У 102 штаммов уропатогенных E. coli (УПЭК), выделенных из мочи пациентов с инфекциями мочевыводящих путей, изучена чувствительность/устойчивость к 25 различным антибактериальным препаратам. Исследования проводили с использованием диско-диффузионного метода. Методом двойных дисков оценена продукция бета-лактамаз расширенного спектра. Продукцию карбапенемаз определяли с использованием CIM-теста. Методом ПЦР определяли принадлежность к филогенетическим группам и подгруппам, О‑серогруппам, а также частоту встречаемости генов mcr‑1, mcr‑2, mcr‑3, mcr‑4, mcr‑5, кодирующих белки, опосредующих развитие резистентности к колистину.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Установлено, что все штаммы уропатогенных E. coli в той или иной мере обладают резистентностью к антибактериальным препаратам. У всех изученных 102 штаммов выявлена резистентность к 23 антибактериальным препаратам из 8 функциональных групп. Резистентность штаммов уропатогенных E. coli в зависимости от принадлежности к филогенетическим группам и подгруппам, О‑серогруппам имела определенные отличия. Штаммы уропатогенных E. coli, обладающие высокой резистентностью (до 100,0 %), принадлежали к филогенетической подгруппе B23, основными представителями которой являются культуры наиболее часто встречающейся О25‑серогруппы. Фенотипически подтверждена продукция бета-лактамаз расширенного спектра для 69 (67,6 %) штаммов. Карбапенемазопродуцирующие культуры в исследовании не выявлены. У 3 штаммов (2,9 %) УПЭК выявлены гены mcr‑1 и mcr‑2, кодирующие резистентность к колистину.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to study the profile of antibiotic resistance of uropathogenic Escherichia coli strains isolated from patients with urinary tract infections in the urological inpatient facility of the clinical hospital in the Saratov city, depending on appurtenance to phylogenetic groups and subgroups, as well as O-serogroups.</p><sec><title>Materials and methods</title><p>Materials and methods. We assessed sensitivity/resistance to 25 different antibacterial drugs in 102 strains of uropathogenic E. coli. The studies were carried out using the disk diffusion method. The production of extended spectrum beta-lactamases was evaluated by the double disk method. Carbapenemase output was determined using the CIM test. The PCR method was applied to determine appurtenance to phylogenetic groups and subgroups, O-serogroups, as well as the frequency of occurrence of the mcr‑1, mcr‑2, mcr‑3, mcr‑4, mcr‑5 genes encoding the proteins that mediate the development of resistance to colistin.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. It has been established that all strains of uropathogenic E. coli are more or less resistant to antibacterial drugs. All studied 102 strains showed resistance to 23 antibacterial drugs from 8 functional groups. The resistance of uropathogenic E. coli had certain differences depending on belonging to phylogenetic groups and subgroups, O-serogroups. Strains of uropathogenic E. coli with high resistance (up to 100 %) belonged to the B23 phylogenetic group, the main representatives of which are cultures of the most common O-25 serogroup. The production of extended-spectrum beta-lactamases has been phenotypically confirmed for 69 (67.6 %) strains. No carbapenemaseproducing cultures were found in the study. The mcr‑1 and mcr‑2 genes encoding resistance to colistin have been identified in 3 uropathogenic E. coli strains (2.9 %).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>уропатогенные Escherichia coli</kwd><kwd>инфекции мочевыводящих путей</kwd><kwd>антибиотикорезистентность</kwd><kwd>О серогруппы</kwd><kwd>филогенетическая характеристика</kwd><kwd>бета-лактамазы расширенного действия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>uropathogenic Escherichia coli</kwd><kwd>urinary tract infections</kwd><kwd>antibiotic resistance</kwd><kwd>O-serogroups</kwd><kwd>phylogenetic characteristics</kwd><kwd>extended-spectrum beta-lactamases</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Слукин П.В., Асташкин Е.И., Асланян Е.М., Ершова М.Г., Полетаева Е.Д., Светоч Э.А., Шепелин А.П., Фурсова Н.К.
