High levels of unreported intraspecific diversity among RNA viruses in faeces of neonatal piglets with diarrhoea
(BMC, 2019-12-05)
BACKGROUND:
Diarrhoea is a major cause of death in neonate pigs and most of the viruses that cause it are RNA viruses. Next Generation Sequencing (NGS) deeply characterize the genetic diversity among ...
Swine Dendritic Cell Response to Porcine Reproductive and Respiratory Syndrome Virus: An Update
(Frontiers Media, 2021-07-28)
Dendritic cells (DCs) are the most potent antigen-presenting cells, unique to initiate and coordinate the adaptive immune response. In pigs, conventional DCs (cDCs), plasmacytoid DCs (pDCs), and ...
Development of an antigen Enzyme-Linked AptaSorbent Assay (ELASA) for the detection of swine influenza virus in field samples
(Elsevier, 2021-08-09)
Influenza viruses are highly variable pathogens that infect a wide range of mammalian and avian species. According to the internal conserved proteins (nucleoprotein: NP, and matrix proteins: M), these ...
Using commercial ELISAs to assess humoral response in sows repeatedly vaccinated with modified live porcine reproductive and respiratory syndrome virus
(BMJ Publishing Group, 2019-10-01)
Background Sows in breeding herds are often mass vaccinated against porcine reproductive and respiratory syndrome (PRRS) every few months using modified live vaccines (MLV). Field veterinarians repeatedly ...
Biosecurity in pig farms: a review
(BMC, 2021-01-04)
The perception of the importance of animal health and its relationship with biosecurity has increased in recent years with the emergence and re-emergence of several diseases difficult to control. This ...
Testing of umbilical cords by real time PCR is suitable for assessing vertical transmission of porcine reproductive and respiratory syndrome virus under field conditions
(Elsevier, 2018-02-01)
The objective of this study was to test the suitability of umbilical cord (UC) sampling and ear vein swabbing (EVS) as alternatives to jugular vein bleeding (JVB) for the assessment of vertical transmission ...
Characterization of homologous and heterologous adaptive immune responses in porcine reproductive and respiratory syndrome virus infection
(BMC, 2012-04-19)
The present study characterized the homologous and heterologous immune response in type-I porcine
reproductive and respiratory syndrome virus (PRRSV) infection. Two experiments were conducted: in ...
Impact of Cryopreservation on Viability, Phenotype, and Functionality of Porcine PBMC
(Frontiers Media, 2021-11-29)
The use of frozen peripheral blood mononuclear cells (PBMC) is common in immunological studies. The impact of freezing PBMC has been assessed using human and mice cells, but little information is available ...
Immunological Features of the Non-Structural Proteins of Porcine Reproductive and Respiratory Syndrome Virus
(MDPI, 2015-02-24)
Porcine reproductive and respiratory syndrome virus (PRRSV) is currently one of the most important viruses affecting the swine industry worldwide. Despite the large number of papers published each year, ...
Porcine reproductive and respiratory syndrome virus impacts on gut microbiome in a strain virulence‐dependent fashion
(Wiley Open Access, 2021-03-03)
Porcine reproductive and respiratory syndrome (PRRS) is a viral disease defined by reproductive problems, respiratory distress and a negative impact on growth rate and general condition. Virulent PRRS ...
