Resumen

Objective: To determine the microbiology of diabetic foot through biopsy cultures. Methods: Patients with diabetic foot and clinical signs of infection were recruited consecutively. Cultures were processed for aerobic organisms after homogenization. For cases with multiple isolates, only the two predominant organisms were identified. The bacterial identification was carried out by biochemical procedures. The sensitivity to antibiotics was performed by diffusion method in agar plate. Results: A total of 91 biopsies were studied, 47 from men (52%). There were 102 isolates, 68 being Gram-negative bacilli (67%), with predominance of Escherichia coli (21%). A total of 28 Gram-positive cocci were isolated (28%) and 6 yeasts (6%). Twenty-four of the 68 Gram-negative bacilli were resistant to ciprofloxacin (35%). A total of 55 Enterobacteriaceae were isolated, 4 (7%) of them were extended-spectrum beta-lactamases (ESBL) producers. There were 8 Staphylococcus aureus isolates, 3 of them (38%) were methicillin-resistant. Conclusions: In comparison with reports from industrialized countries, we found a higher proportion of Gram-negative and resistant organisms in our population.
