OLIVEIRA, Alexandre Faraco de  e  OLIVEIRA FILHO, Horácio de. Microbiological species and antimicrobial resistance profile in patients with diabetic foot infections. J. vasc. bras. [online]. 2014, vol.13, n.4, pp.289-293. ISSN 1677-5449.


Diabetic foot infections are a difficult problem to solve, often requiring hospitalization and exposing patients to the risk of amputations. Identification of the most prevalent pathogens is useful for administration of antibiotic therapy, and can reduce mutilations.


To identify the microbiological profile and resistance to antimicrobial drugs in a series of patients with infected diabetic feet.

Material and methods:

an epidemiological, retrospective and descriptive study based on analysis of medical records from diabetic patients with plantar lesions who underwent surgical treatment over a 24-month period at a public hospital. Data were collected on age, sex, length of hospital stay, cultures from lesions, antibiotic therapy administered, bacterial resistance and surgeries conducted, with statistical analysis of means and standard deviations.


There were 66 admissions of diabetic patients, the majority elderly people (77%). Hospital stays ranged from 2 to 29 days, with a mean of 12.42. There were 91 surgical procedures, resulting in some kind of amputation in 65% of cases. The most common bacterial group was enterobacteria (47%), followed by staphylococci (27%). Three patients (4.5%) had multi-resistant organisms. Resistance to clindamycin was the most common at 39 admissions (59%), followed by resistance to cephalexin, seen in 24 admissions (36%).


Diabetic foot infections were most often caused by germs found in the community, in particular the enterococci. Bacterial resistance was very widespread and was most commonly associated with drugs for oral administration, in particular clindamycin and cephalexin.
