Exchange of the C-terminal part of VP3 from very virulent infectious bursal disease virus results in an attenuated virus with a unique antigenic structure

, 2002
Infectious bursal disease virus (IBDV) is the major viral pathogen in the poultry industry. Live attenuated serotype 1 vaccine strains are commonly used to protect susceptible chickens during their first 6 weeks of life. Wild-type serotype 1 IBDV strains

Transcriptomic Analysis of Inbred Chicken Lines Reveals Infectious Bursal Disease Severity Is Associated with Greater Bursal Inflammation In Vivo and More Rapid Induction of Pro-Inflammatory Responses in Primary Bursal Cells Stimulated Ex Vivo

Viruses, 2021
In order to better understand differences in the outcome of infectious bursal disease virus (IBDV) infection, we inoculated a very virulent (vv) strain into White Leghorn chickens of inbred line W that was previously reported to experience over 24% flock

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Structural and growth characteristics of infectious bursal disease virus [PDF]

Journal of Virology, 1976
The infectious bursal disease virus is not enveloped and has a diameter of 60 nm and a density of about 1.32 g/ml. It contains two pieces of single-stranded RNA with molecular weights close to 2 X 10(6). The capsid is made up of four major polypeptides with molecular weights of 110,000, 50,000, 35,000, and 25,000. The virus replicates in chicken embryo

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.
