A Natural Recombinant PRRSV Between HP-PRRSV JXA1-Like and NADC30-Like Strains

Transboundary and Emerging Diseases, 2018
Porcine reproductive and respiratory syndrome virus (PRRSV) is a major economically significant pathogen that has adversely affected China's swine industry. Currently, a novel type 2 PRRSV, called the NADC30-like strain, is epidemic in numerous provinces of China, and commercial vaccines provide limited protection for infected animals.

Efficacy of concurrent vaccination with modified-live PRRSV-1 and PRRSV-2 vaccines against heterologous dual PRRSV-1 and PRRSV-2 challenge in late term pregnancy gilts

Veterinary Microbiology, 2019
The objective of this study was to evaluate the effect of concurrent vaccination with a porcine reproductive and respiratory syndrome virus (PRRSV)-1 modified-live virus (MLV) vaccine and a PRRSV-2 MLV vaccine against a dual heterologous PRRSV-1 and PRRSV-2 challenge in late term pregnancy gilts. Gilts were concurrently administered PRRSV-1 and PRRSV-2

PRRSV genetic variation after the 2010 HP-PRRSV introduction in Thailand

The Thai Journal of Veterinary Medicine, 2016
After the first introduction of porcine reproductive and respiratory syndrome virus (PRRSV) into Thailand, Thai type 1 PRRSV has existed in the Thai swine population and caused subclinical diseases while type 2 PRRSV, which most PRRSV isolates belong to, has caused moderate to severe diseases.

Arterivirus PRRSV

1998
Pigs were infected with the porcine respiratory and reproductive syndrome virus (PRRSV) by the oronasal route. We studied the development of histological lesions, sites of virus infection and of inflammatory infiltrates by quantitative evaluation of reactive cells. The animals developed a multifocal interstitial pneumonia.

Dynamics and evolution of porcine reproductive and respiratory syndrome virus (PRRSV) ORF5 following modified live PRRSV vaccination in a PRRSV-infected herd

Archives of Virology, 2013
The objective of this study was to investigate the dynamics and evolution of porcine reproductive and respiratory syndrome virus (PRRSV) ORF5 following the use of a modified live PRRSV (MLV) vaccine. A PRRSV-positive farm with coexistence of types 1 and 2 and no history of MLV vaccination was investigated.

Development of PRRSV-1 specific monoclonal antibody and detection of PRRSV-1 infection

Virology
Porcine reproductive and respiratory syndrome virus (PRRSV) are responsible for reproductive failure in sows and respiratory diseases in pigs, inflicting significant economic losses worldwide. Due to continuous mutation and recombination, PRRSV exhibit remarkable genetic diversity, necessitating detection methods capable of recognizing PRRSV-2 and/or ...

Presence of PRRSV in wild boar in Italy

Veterinary Record, 2006
SIR, – The wild boar ( Sus scrofa ) population in Italy has increased during the past 30 years, as it has in other European countries, such as Spain, France, Germany and Croatia. Direct or indirect contact between wild boar and domestic pigs ( Sus scrofa domesticus ) may occur occasionally ...

Mechanistic Insights into PRRSV Inhibition through CD163–SRCR5 Blockade by PRRSV/CD163-IN-1

The Journal of Physical Chemistry Letters
Porcine reproductive and respiratory syndrome virus (PRRSV) causes severe economic losses in the swine industry by targeting pulmonary alveolar macrophages via the CD163 receptor, particularly its SRCR5 domain. However, the molecular details of small-molecule inhibition at this interface remain unclear.

Packaged Heteroclite Subgenomic RNAs of PRRSV

2001
Porcine reproductive and respiratory syndrome virus (PRRSV) is a member of the Arteriviridae family of the Nidovirales (Meulenberg et al, 1993b; Nelsen et al., 1999). While the complete genomes of three PRRSV strains are known (Allende et al., 1999; Meulenberg et al., 1993; Nelsen et al., 1999), main questions remains to be elucidated concerning viral ...

PRRSV receptors and their roles in virus infection

Archives of Microbiology, 2015
Porcine reproductive and respiratory syndrome virus (PRRSV) has a restricted cell tropism and prefers to invade well-differentiated cells of the monocyte/macrophage lineage, such as pulmonary alveolar macrophages and African green monkey kidney cell line MA-104 and its derivatives, such as Marc-145, Vero and CL-2621.
