Restriction fragment length polymorphism analysis of isolates of infectious bursal disease viruses from Turkey

open access: yesVeterinární Medicína, 2003
Infectious bursal disease Virus (IBDV) specific reverse transcriptase/polymerase chain recation (RT/PCR) positive 40 broiler bursa fabricius samples obtained from a commercially reared flock were investigated for genetic diversity by PCR-RFLP assay.

Evaluation of secondary metabolites of herbal plant extracts as an antiviral effect on infectious bursal disease virus isolates in embryonated chicken eggs [PDF]

open access: yesVeterinary World, 2021
Background and Aim: Infectious bursal disease attacks the poultry industry, mainly young chickens, causing immunosuppression, and death with high economic losses. This study aimed to evaluate the effects of the monoextract, diextracts, and triextracts of

Viral proteins expressed in the protozoan parasite Eimeria tenella are detected by the chicken immune system [PDF]

open access: yes, 2016
BACKGROUND: Eimeria species are parasitic protozoa that cause coccidiosis, an intestinal disease commonly characterised by malabsorption, diarrhoea and haemorrhage that is particularly important in chickens.

Graphene‐Based Nanocomposites as Antibacterial, Antiviral and Antifungal Agents

open access: yesAdvanced Healthcare Materials, Volume 12, Issue 6, March 1, 2023., 2023
Over the past decade, there have been many interesting studies in the scientific literature about the interaction of graphene nanocomposites with microorganisms to tackle antimicrobial resistance. This article presents the antimicrobial mechanisms of graphene nanocomposites and demonstrates typical in‐vitro and in vivo studies on the use of graphene ...

A comparative study of acute phase protein concentrations in historical and modern broiler breeding lines [PDF]

open access: yes, 2018
Acute-phase proteins (APP) are secreted from the liver as a result of inflammation or infection and are measurable in serum and plasma. To determine whether the constitutive APP serum amyloid A (SAA), alpha-1-acid glycoprotein (AGP), ceruloplasmin (Cp ...

An Infectious Bursal Disease Virus (IBDV) Reverse Genetics Rescue System and Neutralization Assay in Chicken B Cells

open access: yesCurrent Protocols, Volume 3, Issue 1, January 2023., 2023
Abstract Infectious bursal disease virus (IBDV) is a major threat to the productivity of the poultry industry due to morbidity, mortality, and immunosuppression that exacerbates secondary infections and reduces the efficacy of vaccination programs. Field strains of IBDV have a preferred tropism for chicken B cells, the majority of which reside in the ...

Isolation and genomic characteristics of the novel variant infectious bursal disease virus in China

open access: yesFrontiers in Veterinary Science, 2023
The infectious bursal disease virus (IBDV) is a member of the viruses that can induce immunosuppression in chickens. In recent years, more and more IBDV-infected cases by the novel variant IBDV were reported in China, and it has been demonstrated that ...

The Stronger Downregulation of in vitro and in vivo Innate Antiviral Responses by a Very Virulent Strain of Infectious Bursal Disease Virus (IBDV), Compared to a Classical Strain, Is Mediated, in Part, by the VP4 Protein

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
IBDV is economically important to the poultry industry. Very virulent (vv) strains cause higher mortality rates than other strains for reasons that remain poorly understood. In order to provide more information on IBDV disease outcome, groups of chickens

Chicken PRMT3 facilitates IBDV replication. [PDF]

open access: yesPoult Sci
Protein arginine methyltransferases (PRMTs) in mammals play a role in various signaling pathways, such as virus infection, inflammasome responses, and cancer growth. While some PRMTs have been found to regulate interferon production in mammals, the mechanism in chickens remains to be fully understood. This study focused on investigating the function of

A Recombinant Newcastle Disease Virus (NDV) Expressing VP2 Protein of Infectious Bursal Disease Virus (IBDV) Protects against NDV and IBDV [PDF]

open access: greenJournal of Virology, 2004
ABSTRACT Infectious bursal disease virus (IBDV) causes a highly immunosuppressive disease in chickens. Currently available, live IBDV vaccines can lead to generation of variant viruses. We have developed an alternative vaccine that will not create variant IBDV. By using the reverse genetics approach, we devised a recombinant Newcastle disease
