Abstract: Objective To evaluate the features of bacterial spectrum and drug resistance in diabetic ulcer.Methods Excretion specimen of diabetic ulcer from 130 patients admitted into our hospital from Mar.2010 to Sep.2011 were collected for bacterial culture and drug sensitivity test.28 antibiotics were chosen from 35commonly used antibiotics to test antibiotic sensitivity to decide whether the antibiotic was sensitive (S),intermediate sensitive (I),or resistant (R).Results 19 strains were isolated from 130 cases.Staphylococcus aureus with 14.62 ％ (19 cases)rated the first,followed by escherichia coli with 13.85％ (18 cases),proteus mirabilis with 13.08％ (17 cases),staphylococcus epidermidis with 12.31％ (16 cases),enterococcus faecalis with 12.31％ (16 cases),acinetobacter baumannii with 10.77％ (14 cases).Antibiotics with high sensitivity to Gram-positive bacteria were tigecycline and vancomycin while with high sensitivity to Gram-negative bacteria were imipenem and amikacin.Conclusions Bacteria of diabetic ulcer are commonly resistant to antibiotics.It is of great importance for clinical rational drug use to know the distribution and resistance of commonly encountered bacteria.
