Proposed bursa of fabricius weight to body weight ratio standard in commercial broilers
(Elsevier, 2015-09-01)
Several causes may induce change and atrophy in the bursa of Fabricius (BF). Databases on BF standards are available from published studies, however, updated references are needed to adjust the
BF ...
Transmission of severe acute respiratory syndrome coronavirus 2 from humans to animals: is there a risk of novel reservoirs?
(Elsevier, 2023-10-02)
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-
2) is a zoonotic virus able to infect humans and multiple
nonhuman animal species. Most natural infections in
companion, captive zoo, ...
Anti-PD-L1 Immunotherapy of Chronic Virus Infection Improves Virus Control without Augmenting Tissue Damage by Fibrosis
(MDPI, 2024-05-17)
Immunotherapy with checkpoint inhibitors, albeit commonly used against tumors, is
still at its infancy against chronic virus infections. It relies on the reinvigoration of exhausted T
lymphocytes to ...
A shift in Porcine circovirus 3 (PCV‐3) history paradigm: Phylodynamic analyses reveal an ancient origin and prolonged undetected circulation in the worldwide swine population
(Wiley Open Access, 2019-09-30)
The identification of a new circovirus (Porcine circovirus 3, PCV-3) has raised a remarkable concern because of some analogies with Porcine circovirus 2 (PCV-2). Preliminary results suggest an extremely ...
Infection dynamics of porcine circovirus type 3 in longitudinally sampled pigs from four Spanish farms
(BMJ Publishing Group, 2019-04-30)
Porcine circovirus type 3 (PCV-3) is a recently discovered virus in domestic pigs and wild boar. The virus has been described in pigs with different clinical/pathological presentations and healthy ...
Stable neutralizing antibody levels 6 months after mild and severe COVID-19 episodes
(Elsevier, 2021-01-31)
Background. Understanding mid-term kinetics of immunity to SARS-CoV-2 is the cornerstone for public health control of the pandemic and vaccine development. However, current evidence is rather based on ...
Detection of West Nile virus lineage 2 in North‐Eastern Spain (Catalonia)
(Wiley, 2018-12-01)
In September 2017, West Nile virus (WNV) lineage 2 was detected in Catalonia (Northern Spain) in northern goshawks by passive surveillance. The phylogenetic analyses showed that it was related to the ...
Ecological Factors Driving Avian Influenza Virus Dynamics in Spanish Wetland Ecosystems
(Public Library of Science, 2012-11-12)
Studies exploring the ecological interactions between avian influenza viruses (AIV), natural hosts and the environment are
scarce. Most work has focused on viral survival and transmission under laboratory ...
Identification of a Newly Conserved SLA-II Epitope in a Structural Protein of Swine Influenza Virus
(Frontiers Media, 2020-09-16)
Despite the role of pigs as a source of new Influenza A Virus viruses (IAV) potentially capable of initiating human pandemics, immune responses to swine influenza virus (SwIV) in pigs are not fully ...
Novel Spike-stabilized trimers with improved production protect K18-hACE2 mice and golden Syrian hamsters from the highly pathogenic SARS-CoV-2 Beta variant
(Frontiers Media, 2023-12-04)
Most COVID-19 vaccines are based on the SARS-CoV-2 Spike glycoprotein (S) or
their subunits. However, S shows some structural instability that limits its
immunogenicity and production, hampering the ...
