Drug-Resistance of Staphylococcus in Nosocomial Infection / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study drug-resistance status in nosocomial infection with Staphylococcus in the local region,and take effective measures to control the nosocomial infection.METHODS Totally 129 strains of Staphylococcus were clinically isolated from various specimens from Jan 2006 to Dec 2008.The strain identification,detection of meticillin-resistant Staphylococcus(MRS) and K-B disk diffusion test were performed.The data were analyzed statistically.RESULTS Among all 129 strains consisting of 6 species of Staphylococcus,the isolating rate of S.aureus predominated with 39.5%.Among them,meticillin-resistant S.aureus(MRSA) accounted for 29.4%.Among all coagulase-negative Staphyloccocus(CNS),meticillin-resistant coagulase-negative Staphylococcus(MRCNS) accounted for 32.1%.Meticillin-susceptible S.aureus(MSSA) showed significantly lower drug-resistance than MRS.CONCLUSIONS Nosocomial infection status caused by MRS is serious in the grass-roots hospitals.Effective measures should be taken to control it.
