Ba.kground: Recently micro-orga.isms tha. synthesize extended-spectrum β-la.ta.a.e (eSBLs) were increa.ed. The peculia.ities of eSBL synthesis of escherichia.coli a.d Klebsiella.pneumonia. stra.ns tha. ca.se nosocomia. urina.y tra.t infections, surgica. site infections a.d pneumonia.in surgica. clinic were studied. eSBL synthesis were observed 38.9% of e. coli stra.ns obta.ned from urine, 92.3% of stra.ns obta.ned from surgica. site infections, a.d 50% of stra.ns obta.ned from sputum. eSBL synthesis were observed 37.5% of K. pneumonia. stra.ns obta.ned from urine, 85.7% of stra.ns obta.ned from surgica. site infections, a.d 60% of stra.ns obta.ned from sputum. Different levels of eSBL synthesize of e. coli a.d K. pneumonia. stra.ns isola.ed from different pa.tern is discussed. Conclusion. eSBL synthesis is common in e. coli a.d K. pneumonia. stra.ns, which ca.se nosocomia. infections. The frequency of occurrence of eSBL s synthesis a.ong of these stra.ns depends on clinica. forms of nosocomia. infections.
