Abstract
1235 strains of Staphylococci isolated in a multidisciplinary children's clinic were analyzed. The species and antibiotic resistance of Golden and coagulase-negative Staphylococci were studied. The most frequently identified species were: S. aureus-36.06%, S. epidermidis-23.05%, S. haemolyticus-19.7%, S. hominis-14.03%. Phenotype methicillinsensitive strains had 48.9% of the allocated staphylococci, while metitillinrezistentnykh S. aureus was identified in 25.6%, and coagulase-negative staphylococci methicillinresistant- 63.2 per cent. The frequency of associated resistance to aminoglycosides, fluoroquinolones, macrolides and tetracyclines have metitillinresictant strains 92,7%, 78,3%, 83,4% and 52,05% respectively, resistant Staphylococcus and coagulase-negative staphylococci were similar. The minimum number of resistant strains was found in relation to daptomycin, no strains resistant to vancomycin and linezolid were found. Antibiotic resistance of staphylococci in children's hospitals is determined by the presence of the mecA gene or sensitivity to cefoxitin and does not depend on the type of strain.
