Sažetak Study goal: As a part of annual resistance surveillance coordinated by Croatian academy of medical sciences, study on resistance of Staphylococcus aureus isolates to antimicrobial drugs was performed together with analysis of origin of strains and number of strains isolated from different body sites. Methods: During last three months of 2004 (October till December), succesive Staphylococcus aureus isolates were collected from 27 laboratories in 20 Croatian cities. Strains were sent to Department of clinical and molecular microbiology in CHC Zagreb with accompanying form containing patient data, diagnosis, hospital stay and other epidemiological data. During that period, 1815 isolates were collected and sensitivity testing to 18 antimicrobial drugs was performed according to CLSI guidelines and interpretation standards, and interpretation of BSAC for mupirocin and fucidic acid. Results and conclusion: Collection of S. aureus isolates presents majority of Croatian isolates in study period, therefore susceptibility results are representative of Croatia. 48% of SA is isolated from nasal/nasopharyngeal swabs, wound swab percentage is 27%, sputum is and lower respiratory tract specimen is respresented with 9% of isolates, percentage of blood and CSF isolates is 4%. MRSA prevalence varies from 0% to 47.6%. |
