Foot infections in Diabetic Patients in Spain First Author: Carolina Padrós Authors: Carolina Padrós ,Teresa Vinuesa Consol Truchero, Miquel Viñas. 1Laboratory of Microbiology and Podiatry Clinic. Campus de Bellvitge. University of Barcelona. Feixa Llarga s/n E-08907. L'Hospitalet. Barcelona. Spain. 2 Intensive Care Unit. Hospital de Bel Background. Foot infections affect 25 % of diabetic patients. These are much more difficult to treat than those produced among non-diabetics. Although many foot infections have a polymicrobial origin, Staphylococcus aureus appears to be the predominant. The antibiotic abuse among Spanish population is considered to be one of the main reasons for the high incidence of infections caused by multiresistant bacterial strains. Methods. A total of 68 diabetic patients suffering foot ulcerations were studied. Samples were obtained and cultured, and microorganisms identified and their antibiotic susceptibility determined. Results. A high frequency of resistant (occasionally multiresistant) isolates was obtained. Staphylococcus aureus was predominant in 69% of samples, whereas Pseudomonas aeruginosa was the predominant microorganism in 20 % of the samples, finally Streptococcus spp. was the most abundant microorganism in 10 % of the samples. A high degree of antimicrobial resistance was detected. Conclusions. Results indicate high incidence of multiresistant bacterial strains. The use of topical antibiotic treatments is suggested to prevent selective pressure that can favor the emergency of multiresistant strains. |
