Prevalence and Molecular Characterization of Carbapenemase-Producing Multidrug-Resistant Bacteria in Diabetic Foot Ulcer Infections.

Diabetic foot ulcers (DFUs) represent severe complications in diabetic patients, often leading to chronic infections and potentially resulting in nontraumatic lower-limb amputations. The increasing incidence of multidrug-resistant (MDR) bacteria in DFUs complicates treatment strategies and worsens patient prognosis. Among these pathogens, carbapenemase-producing pathogens have emerged as particularly concerning owing to their resistance to β-lactam antibiotics, including carbapenems.

Identifying multidrug-resistant organisms in diabetic foot ulcers: a study of risk factors and antimicrobial resistance genes.

This study aims to evaluate the antibiotic susceptibility profiles of bacterial isolates from DFU patients, identify the prevalence of MDROs, and identify specific risk factors contributing to these infections to inform effective antibiotic treatment strategies. This prospective cohort study included 187 DFU patients from March 2023 to February 2024 at King Khalid Hospital, Saudi Arabia. The exclusion criteria were nondiabetic ulcers, specific infections, tumours, or recent antibiotic use.
