Abstract
Background. To carry out adequate antibacterial therapy directed against pathogenic microflora in patients with surgical infection it is necessary to take into account indicators of antibiotic resistance of leading etiological agents. The aim of the work is to study the spectrum and current dynamics of changes in antibiotic resistance of purulent pathogens in soft tissues of surgical patients. Material and methods. An analysis of the results of antibiotic resistance of the seeded leading microflora in patients with purulent processes of soft tissues was made. Results. Isolates of Staphylococcus aureus from surgical patients are characterized by high resistance to all β-lactam antibiotics, the combination drug trimethoprim-sulfamethoxazole, and macrolides. The resistance of Klebsiella pneumoniae and Proteus mirabilis to all studied β-lactam antibiotics, as well as fluoroquinolones, aminoglycosides, tetracyclines, nitrofurans, and chloramphenicol ranges from 37 to 100%. Escherichia coli resistance to β-lactams, fluoroquinolones, carbapenems, and aminoglycosides reaches 50-73%. A high level of antibacterial resistance is also characteristic of other bacteria most often cultured in surgical patients. Conclusions. The most frequently cultured strains of both gram-positive and gram-negative groups of microorganisms from surgical patients are characterized by a high level of antibacterial resistance, reaching 100%. Currently, cases of polyantibiotic resistance and resistance even to reserve antibiotics are not uncommon. All this dictates the need to search for new classes of substances that have an antimicrobial effect, and metal nanoparticles may be one of them.
