Comparison of four commercial PRRSV MLV vaccines in herds with co-circulation of PRRSV-1 and PRRSV-2

Comparative Immunology, Microbiology and Infectious Diseases, 2019
The efficacy of four commercial porcine reproductive and respiratory syndrome virus (PRRSV) modified-live virus (MLV) vaccines against respiratory disease was evaluated and compared in pig farms suffering from co-infection with PRRSV-1 and PRRSV-2.

Dual infections of PRRSV/influenza or PRRSV/Actinobacillus pleuropneumoniae in the respiratory tract

Veterinary Microbiology, 1997
To study the effect of a previous porcine respiratory and reproductive syndrome-infection (PRRS) of the respiratory tract on influenza virus and Actinobacillus pleuropneumoniae (App) infections, 3-week-old specific-pathogen-free (spf) piglets were intranasally infected with PRRS virus.

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

Antiviral Strategies against PRRSV Infection

Trends in Microbiology, 2017
PRRSV (porcine reproductive and respiratory syndrome virus) is a major economically significant pathogen that has adversely impacted the global swine industry for almost 30 years. Currently PRRSV is estimated to cause losses of almost US$600 million per year in the USA.

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.

A longitudinal study on PRRSV detection in swine herds with different demographics and PRRSV management strategies

Transboundary and Emerging Diseases, 2021
AbstractPorcine reproductive and respiratory syndrome virus (PRRSV) has been one of the major health‐related concerns in the swine production industry. Through its rapid transmission and mutation, the simultaneous circulation of multiple PRRSV strains can be a challenge in PRRSV diagnostic, control and surveillance.

Broad neutralization activity against both PRRSV-1 and PRRSV-2 and enhancement of cell mediated immunity against PRRSV by a novel IgM monoclonal antibody

Antiviral Research, 2020
Porcine reproductive and respiratory syndrome (PRRS) is the most economically important infectious disease affecting the global swine industry, especially since vaccination has had limited impact on PRRSV prevention and control. In this study, the monoclonal antibody PR5nf1 (Mab-PR5nf1, IgM isotype) was shown to react with heterogeneous PRRSV isolates ...

Syndecan-4, a PRRSV attachment factor, mediates PRRSV entry through its interaction with EGFR

Biochemical and Biophysical Research Communications, 2016
The causative agent of porcine reproductive and respiratory syndrome is the PRRS virus (PRRSV), an enveloped, single-stranded and positive-sense RNA virus. The host factors and mechanisms that are involved in PRRSV entry are still largely unknown.

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.

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.
