Introduction. Long-lasting ulcerative defects in patients with diabetic foot syndrome (DFS) are prone to reinfection, persistence of primary and hospital-acquired infection, and the infectious process is often caused by multidrug-resistant organisms (MDRO).Aim of the study: to compare the prevalence and specific characteristics of the severe diabetic foot infection pathogens during the inpatient and outpatient stages of treatment.Materials and methods. We included 62 type 2 diabetic inpatients (group 1) with severe foot infection and 102 diabetic foot outpatients (group 2) with postoperative wounds, who had been operated on and discharged from the hospital, in to the study.Cultures were obtained after surgery interventions immediately and on 14 days of hospitalization in group 1 of patients and in group 2 of patients with clinical signs of infection. Microbe species and resistant of pathogens to antibiotic were assessed.Results and discussion. Severe infection connected with polymicrobe pathogens in both groups of patients. However, the prevalence of Gram-positive and Gram-negative bacilli was different. The most frequently isolated pathogens were Gram-positive bacteria in the wound samples of group 1 of patients with acute infection obtained after surgery interventions immediately. In the wound cultures of group 1 on 14 day of hospitalization and group 2 the prevalence of Gram-positive and Gram-negative bacilli was the same. It should be noted that there is still a high total frequency of isolation of non-fermenting Gram-negative bacilli among Gram-negative pathogens in complicated diabetic foot infection both at the inpatient and outpatient stages of treatment.Conclusion. The great finding of the study is the identification of a parallel of the same prevalence of Gram-positive and Gramnegative pathogens in a prolonged infection at the inpatient and outpatient stages of treatment. The role of Enterobacterales increased with duration of infection. The prevalence of multidrug resistant Enterobacterales makes this group of microorganisms as important as Staphylococcaceae in the complicated course of the infectious process. Polyvalent microbial spectrum of pathogens significantly reduces the effectiveness of treatment.
