Microbial bellwether: Community-scale metabolic modeling to predict infection

Area of Science:

• Microbiology
• Systems Biology
• Computational Biology

Background:

• Microbial communities are shaped by complex interactions between commensals and pathogens.
• Clostridioides difficile is a significant public-health threat associated with infections.
• Understanding these interactions is crucial for developing effective interventions.

Purpose of the Study:
