Complete Genome Sequence of a Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus Variant Isolated from a Backyard Piglet
Following the 2006 outbreaks of the highly pathogenic porcine reproductive and respiratory syndrome, the causative agent was identified as the highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV). To investigate whether the HP-PRRSV variant continues circulating and accelerating evolution, we sequenced and analyzed the complete genome of the identified HP-PRRSV field...
متن کاملDetecting PRRSV in boar semen
Since the initial outbreaks of porcine reproductive and respiratory syndrome (PRRS) in 1987 and subsequent identification of the causative virus in 1991, the primary concern of the swine industry has been the routes of PRRS virus (PRRSV) transmission. Initial epidemiological studies, particularly in Europe, indicated that airborne transmission, even over significant distances, was important. Ho...
متن کاملStructure of the nucleocapsid protein of porcine reproductive and respiratory syndrome virus.
Porcine reproductive and respiratory syndrome virus (PRRSV) is an enveloped RNA virus of the Arteriviridae family, genomically related to the coronaviruses. PRRSV is the causative agent of both severe and persistent respiratory disease and reproductive failure in pigs worldwide. The PRRSV virion contains a core made of the 123 amino acid nucleocapsid (N) protein, a product of the ORF7 gene. We ...
متن کاملPorcine Respiratory Disease Complex (prdc): a Review. I. Etiology, Epidemiology, Clinical Forms and Pathoanatomical Features
The porcine respiratory disease complex (PRDC) is a relatively new disease with rapidly increasing importance for the insdustrial intensive pig breeding. The main causative agent is Mycoplasma hyopneumoniae and secondary pathogens – the porcine reproductive and respiratory syndrome virus (PRRSV), swine influenza virus (SIV) and Actinobacillus pleuropneumoniae. The disease is primarily seen in l...
