ABSTRACT
OBJECTIVE To investigate the significance of CNS in clinical infections.METHODS A total of 114 CNS strains isolated from our hospital were identified by conventional procedures and the icaD gene was amplified by PCR.RESULTS Of all CNS strains,the highest isolated rate was S.epidermidis(41.2%).CNS isolated from deep venous catheters,wound secretions and blood had a higher rate of carrying ica operon,accounted for 44.4%,42.1% and 36.8%,respectively,whereas 24.0% in respiratory secretions and 14.1% in urine.Among the ica operon positive CNS strains,the percentages of S.epidermidis and S.haemolyticus were 42.6% and 19.0%.CONCLUSIONS There is a wide range of CNS species carrying ica operon,especially in S.epidermidis.CNS isolated from different specimens might have different significances.It should be cautious to assess the results of isolated CNS from respiratory and urine specimens.The CNS isolates from blood specimens might be contaminated.The PCR method for the ica operon is simple and easy.
