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

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
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 ...

Vaccine‐Associated Recombination and Virulence Heterogeneity of GI‐19 (QX Type) Infectious Bronchitis Virus in Eastern and Southern China, 2024−2025

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Infectious bronchitis (IB) virus (IBV) remains a major pathogen threatening the poultry industry. Its rapid mutation and recombination continuously generate variants that disseminate worldwide. Between May 2024 and February 2025, 49 field strains were isolated from chickens vaccinated with live‐attenuated IBV vaccines (H120, 4/91, or QXL87) in four ...

Beyond FoxP3—Identification of a Chicken Regulatory T Cell Signature

European Journal of Immunology, Volume 55, Issue 12, December 2025.
Chicken FOXP3+ putative regulatory T cells were identified using both bulk and single‐cell RNA sequencing to define their transcriptional signature and flow cytometry to confirm surface marker expression. This combined approach revealed a distinct putative Treg subset characterized by CD4, CD25, and GITR surface expression. ABSTRACT Regulatory T cells (

The Power of Yeast

Yeast, Volume 42, Issue 12, Page 303-310, December 2025.
ABSTRACT Yeasts have been intimately connected with human civilization for millennia, originally used for fermentation in food and beverage production. This article explores the multifaceted roles of yeasts—particularly Saccharomyces cerevisiae—as both a model organism and a cell factory.
