MICROBIOLOGICAL PROFILE OF DIABETIC FEET INFECTED IN A PUBLIC
HOSPITAL OF SALVADOR - BAHIA. Diabetic foot is one of the complications of greater
impact in the carriers’ life of Diabetes Mellitus. Ulcerations in the feet are predisposing
factors to infections, and have a great association with lower extremity amputations.
Identifying microbial agents and using an appropriate antibiotic therapy are essential for
therapeutic success. Objective: To identify the sociodemographic profile and the infectious
agents present in Diabetic Foot Infections in a Public Hospital of Bahia, in the years 2014 and
2015. Methods: A descriptive cross-sectional, about the microbiological profile of diabetic
feet infected from a hospital. Data were collected from records of bacterial cultures, following
pre-established inclusion and exclusion criteria. Sociodemographic and specific variables
were analyzed. Results: Of the 61 patients analyzed, 34 were male and 27 female, with an
average age of 67.8 years. Eighty-six cultures were cultured, of which 57 were derived from
tendon fragments, and 29 from bone fragments. A total of 105 bacteria from 24 different
species was isolated, 72% Gram-negative and 28% Gram-positive. The vast majority (79%)
of the cultures had a monomicrobial character. The bacterium Pseudomonas aeruginosa was
the most prevalent, being present in 20% of the data collected, followed by Enterococcus
faecalis (13%) and Klebsiella pneumoniae (12%). Discussion: National and international
studies show differences in the microbiological profile of the diabetic foot, possibly due to the
different methodologies, severity of cases and patient follow-up. Conclusions: Infections
were more prevalent in the elderly between 60-70 years old. Gram-negative bacteria prevailed
in the cultures, with Pseudomonas aeruginosa being the most frequent. It was not possible to
evaluate the role of anaerobic bacteria in diabetic foot infections.
