Phenotypic and Genotypic Characterization of ESBL- andCarbapenemase-producing Escherichia coli Isolates in Irritable BowelSyndrome (IBS) Patients

Key Points

• ESBL- and carbapenemase-producing E. coli may adversely impact patient outcomes, suggesting the necessity for immediate attention.
• Notably high levels of antibiotic resistance were identified in E. coli isolates from the IBS cohort, emphasizing the need for careful monitoring.
• Observational analysis highlights biofilm-forming capabilities of drug-resistant E. coli strains, complicating treatment efforts in IBS patients.
• The findings underscore the importance of targeted interventions in antibiotic stewardship to manage E. coli infections effectively.
