This study introduces an AI-powered method using light and Raman scattering to rapidly detect drug-resistant bacteria like methicillin-resistant Staphylococcus aureus (MRSA). The multimodal approach achieved high accuracy, outperforming single-signal methods.
Area of Science:
- Biotechnology
- Medical Diagnostics
- Artificial Intelligence
Background:
- Antibiotic resistance is a growing global health threat, necessitating rapid diagnostic tools.
- Distinguishing between methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) is crucial for effective treatment.
Purpose of the Study:
- To develop and evaluate a rapid, accurate method for identifying drug-resistant bacteria, specifically MRSA.
- To compare the performance of single-modal (MDLS or Raman) and multimodal AI-driven detection models.
Main Methods:
- A microfluidic platform integrated with optical fibers was used to collect Multi-angle Dynamic Light Scattering (MDLS) and Raman scattering signals from bacteria.
- Three artificial intelligence models were developed: ResistNet (MDLS), SERB-CNN (Raman), and BiFusionPathoNet (multimodal fusion).
Main Results:
- ResistNet achieved 83.8% accuracy on MDLS data.
- SERB-CNN attained 91.84% accuracy on public Raman data and 93.5% on custom data.
- BiFusionPathoNet, the multimodal model, reached a superior accuracy of 96.8%, significantly outperforming single-modal approaches.
Conclusions:
- The multimodal strategy combining MDLS and Raman scattering signals with AI is highly effective for rapid and accurate detection of drug-resistant bacteria.
- This approach offers a promising solution for timely diagnosis and management of infections caused by resistant pathogens like MRSA.
