Aim: This study investigated the spectrum of bacteria infecting the ulcers of individuals with diabetes at the Korle Bu Teaching Hospital in Accra, Ghana, focusing on Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA), with respect to their prevalence, factors predisposing to their infection of the ulcers, and antimicrobial resistance patterns. Methodology: This cross-sectional study was conducted at The Ulcer Clinic, Department of Surgery, Korle Bu Teaching Hospital, involving 100 diabetic foot ulcer patients. The ulcer of each study participant was swabbed and cultured bacteriologically, following standard procedures. Antimicrobial susceptibility testing was done for all S. aureus isolated, using the Kirby-Bauer method. Results: In total, 96% of the participants had their ulcers infected—32.3% (n = 31) of these had their ulcers infected with one bacterium, 47.9% (n = 46) with two bacteria, 18.8% (n = 18) with three bacteria, and 1.0% (n = 1) with four bacteria. The prevalence of S. aureus and MRSA were 19% and 6%, respectively. The distribution of the other bacteria was as follows: coagulase-negative Staphylococci (CoNS) (54%), Escherichia coli (24%), Pseudomonas spp. (19%), Citrobacter koseri and Morganella morgana (12% each), Klebsiella oxytoca (11%), Proteus vulgaris (8%), Enterococcus spp. (6%), Klebsiella pneumoniae (5%), Proteus mirabilis and Enterobacter spp. (4%), Klebsiella spp. (2%), and Streptococcus spp. (1%). The resistance rates of S. aureus decreased across penicillin (100%, n = 19), tetracycline (47.4%, n = 9), cotrimoxazole (42.1%, n = 8), cefoxitin (31.6%, n = 6), erythromycin and clindamycin (26.3% each, n = 5), norfloxacin and gentamicin (15.8% each, n = 3), rifampicin (10.5%, n = 2), linezolid (5.3%, n = 1), and fusidic acid (0.0%, n = 0). The proportion of multidrug resistance was 47.4% (n = 9). Except for foot ulcer infection with coagulase-negative Staphylococci, which was protective of S. aureus infection of the ulcers (OR = 0.029, p = 0.001, 95% CI = 0.004–0.231), no predictor of S. aureus, MRSA, or polymicrobial ulcer infection was identified. Conclusions: The prevalence of S. aureus and MRSA infection of the diabetic foot ulcers were high, but lower than those of the predominant infector, coagulase-negative Staphylococci and the next highest infecting agent, E. coli. Diabetic foot ulcers’ infection with coagulase-negative Staphylococci protected against their infection with S. aureus. The prevalence of multidrug resistance was high, highlighting the need to further intensify antimicrobial stewardship programmes.

Abstract Background and aims: Infected foot ulcer is one of the most feared complications of diabetes mellitus. Staphylococcus aureus is the most frequently isolated pathogen in diabetic foot infections. The aim of this study was to evaluate the prevalence of S. aureus strains involved in producing foot infections in diabetic patients and the antibiotic resistance pattern of these strains. Material and methods: The study included 33 S. aureus strains isolated from 55 diabetic foot ulcers. The subjects were selected from the 2465 patients with diabetes mellitus hospitalized in the Timişoara Diabetes Clinic, between 2011 and 2013. Germs’ identification relied on cultural and biochemical characteristics. Final identification and antimicrobial testing were performed using the Vitek 2 (Bio Merieux France) automatic analyzer. Results: All the 55 samples collected from diabetic foot ulcers were positive. We isolated 64 bacterial strains (some samples were positive for 2 microorganisms). The most frequently isolated germ was S. aureus, in 33 samples (51.56%). All these S. aureus strains showed resistance to benzylpenicillin, while only 33.33% were methicillin-resistant (MRSA). Conclusions: The most frequently isolated germ in the wound secretions from diabetic foot ulcers was S. aureus. The highest percentage of antimicrobial resistance was recorded to benzylpenicillin and erythromycin.
