Rapid Spread of Novel Infectious Bursal Disease Virus Variant (Genotype A2dB1b) in the Near East and Persian Gulf Regions: Molecular Surveillance and Phylodynamic Reconstruction. [PDF]

open access: yesTransbound Emerg Dis
Infectious bursal disease virus (IBDV) is one of the most impactful pathogens of poultry, with disease manifestations ranging from acute forms to subclinical but immunosuppressive infections. This heterogeneity, accompanied by a significant antigenic variability, is sustained by high mutation rates and frequent reassortments between the two genome ...

Susceptibility of Gecko Cell Line for Cultivation and Adaptation of Infectious Bursal Disease Virus as an Experimental Vaccine. [PDF]

open access: yesVet Med Sci
First successful cultivation of IBDV on reptile‐derived Z1 cells yields high‐titre virus and induces immunity in chickens. This scalable, egg‐free platform offers a promising alternative for vaccine production, leveraging evolutionary kinship between reptiles and birds for next‐generation poultry disease control.

Reassortant viruses threatening fish aquaculture

open access: yesReviews in Aquaculture, Volume 15, Issue 4, Page 1720-1731, September 2023., 2023
Abstract Aquaculture provides more than half of fish destined for human consumption worldwide. In aquaculture, infectious diseases triggered by viruses are amongst the major cause of mortality of farmed fish. The cohabitation of different virus strains in the same geographical area opens the possibility to natural reassortment.

Assessment of listing and categorisation of animal diseases within the framework of the Animal Health Law (Regulation (EU) No 2016/429): infectious pancreatic necrosis (IPN)

open access: yesEFSA Journal, Volume 21, Issue 6, June 2023., 2023
Abstract Infectious pancreatic necrosis (IPN) was assessed according to the criteria of the Animal Health Law (AHL), in particular, the criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9, and Article 8 for ...

Protein cargo encapsulation by virus‐like particles: Strategies and applications

open access: yesWIREs Nanomedicine and Nanobiotechnology, Volume 15, Issue 3, May/June 2023., 2023
Examples of non‐enveloped virus‐like particles used for the encapsulation of heterologous proteins. Abstract Viruses and the recombinant protein cages assembled from their structural proteins, known as virus‐like particles (VLPs), have gained wide interest as tools in biotechnology and nanotechnology.

Differential response of RTGUTGC and RTGILL‐W1 rainbow trout epithelial cell lines to viral stimulation

open access: yesJournal of Fish Diseases, Volume 46, Issue 4, Page 433-443, April 2023., 2023
Abstract Mucosal surfaces constitute the main route of entry of pathogens into the host. In fish, these mucosal tissues include, among others, the gastrointestinal tract, the gills and the skin. However, knowledge about the mechanisms of regulation of immunity in these tissues is still scarce, being essential to generate a solid base that allows the ...

Improving tilapia biosecurity through a value chain approach

open access: yesReviews in Aquaculture, Volume 15, Issue S1, Page 57-91, February 2023., 2023
Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.

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 ...

Comparative Safety, Immunogenicity, and Efficacy of CEF Cell‐Based and DF‐1 Cell Line Adapted Infectious Bursal Disease Vaccines in Specific‐Pathogen‐Free Chickens

open access: yesJournal of Immunology Research, Volume 2022, Issue 1, 2022., 2022
Infectious bursal disease (IBD) is an immunosuppressive and economically important disease of young chickens caused by infectious bursal disease virus (IBDV). The National Veterinary Institute (Bishoftu, Ethiopia) produces intermediate IBDV vaccine using primary chicken embryo fibroblast (CEF) cells, a method with technical and economical cumbersome ...
