Drug resistance of Staphylococcus aureus strains isolated from different sources

Objective To analyse antibiotic resistance of Staphylococcus aureus strains from patients and environment.Methods The antibiotic resistance of 85 Staphylococcus aureus strains from the patients and environment was determined by using VITEK 2 compact Automatic Chemistry Analyzer.Results The antibiotic drug resistant rate of 85 Staphylococcus aureus strains was 38.4%.All strains were resistant to oxacillin and penicillin.All strains were sensitive to quinupristin/dalpopristin and furan.The drug resistant rate to 15 antibiotics showed no significant different between strains from patients and environment.But the strains from patients had the higher resistant rate to 7 antibiotics than strains from environment.The detection rate of methicillin-resistant Staphylococcus aureus(MRSA)were 14.1%(12/85).All MRSA strains were isolated from patients.Conclusions MRSA mainly from patients showed multiple resistance to antibiotics than that isolated from environment.The drug resistance of the strains from environment was higher than that from patients.
