Lawsonia Intracellularis Prevalence and Gut Microbiome Data from Shaanxi Pig Farms

Yu Wang's dataset contains results from a 2022-2023 epidemiological study of Lawsonia intracellularis infection in pigs from Shaanxi Province, China. It includes fecal and serum sample test results from 672 fecal and 300 serum samples collected across five intensive pig farms. The data likely contains prevalence rates, pathogen loads, and associated gut microbiome diversity metrics from 16S rRNA sequencing.

Use Cases

• Modeling pathogen prevalence based on farm location and pig age group mentioned in the results.
• Training classifiers to predict infection status based on microbial biomarker families like Erysipelotrichaceae_UCG.003 identified via random forest.
• Analyzing correlations between specific bacterial taxa (e.g., Lactobacillus, Desulfovibrionaceae) and Lawsonia intracellularis infection status.
• Comparing microbial community diversity and richness between infected and non-infected groups as described.

Strengths

• Includes specific prevalence figures: 15.3% fecal positive rate (95% CI: 12.7–18.3%) and 14.7% serum seroprevalence.
• Sample size is explicitly stated: 672 fecal samples and 300 serum samples collected.
• Temporal and geographic scope is clear: data collected from five farms in Shaanxi Province during 2022–2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 10.6 KB, indicating limited scope.
