Avibacterium Paragallinarum Pathogenicity and Protection Study Data

A study investigating novel non-pathogenic Avibacterium paragallinarum isolates from U.S. layer flocks. The dataset includes results from a two-phase experiment on 26-week-old laying hens, authored by Mostafa M.S. Shelkamy and last updated in May 2026. It contains clinical, gross, and histopathological lesion scores comparing non-pathogenic and pathogenic isolates.

Use Cases

• Assessing bacterial pathogenicity based on clinical and histopathological lesion scores described in the study.
• Evaluating vaccine protection potential based on challenge experiments with serovar C1 isolates.
• Supporting differential diagnosis in poultry flocks by studying the prevalence of non-pathogenic isolates.

Strengths

• Experimental design includes seven test groups and positive/negative controls, as described.
• Data is associated with a specific study investigating isolates from five sites across four U.S. states.
• Files are available under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 7.4 MB, which may limit the scope of analysis.
