House Finch Mycoplasma Gallisepticum Infection Data from Aviary Experiments

Anna Perez-Umphrey's dataset contains experimental data on heterogeneity in house finch susceptibility to the bacterial pathogen Mycoplasma gallisepticum. Data were collected over two months from six aviary flocks, each composed of birds with either low prior exposure or naive status, following the introduction of inoculated index birds. The dataset includes longitudinal measurements of pathogen loads and pathology for individual birds.

Use Cases

• Modeling epidemic spread based on host exposure history and flock composition described in the experiment.
• Analyzing longitudinal pathogen load trajectories for individual birds over the two-month study.
• Investigating the relationship between prior pathogen exposure and disease severity outcomes.
• Comparing transmission dynamics in flocks with naive versus pre-exposed bird populations.

Strengths

• Data includes longitudinal measurements of pathogen load and pathology collected over two months.
• Experimental design controls for prior exposure history across six distinct aviary flocks.
• Dataset is shared under a permissive CC0 1.0 Public Domain Dedication license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
