Diabetic Foot Infection in Morocco: Microbiological Profile.
OBJECTIVE The objective of this work is to describe the microbiology of diabetic foot infections (DFIs) MATERIALS AND METHODS The authors included all samples of infected diabetic foot ulcers between January 2009 and June 2014 at the Mohammed Vth Military Teaching Hospital of Rabat, Morocco. RESULTS The researchers collected 199 samples corresponding to 157 patients. The mean age of the patients was 59 years 12 years. Of the collected samples, deep samples represented 41% and swab samples 59% Direct examination indicated anaerobic infection in 32% of the cases. There were 307 bacteria isolates from both deep and swab samples. There was no statistically significant association between the sampling method and isolate species (P 0.237) Enterobacteriaceae, Staphylococcus aureus, Streptococcus sp, nonfermenting gram negative bacilli (NFGNB) and Enterococcus sp represented 31.8% 12.6 12.3% 11.7% and 8.7% of the isolates, respectively. Methicillin resistant S. aureus represented 4.7% of S. aureus isolates. Enterobacteriaceae and NFGNB producing extended spectrum b lactamases represented 14.1% and 5.1% respectively, with isolates producing carabapenemase representing 3.8% and 38.5% Piperacillin tazobactam, imipenem, and ciprofloxacin resistance concerned 7.5% 4.7% and 25.5% respectively, of isolated Enterobacteriaceae, and 35.9% 30.7% and 35.9% of NFGNB. Low susceptibility to b lactams was found in 4.9% of Streptococcus sp isolates and 4.9% of Streptococcus sp isolates were resistant to moxifloxacin. CONCLUSION Gram negative bacilli are responsible for 43% of DFIs, and multidrug resistant GNB is a challenging issue in DFI management. The sampling method doesn't seem to impact the bacteriological profile; however, this finding must be confirmed with further study.
