Data Sheet 1_Clindamycin susceptibility and virulence characterization of Listeria monocyt

62 Listeria monocytogenes strains isolated from meat and meat-processing environments were analyzed for clindamycin susceptibility and virulence. The dataset includes phenotypic resistance data from disk diffusion and MIC tests, genotypic data for resistance and virulence genes from whole-genome sequencing, and strain classification by clonal complex. It was authored by Aida Pérez-Baltar and last updated on 2026-05-21.

Use Cases

• Correlating phenotypic antibiotic susceptibility with specific resistance gene mutations based on MIC and disk diffusion results.
• Identifying hypovirulent strains based on the presence of truncated or impaired virulence genes like prfA, inlA, and actA.
• Comparing genomic profiles of Listeria monocytogenes strains across different clonal complexes (CCs) such as CC31 and CC155.
• Investigating the co-occurrence of intrinsic antibiotic resistance genes (fosX, norB, mprF, sul) with acquired resistance mechanisms like vgaG.

Strengths

• Includes 62 distinct bacterial strains, providing a basis for comparative analysis.
• Integrates multiple data types: phenotypic susceptibility (MIC, disk diffusion), genotypic resistance/virulence markers, and whole-genome sequencing results.
• Characterizes strains by clonal complex, enabling phylogenetic context for findings.

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 small (583.1 KB), indicating a limited scope of analysis.

Collection Method

Strains were isolated from meat and meat-processing environments, with susceptibility characterized by disk diffusion, MIC determination, and detection of resistance-associated genes. Whole-genome sequencing was performed.
