Characterization of Foodborne Pathogens in Biofilms: A Four-Dimensional Structural Dynamics Approach Using HCS-CLSM

Area of Science:

• Microbiology
• Biophysics
• Microscopy

Background:

• Biofilm properties are linked to their spatial architecture, making structural data crucial for understanding biofilm behavior and control.
• Confocal laser scanning microscopy (CLSM) is a key tool for noninvasive, 3D investigation of biofilm structure and dynamics at the single-cell level.

Purpose of the Study:

• To present a high-content screening (HCS)-CLSM protocol for high-throughput analysis of biofilm four-dimensional structural dynamics.
• To enable a greater volume of structural data for meta-analysis and improved biological understanding of biofilm traits.

Main Methods:

• Utilized fully automated high-content screening (HCS) systems.
• Integrated large-scale image analysis with CLSM for biofilm structural data acquisition.
• Developed and applied a HCS-CLSM protocol for high-throughput, 4D biofilm analysis.

Main Results:

• Significantly amplified the availability of biofilm structural data through automated HCS-CLSM.
• Enabled high-throughput quantitative analysis of biofilm structural dynamics.
• Extracted quantitative variables for subsequent meta-analysis.

Conclusions:

• The HCS-CLSM protocol facilitates rapid and extensive structural analysis of biofilms.
• Meta-analysis of HCS-CLSM data will advance the biological understanding of biofilm characteristics and strategies.
• This approach holds potential for improving biofilm control strategies through enhanced structural insights.
