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

15.3% of fecal samples from five intensive pig farms in Shaanxi Province tested positive for Lawsonia intracellularis between 2022 and 2023. The dataset includes results from 672 fecal and 300 serum samples analyzed via qPCR and ELISA, alongside 16S rRNA sequencing data comparing infected and non-infected pigs.

Use Cases

• Modeling the association between Lawsonia intracellularis infection and specific gut microbial taxa like Lactobacillus based on the LEfSe analysis results.
• Identifying microbial biomarkers for porcine proliferative enteropathy using features like Erysipelotrichaceae_UCG.003 identified via random forest analysis.
• Analyzing regional variations in pathogen prevalence, such as the significantly lower fecal positive rate reported for Tongchuan.
• Studying co-occurrence networks within the porcine gut microbiome based on reported correlations between Desulfovibrionaceae and Lachnospiraceae.

Strengths

• Includes results from a substantial sample size of 672 fecal and 300 serum specimens.
• Provides precise prevalence statistics with confidence intervals (e.g., 15.3% fecal positive rate, 95% CI: 12.7–18.3%).
• Integrates multiple data types: pathogen detection (qPCR), serology (ELISA), and microbiome profiling (16S rRNA sequencing).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to five farms in a single Chinese province, which may affect generalizability.
