Drug-resistance and Clinical Distribution of Staphylococcus Strains Isolated from Inpatients / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate drugresistance and clinical distribution characteristics of Staphylococcus strains isolated from inpatients.METHODS The meticillin-resistance and drug-resistance of the Staphylococcus strains isolated from the clinical specimens of the inpatients in our hospital between 2003 and 2005 were tested.RESULTS Totally 768 Staphylococcus strains were mainly isolated from sputum,blood,pus and wound secretion.The main clinical wards were from pediatrics,ICU,tumor chemotherapy departments.The age of these inpatients were mainly over 60 years old(48.7%) and less than 13 years old(33.2%).Two hundred and ninetyStaphylococcus aureus strains(37.8%)and 478 coagulase-negative Staphylococcus strains(62.2%)were included.The isolated rates of meticillin-resistant S.aureus and meticillin-resistant coagulasenegative Staphylococcus were 74.8% and 89.1%,respectively.CONCLUSIONS Infections of Staphylococcus are increased year by year among inpatients.There are high rates of meticillin-resistant strains.It is very important to monitor infections of Staphylococcus,to control the source of infections,to interrupt their spread and to protect impressionable inpatients,in order to prevent infections of Staphylococcus actively.
