Abstract:
OBJECTIVE To investigate the prevalence of nasal colonization among health care workers(HCWs).METHODS Nasal swabs from 93 ICU workers and 98 other clinical workers were cultured and isolated and the tests of antibiotic susceptibility were performed by using paper diffusion method.RESULTS In total,214 isolates of 8 species from 191 health care workers were recovered,of which 187 isolates were coagulase-negative Staphylococcus(CNS)(the carriage rate of 93.71%) and 8 isolates were Staphylococcus aureus(the carriage rate of 4.19%).While the total Gram-negative bacteria carriage rate was 14.14%(27 isolates).The most frequent CNS species were S.epidermidis and S.haemolyticus.The antibiotic susceptibility profiles of S.aureus and CNS differed sharply: all 8 S.aureus strains were resistant to penicillin but were fully susceptible to oxacillin,in contrast,most of CNS were resistant to both penicillin and oxacillin.The carriage rate of CNS(60.2%)and Gram-negative bacteria(26.9%)in HCWs of ICU were higher than other HCWs(P
