The context-specificity of virulence evolution revealed through evolutionary invasion analysis [PDF]

arXiv, 2023
Models are often employed to integrate knowledge about epidemics across scales and simulate disease dynamics. While these approaches have played a central role in studying the mechanics underlying epidemics, we lack ways to reliably predict how the relationship between virulence (the harm to hosts caused by an infection) and transmission will evolve in

Dogs as potential carriers of infectious bursal disease virus [PDF]

Avian Pathology, 2004
In this study, the possibility that dogs could eventually be carriers of infectious bursal disease virus (IBDV) after having eaten (voluntarily or accidentally) IBDV-infected chicks has been evaluated. A single Beagle dog was fed chicks infected by a very virulent IBDV strain (vvIBDV).

Differential Expression of Mitogen-Activated Protein Kinase Kinase 3 (MAP2K3) and Interleukin12B (IL12B) in the Bursa of Fabricius of chicken infected with Infectious Bursal Disease Virus

Journal of Veterinary and Animal Sciences
Infectious Bursal Disease (IBD) caused by Infectious Bursal Disease virus (IBDV), poses a significant threat to the poultry industry, causing immunosuppression and economic losses since its discovery in 1957.

Comparison of the expression of cytokine genes in the bursal tissues of the chickens following challenge with infectious bursal disease viruses of varying virulence [PDF]

, 2010
BACKGROUND: Cytokines are important mediators and regulators of host responses against foreign antigen, with their main function to orchestrate the functional activities of the cells of the immune system.

UPLC‐ESI‐QTOF‐MS/MS Profiling, Antioxidant, and Cytotoxicity Potentials of Marrubium vulgare L. Extracts: Experimental Analysis and Computational Validation

Chemistry &Biodiversity, EarlyView.
ABSTRACT Plant extracts are emerging as valuable options for food additives and therapeutic treatments. This study evaluated the phytochemical profile, antioxidant activity, and cytotoxicity of aerial parts of Marrubium vulgare L. crude extract (MVCE) and its subfractions.

Molecular Characterization of Infectious Bursal Disease Virus Isolated from Naturally Infected Broiler Chickens in Erbil, Iraq

The Iraqi Journal of Veterinary Medicine, 2020
The infectious bursal disease (IBD) is a highly contagious and immunosuppressive disease of broiler chickens and the development of a new genetic variant of the virus is responsible for major economic losses in the poultry industry.

The effects of classic and variant infectious bursal disease viruses on lymphocyte populations in specific-pathogen-free White Leghorn chickens [PDF]

, 2003
Infectious bursal disease virus (IBDV) is a pathogen that primarily infects B lymphocytes in domestic avian species. This viral infection has been associated with immunosuppression, clinical disease/mortality, and enteric malabsorption effects.

Protection of Chickens against Very Virulent Infectious Bursal Disease Virus (IBDV) and Marek's Disease Virus (MDV) with a Recombinant MDV Expressing IBDV VP2 [PDF]

, 1999
To develop a herpes virus vaccine that can induce immunity for an extended period, a recombinant Marek's disease (MD) virus (MDV) CVI-988 strain expressing infectious bursal disease virus (IBDV) host-protective antigen VP2 at theUS2site (rMDV) was ...

PCFT‐Independent Cellular Uptake of Cyclic Cell‐Penetrating Peptide‐Conjugated Folic Acid

ChemBioChem, EarlyView.
Cell‐penetrating peptide (CPP)‐conjugated folic acid mediates efficient internalization of folic acid that is independent of the presence of proton‐coupled folate transporter (PCFT) on the intestinal cells. CPP‐conjugated folic acid demonstrates superior cellular uptake at all studied pH and in the presence of PCFT inhibitors and shows enhanced ...

DETECTION OF VARIANT STRAINS OF INFECTIOUS BURSAL DISEASE VIRUS IN BROILER FLOCKS IN SAUDI ARABIA USING ANTIGEN CAPTURE ENZYME-LINKED IMMUNOSORBENT ASSAY [PDF]

Pakistan Veterinary Journal, 2009
Infectious bursal disease conditions were observed in 15 commercial and 9 backyard broiler flocks in central area of Saudi Arabia during 2007-2008. The age of birds ranged from 2 to 8 weeks.
