Genomic and Phenotypic Data on Listeria Monocytogenes from Chengdu Catering Facilities

Xueqiang Chen's study provides genomic and phenotypic data on Listeria monocytogenes isolates from 24 catering facilities in Chengdu. The dataset includes a 6.43% prevalence rate, serotype and sequence type distributions, and disinfectant tolerance gene profiles. It was last updated on May 8, 2026.

Use Cases

• Analyze disinfectant tolerance gene prevalence based on the 100% presence of Ide/mdrL and fosX genes mentioned in the description
• Compare disinfectant efficacy based on the reported MIC ranges for NaClO, QACs, and H2O2
• Identify high-risk contamination nodes in food service operations based on the reported cross-contamination pathways and hotspot locations
• Study serotype and sequence type distribution patterns based on the reported dominance of serotype 1/2a and ST101/ST121

Strengths

• Includes specific prevalence rates (6.43%) and hotspot contamination data (e.g., 25.0% in cleaned meat areas)
• Provides detailed genomic characterization, including serotype dominance (65.0% 1/2a) and gene presence (100% for key tolerance genes)
• Contains phenotypic testing results with specific MIC ranges for multiple disinfectants

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 small (197.8 KB), indicating limited scope
