Biofilm Disruption Enhances Antimicrobial Therapy for Small Intestinal Bacterial Overgrowth and Intestinal Methanogen Overgrowth
PMID: 41394228Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO) often persist or recur despite antimicrobial therapy. We hypothesized that biofilms, protective microbial structures, may contribute to treatment resistance.
We evaluated whether adding a biofilm-disrupting agent to antimicrobial therapy was associated with improved outcomes in patients with SIBO or IMO.
Key Findings:
- Study type: Clinical analysis of SIBO/IMO patients
- Adding a biofilm disruptor was associated with improved treatment response
- Higher rates of breath test normalization were observed when biofilm strategies were included
Clinical Implication
These findings support the role of biofilms in persistent SIBO and IMO and inform our use of targeted biofilm-disruption strategies in selected patients.
