergence and Reemergence of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV)
نویسندگان
چکیده
PRRSV has obsessed world pig industry for decades though the commercial vaccines and stamping-out policy have been widely used in many countries. So far, PRRSV is still prevalent in North America and most Asian countries and leads to huge economic losses. PRRSV is notorious for its quick rate of mutation and recombination that may lead to the change of virulence. A good example is the emergence of highly pathogenic PRRSV (HP-PRRSV) in 2006 that led to huge amount of economic losses in Chinese pig industry.

A molecular clock dates the common ancestor of European-type porcine reproductive and respiratory syndrome virus at more than 10 years before the emergence of disease.
The disease caused by porcine reproductive and respiratory syndrome virus (PRRSV) emerged independently and almost simultaneously in Europe (1990) and North America (1987). The original reservoir of the virus and the date it entered the pig populations is not known. In this study, we demonstrate an accurate molecular clock for the European PRRSV ORF 3 gene, place the root in the genealogy, esti...
متن کاملEmergence of a virulent porcine reproductive and respiratory syndrome virus (PRRSV) 1 strain in Lower Austria
BACKGROUND In spring 2015, an outbreak of porcine reproductive and respiratory syndrome (PRRS) struck Lower Austria caused by a PRRS virus (PRRSV) strain spreading rapidly among both previously PRRSV negative and vaccinated pig herds. This case report describes the first well-documented emergence of the PRRSV strain responsible for this outbreak. CASE PRESENTATION A PRRSV seronegative piglet-...

Porcine reproductive and respiratory syndrome virus (PRRSV) ORF5 and ORF7 sequences from Belarus were found to be of the European (EU) genotype, but grouped separately from all other EU genotype sequences described so far, including live-attenuated EU genotype PRRSV vaccines and Italian EU genotype sequences, some of which have been associated with reduced vaccine efficacy. Also, the Belarusian...
متن کاملGenome characterization of two NADC30-like porcine reproductive and respiratory syndrome viruses in China
BACKGROUND The recent emergence of NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) in vaccinated pigs arose more attentions for the high incidents of mutation and recombination of PRRSVs. FINDINGS In this study, we determined full-length genome sequences of two NADC30-like PRRSV isolates from recent PRRSV outbreaks in China. Phylogenetic analysis showed that these two ...
متن کاملPorcine Reproductive and Respiratory Syndrome Virus, Thailand, 2010–2011
Characterization of porcine reproductive and respiratory syndrome virus (PRRSV) isolates from pigs in Thailand showed 30-aa discontinuous deletions in nonstructural protein 2, identical to sequences for highly pathogenic PRRSV. The novel virus is genetically related to PRRSV from China and may have spread to Thailand through illegal transport of infectious animals from bordering countries.
