Abstract:
OBJECTIVE To study the distribution and drug resistance of coagulase negative Staphylococcus(CNS)that leads to nosocomial infection.METHODS Nosocomial CNS was identified and then drug resistance test was performed by K-B method.Nitrocefin method and the Congo red method were utilized to detect ?-lactamase and the slime,respectively.RESULTS Of all 162 CNS strains isolated,there were 102 strains of MRCNS and 60 strains of MSCNS including 83 S.epidermidis strains,accounting for 51.2%.Among all the MRCNS and MSCNS strains above,the positive rates of the ?-lactamase were 100.0% and 5.0%,respectively,and the positive rates of the slime were 17.6% and 1.7%,respectively.The resistance rates of MRCNS to 12 types of antibiotics were higher than those of MSCNS(P
