Introduction: The aim of the study was a retrospective analysis of intestinal flora for the presence of multidrug-resistant strains, isolated from patients hospitalized in clinics Oncology Center from 01.01.2010 to 30.09.2015 r.
Methods: The multi-resistant strains were isolated from stool and rectal swabs. In order to increase the potential of multiple-resistant strains, the material was plated on the appropriate substrate. Determination of resistance mechanisms performed by general recommendations.
Results: Results of this study showed among isolated multiple-resistance strains a high proportion of Enterobacteriaceae strains producing β-lactamase mainly ESBL. Klebsiella pneumoniae consist of 31.9% of isolated strains, E. coli 28.74% and Enterococcus faecium VER -21.15%.
Conclusions: It is important to determine the microbiological status of hospitalized patients because colonized gastrointestinal tract multi-resistant strains may be one of the sources of serious infections.
