Table 1_Raman signatures of Cnm-positive Streptococcus mutans: II, screening the virulence

Giuseppe Pezzotti's 2026 study presents Raman spectroscopic data for estimating the virulence of Streptococcus mutans bacteria. The dataset likely contains spectral parameters from six clinical isolates, three Cnm-positive and three Cnm-negative, with ten spectra averaged per sample. The data supports the development of spectroscopic classification criteria matching genomic analyses for bacterial virulence.

Use Cases

• Developing classification algorithms for bacterial virulence based on spectroscopic parameters mentioned in the description.
• Correlating Raman spectral features, such as protein-peptidoglycan balance, with genomic classifications of clinical isolates.
• Training models for rapid, chairside risk assessment of endocarditis and stroke linked to Cnm-positive bacteria.
• Benchmarking spectroscopic methods against traditional genomic analysis for pathogen characterization.

Strengths

• Data is derived from a statistically significant series of ten Raman spectra collected per clinical sample.
• Includes a direct comparison of six characterized clinical isolates, with three Cnm-positive and three Cnm-negative.
• Spectroscopic classifications were validated against genomic analyses, as stated in the description.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset is very small at 14.1 KB, with an unknown row count, limiting statistical power.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is based on a limited series of six isolates, which may affect generalizability.
