Foot infections resulting from biofilm producers and multi-drug resistant organisms is one of the most important complications of diabetes mellitus, as it can impede the wound healing process. This study was carried out in order to determine the antibiotic resistance pattern and the biofilm production in diabetic foot ulcers isolates. Clinical samples were collected from patients suffering from diabetic foot ulcers by using sterile swabs. Antibiotic susceptibility test was done using disk diffusion method on Mueller Hinton Agar. Biofilm formation was assessed by Crystal Violet Staining Method. Staphylococcus aureus isolates were resistant to ofloxacin (83.3%), ciprofloxacin (75.0%), trimethoprim-sulphamethoxazole (75.0%), and gentamicin (58.8%) but very sensitive to oxacillin (100.0%) and vancomycin (91.7%). Pseudomonas aeruginosa isolates showed resistance to the commonly used antibiotics such as ofloxacin, cefotaxime, ampicillin (81.8%), ceftazidime and imipenem (72.7%). The majority of bacteria studied were biofilm producers. This study showed that bacteria isolated from diabetic foot ulcers were biofilm producers and presented resistance to commonly used antibiotics. Knowledge on antibiotic sensitivity pattern and biofilm phenotype of the isolates will be helpful in determining the drugs for the treatment of diabetic ulcers.
