ABSTRACT
Microbiological monitoring of intrahospital infections in obstetric and surgical institutions revealed the role of Klebsiella pneumoniae in the etiology of purulent septic diseases in various groups of the patients. The level and spectra of resistance in the pathogens were fixed with respect to 17 drugs. It was shown that the clinical polyresistant strains of K. pneumoniae including those resistant to at least 5 antibiotics were more frequent in the patients of the surgical departments than in the newborns and puerpera. The isolates of K. pneumoniae responsible for the intrahospital complications in the surgical patients as compared to those in the newborns and puerpera were mainly resistant to ampicillin, carbenicillin, cephalothin, gentamicin and tobramycin.
