Infectious bronchitis vaccine virus detection and part-S1 genetic variation following single or dual inoculation in broiler chicks. [PDF]

, 2017
An investigation was undertaken of the extent of genetic variation occurring within infectious bronchitis virus (IBV) vaccine strains following vaccination of day-old broiler chicks. Chicks were divided into seven groups, with two groups receiving single

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.

Bridging the gap: improving methodologies for future avian microbiome research

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco‐evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological ...

Bacterial Culture‐Based Analysis of the Tuatara Gut Reveals Functional Roles of the Core Genus Chryseobacterium

New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
The microorganisms living in a host's gut are important for digestion and immune response and are an important facet to understanding host ecology. For tuatara, the gut microbiome presents an opportunity to examine bacteria associated with a long‐lived and evolutionarily distinct reptile and to understand how tuatara ecology is mediated or supported by

Risk factors and likelihood of Campylobacter colonization in broiler flocks

Brazilian Journal of Poultry Science, 2007
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined.

Chicken Origin Tribasic H9N2 Avian Influenza Virus Induces Potent Early Antiviral Response With Low Pathogenicity in Japanese Quails

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
This study gives valuable insights into host–pathogen interaction and confirms that the circulating tribasic H9N2 virus remains phenotypically low pathogenic in Japanese quails in Bangladesh but cause long‐term impairment of important productivity parameters (weight gain, laying rates).
