Infectious Bronchitis Virus Lineage Dynamics in Vaccinated Broiler Farms Over 2 Years

Six commercial broiler farms were monitored over 2 consecutive years to evaluate how changes in vaccination strategy affect IBV lineage dynamics. The study used a sentinel-bird model, with non-vaccinated birds sampled for IBV detection, genotyping, and serology, resulting in an overall IBV detection rate of 65%. The dataset, authored by Ariel Eduardo Vagnozzi and last updated in June 2026, supports findings on lineage distribution shifts following vaccine strategy changes.

Use Cases

• Analyzing the impact of vaccine strategy changes on viral lineage prevalence based on the comparison of two survey years.
• Modeling the tissue tropism of different IBV lineages based on the association of GI-1 with respiratory tissues and GI-16 with lymphoid tissues.
• Studying viral co-circulation and mixed infections in vaccinated flocks based on the detection of multiple lineages and elevated antibody titers.
• Evaluating the persistence of vaccine strains like GI-13 after cessation of use, as described in the study findings.

Strengths

• Data collection spans 2 consecutive years across 6 commercial farms, providing a longitudinal view.
• Overall IBV detection rate of 65% is quantified, and statistical significance (P < 0.0001) for lineage expansion is reported.
• Study design includes a sentinel-bird model for direct monitoring within vaccinated flocks.

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment.
• The dataset is very small at 54.0 KB, indicating limited scope or summary-level data.
• Geographic location of the farms is unspecified, which may limit generalizability.
