Table 1_Genomic characterization of vancomycin-resistant Enterococcus faecium and van-carr

19 vancomycin-resistant Enterococcus faecium (VREfm) isolates were collected from a tertiary hospital in northeastern China between 2019 and 2024. Whole-genome sequencing data was analyzed to determine sequence types, plasmid groups, and the genetic context of van gene clusters. The dataset, authored by Han Yao and shared under CC-BY-4.0, provides genomic insights into the diversity of VREfm isolates and associated mobile genetic elements over a five-year period.

Use Cases

• Analyze the distribution of vanA and vanM resistance genes across different bacterial sequence types.
• Study the structural diversity of Tn1546 transposon variants and their association with plasmid backgrounds.
• Investigate the temporal shift in dominant sequence types (e.g., ST17, ST68, ST78) within a hospital setting.
• Examine plasmid fragmentation events indicated by plasmids lacking functional replicons.
• Compare plasmid groups and their shared resistance genes across different clonal lineages.

Strengths

• Data covers a 5-year sampling period (2019-2024), allowing for temporal trend analysis.
• Includes genomic analysis results for 19 distinct bacterial isolates.
• Analysis includes multiple characterization layers: sequence typing, plasmid grouping, and transposon analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (11.5 KB), indicating limited scope.
