Inroduction: Diabetes mellitus comprises a group of common metabolic disorders that share the phenotype of hyperglycemia. Diabetics exhibit a great frequency and severity of infection. A diabetic with foot complication spends 32.3% of the total income compared to 9.3% by the diabetic without foot complication

Materials & Methods:  The sample taken was pus and exudates from the base of the ulcer after cleaning the necrotic tissue with a saline gauge. Direct Microscopy, Culture, Biochemical reactions & antibiotic sensitivity,

Results: The male to female ratio was 2.03 in our study, The ulcers occurred over a wide range of age from 16 years to 78 years with a mean age of 47 years.64 out of 100 cases were between the ages of 45-65 years. There was only one case below 25 years of age and 3 cases above 75 years, Monomicrobial infections are more in grades–I &II and polymicrobial infections are more in grades– III & IV. 

Conclusion: The present study was conducted to know the bacteriology and antibiogram of diabetic foot infections in and aroundMangode, Palakkaddistrict Pseudomonas aeruginosa was the most common organism isolated and constitutes 32.43% of the total isolates Out of the 15 Pseudomonal isolates that were subjected to Screening of Amp – C β lactomase by diantagonism test only 4 isolates showed blunting of Cefotaxime zone of inhibition adjacent and to Cefoxitin and were considered screen positive
