Lawsonia Intracellularis Prevalence and Gut Microbiome Data from Pigs in Shaanxi, China

Yu Wang's dataset contains results from a 2022–2023 study investigating Lawsonia intracellularis infection in pigs from five intensive farms in Shaanxi Province, China. It includes fecal and serum sample results from 672 and 300 samples respectively, with microbial diversity analysis from 16S rRNA sequencing. The data shows an overall fecal positive rate of 15.3% and a serum seroprevalence of 14.7%.

Use Cases

• Modeling pathogen prevalence based on regional and farm-level data mentioned in the description
• Analyzing correlations between specific gut microbial taxa (e.g., Lactobacillus, Desulfovibrionaceae) and infection status as described
• Identifying microbial biomarkers for Lawsonia intracellularis infection using the random forest analysis results described

Strengths

• Includes results from 672 fecal and 300 serum samples, providing a substantive sample size
• Reports specific prevalence rates with 95% confidence intervals (15.3% fecal, 14.7% serum)
• Integrates multiple analysis methods (qPCR, ELISA, 16S rRNA sequencing, LEfSe, network analysis) as described

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Data is limited to five farms in Shaanxi Province, China, which may limit generalizability
• Dataset is very small (11.8 KB), indicating it likely contains summary results rather than raw sequence data
