Resumo

Diabetic foot infections are obviously spreading in hospital and facing unique challenge of successful treatment because of wide spread of resistant bacteria to many antibiotics. The clinical use of combination of antibiotics could be one of strategies to combat these resistant bacteria. Thus, basely depends on the microbial etiology and appropriate selective to antibiotics for combination. Using manual E-test method, Minimum inhibitory concentration (MIC) was determined susceptibility to individual antibiotics. Fractional inhibitory concentration index (FICI) was used to determine synergistic effects for combined antibiotics. Gentamicin susceptibility showed 100%, 40%, 80% and 60% of E.coli, Pseudomonas.spp, Staphylococcus aureus, and Proteus spp were sensitive, respectively. Ciprofloxacine showed 90%, 60%, 30% and 80 % resistant to E.coli, Pseudomonas spp, Staphylococcus aureus, and Proteu spp, respectively. Ceftriaxone showed 50%, 50%, 10%, and 80% resistant result against E.coli, Pseudomonas.spp, Staphylococcus aureus, and Proteus spp, respectively. Fractional inhibitory concentration index provided that 20%-40% Pseudomonas strains were synergistic to (gentamicin plus ciprofloxacin) and (gentamicin plus ceftriaxone), respectively. Since 100% of E.coli were antagonism to both combination. However, 80%-90% of Staphylococcus aureus, 70%-80% of Proteus spp showed indifferent effect to (gentamicin plus ciprofloxacin) and (gentamicin plus ceftriaxone), respectively.
