Introduction: Diabetic foot infections are common and serious, leading to prolonged hospitalizations and increased morbidity and mortality. Understanding the bacteriological profile of these infections is essential to improve patient management. The aim of our study is to establish the microbial flora found in these lesions.

Patients and Methods: This is a descriptive retrospective study conducted on 46 patients hospitalized in our department for diabetic foot who underwent bacteriological sampling. Data were analyzed using Python with the Pandas library.

Results: Our cohort included 46 patients with an average age of 54 years, 76% of whom were over 40 years old. Males predominated with a sex ratio of 6.6. The average delay in management was 45 days. More than half of the lesions were classified as stage B Texas University (54.3%), with 41% classified as Texas 3B. The treatment duration exceeded 6 weeks in more than 80% of cases. The infections were dominated by Gram-positive cocci (47.8%), Gram-negative bacilli (21.7%), and Enterobacteriaceae (13%). The most frequently implicated bacteria were Staphylococcus, Enterococcus faecalis, Enterobacter cloacae, Escherichia coli, followed by Pseudomonas aeruginosa, Morganella morganii, Proteus mirabilis, and Streptococcus. The absence of bacteria in some samples may be due to inadequate sampling or prior antibiotic use.

Conclusions: Diabetic foot infections are common, often managed late, and require prolonged antibiotic therapy. This study provides a detailed profile of the bacteria involved to guide antibiotic selection and improve management.
