Aim: The aim of this research is to study the etiological structure and resistance to antibiotics main pathogens of surgical
Methods: A total of 943 strains isolated from hospitalized patients with surgical infection at National Scientific Medical
Research Center during 2012-2014 were included to the study. The identification of isolates and antibiotic susceptibility testing
was performed by VITEK 2 (bioMerieux) automated system.
Results: The etiological structure of microbiological landscape were performed the most frequently pathogens of
Enterobacteriacae-51.7% of the total number of isolatesincluding E. coli stood in 29.0% of cases. The next group of frequency
isolation was non-fermentative gram-negative bacilli-18.5% including detection of Pseudomonas aeruginosa was 17.8%. The most
frequently gram-positive pathogens were Staphylococus (15.1%) and Enterococcus (10.6%). The detection rate of Staphylococcus
aureus were 6.5% witch resistance to oxacillin were 9.1%. Average number of no susceptible strains to fluoroquinolones and
macrolides was 20.4%.Resistant strains of E.coli to amoxicillin/clavulanate were 28.4%, cefotaxime-32.2%, ceftazidime-28.9%,
cefepime-29.1%, ciprofloxacin-30.4%. Resistant strains of Pseudomonasaeruginosa to ceftazidime were 44.5%, cefepime-33.8%,
meropenem-34.0%, gentamicin-38.1% and ciprofloxacin-39.0%.
Conclusion: The main pathogens of surgical infection were E.coli, P.aeruginosa, S.aureus. In this study, strains of Pseudomonas
aeruginosa have the greatest resistance to antibiotics traditionally used to treat infections caused by this pathogen.
