[Clinical characteristics of methicillin-resistant Staphylococcus aureus in phlegm specimens].
ABSTRACT To investigate the clinical characteristics of methicillin-resistant Staphylococcus aureus (MRSA) in phlegm specimens of positive patients, so as to provide evidences for the nosocomial infection control.
We retrospectively analyzed the clinical data of 211 hospitalized patients who were MRSA-positive in their phlegm specimens in PUMC Hospital from January 2005 to October 2007.
Among the 211 patients, 196 (92.9%) had received antibiotics three months before the detection of MRSA, and 128 (60.7%) had received more than three antibiotics. Over 90% of MRSA were resistant to levofloxacin, erythromycin, clindamycin, and gentamicin, and 73.9% were resistant to rifampicin.
Improper use of antibiotics should be avoided. Vancomycin is the first choice for MRSA treatment.
