In the recent years the primary microorganisms causing nosocomial infections has been staphyloccocus and nasal carriage is known as an important factor in the formation of these infections. In this study we investigated the nasal carriage of the staff from the different units of the Florence Nightingale Hospital and the antimicrobial susceptibilities of the isolated strains. Totaly the nose cultures of 400 staff were performed including 165 in 1998 and 235 in 1999. The nose smear samples were cultured on sheep blood agar and endo agar. The gram stain, catalase, coagulase testing, morphological and microscopic properties of the bred colonies were investigated. The identification and antimicrobial susceptibility testing of gram positive and gram negative bacteria were done in the Sceptor (Becton Dickinson) device.

In a total amount of 73 staff, 39 (9.8 %) Staphylococcus aures susceptible to meticilline (MSSA); 6 (1.5 %) meticilline resistant S.aureus (MRSA), 9 (2.3 %) Klebsiella oxytoca, 8 (2 %) Klebsiella pneumoniae, 4 (1 %) Proteus mirabilis, 3 (0.8 %) Entrerobacter aerogenes, 2 (0.5 %) Enterobacter cloacae, 1 (0.3 %) Acinetobacter baumannii, 1 (0.3 %) Citrobacter freundii were isolated. For S.aureus strains vancomycin 100 %, teicoplanin 100 % ofloxacin 89 % and for gram negative strains imipenem 100 %, siprofloxacin 90 % were found to be the most effective antimicrobials.

We think that by the periodical investigation of the nasal carriage of the hospital staff and by maintaining the necessary precautions, the nosocomial infections will decrease in a certain ratio.
