Chicken Infectious Anemia Virus Markedly Enhances the Pathogenicity of Infectious Bronchitis Virus-Infected Chickens. [PDF]

Transbound Emerg Dis
Chicken infectious anemia virus (CIAV) and infectious bronchitis virus (IBV) represent two of the most economically significant pathogens in the global poultry production. In recent years, coinfections involving CIAV and IBV have become increasingly prevalent in clinical scenarios across Southern China and globally.

A transmissible disease of the bursa of Fabricius of ducks [PDF]

Avian Pathology, 1994
Longitudinal surveys of commercial Pekin ducks from four farms with a history of poor flock performance and high mortality rate showed that there was lymphoid depletion of the bursa of Fabricius in most ducks selected from 7 days of age onward. Such lesions were not present in Pekin ducks from a farm with a history of good flock performance and low ...

Characterization of Harderian Gland‐Derived Plasma Cells in Chicken

European Journal of Immunology, Volume 56, Issue 6, June 2026.
An isolation protocol for plasma cells (PC) from the chicken Harderian gland (HG) was established, and analyses of PCs revealed a FSChigh/CD45med/sIgpos/CD57pos/CXCR4high/TACIlow phenotype. Presence of CXCL12 and BAFF around HG PCs suggests a contribution of CXCL12–CXCR4 and BAFF–TACI to PC localization and survival.

Safety of a feed additive consisting monensin sodium (Elancoban® G200) for chickens for fattening and chickens reared for laying (Elanco GmbH)

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the characterisation of the production strain and on the safety for the target species of monensin sodium (Elancoban® G200). The current application is a follow‐up of the re‐evaluation application of monensin sodium, intended for use as a ...

Optimizing Cassava Starch Residue Inclusion in Broiler Diets: Balancing Growth Performance, Liver Health and Gut Microbial Dynamics

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Moderate inclusion (20–30%) of cassava starch residue in broiler diets improved gut morphology and reduced E. coli counts with minimal adverse effects, while higher levels impaired growth and liver health. The findings highlight CSR's potential as a partial maize replacement, but caution is needed at elevated inclusion rates.

The evolutionary landscape and serotypic dynamics of avian infectious bronchitis virus from spike protein

iMetaOmics, Volume 3, Issue 1, March 2026.
This study integrates two decades of surveillance with genomic and structural analyses to decipher how spike protein glycosylation haplotypes drive avian coronavirus evolution. We uncover how specific glycosylation patterns associate with receptor‐binding affinity, shape global transmission dynamics, and correlate with clinical outcomes.
