Efficacy of a live attenuated vaccine in classical swine fever virus postnatally persistently infected pigs
(BMC, 2015-07-09)
Classical swine fever (CSF) causes major losses in pig farming, with various degrees of disease severity. Efficient live attenuated vaccines against classical swine fever virus (CSFV) are used routinely ...
Postnatal Persistent Infection with Classical Swine Fever Virus and Its Immunological Implications
(Public Library of Science, 2015-05-04)
It is well established that trans-placental transmission of classical swine fever virus (CSFV) during mid-gestation can lead to persistently infected offspring. The aim of the present study was to ...
Removal of the Erns RNase Activity and of the 39 Untranslated Region Polyuridine Insertion in a Low-Virulence Classical Swine Fever Virus Triggers a Cytokine Storm and Lethal Disease
(American Society for Microbiology, 2022-06-27)
In this study, we assessed the potential synergistic effect of the Erns RNase activity and the poly-U insertion in the 3′ untranslated region (UTR) of the low-virulence classical swine fever virus (CSFV) ...
A neutralizing monoclonal antibody-based competitive ELISA for classical swine fever C-strain post–vaccination monitoring
(BMC, 2020-01-14)
Background: Virus neutralization test (VNT) is widely used for serological survey of classical swine fever (CSF) and efficacy evaluation of CSF vaccines. However, VNT is a time consuming procedure that ...
Causes of cetacean stranding and death on the Catalonian coast (western Mediterranean Sea), 2012-2019
(Inter Research, 2020-12-17)
The causes of cetacean stranding and death along the Catalan coast between 2012 and 2019 were systematically investigated. Necropsies and detailed pathological investigations were performed on 89 ...
Investigation of chronic and persistent classical swine fever infections under field conditions and their impact on vaccine efficacy
(BMC, 2019-07-15)
Background: Recent studies have hypothesized that circulation of classical swine fever virus (CSFV) variants when the immunity induced by the vaccine is not sterilizing might favour viral persistence. ...
Evaluation of a Phylogenetic Marker Based on Genomic Segment B of Infectious Bursal Disease Virus: Facilitating a Feasible Incorporation of this Segment to the Molecular Epidemiology Studies for this Viral Agent
(Public Library of Science, 2015-05-06)
Background
Infectious bursal disease (IBD) is a highly contagious and acute viral disease, which has caused high mortality rates in birds and considerable economic losses in different parts of the world ...
Evolution of Swine Influenza Virus H3N2 in Vaccinated and Nonvaccinated Pigs after Previous Natural H1N1 Infection
(MDPI, 2022-09-10)
Swine influenza viruses (SIV) produce a highly contagious and worldwide distributed
disease that can cause important economic losses to the pig industry. Currently, this virus is endemic
in farms and, ...
Decrypting the Origin and Pathogenesis in Pregnant Ewes of a New Ovine Pestivirus Closely Related to Classical Swine Fever Virus
(MDPI, 2020-07-17)
This study shows the origin and the pathogenic role of a novel ovine pestivirus (OVPV) isolated in 2017 in Italy, as a pathogenic agent causing severe abortions after infection in pregnant ewes and high ...
Multi-Target Strategy for Pan/Foot-and-Mouth Disease Virus (FMDV) Detection: A Combination of Sequences Analysis, in Silico Predictions and Laboratory Diagnostic Evaluation
(Frontiers Media, 2018-07-12)
Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting cloven-hoofed animals that causes severe economic losses. The disease is characterized by a vesicular condition and it cannot ...
