Analysis of Resistance of MRSA to Antibiotics

Objective MRSA hospital to commonly used antibiotic resistance testing,analysis of resistance of MRSA,the infection risk factors and treatment strategies.Methods Continuous monitoring of 2005—2009 in our hospital 136 cases of drug resistance in MRSA,combined with the detection of drug resistance genes,were statistically analyzed.Results The four types of penicillin resistance rate of MRSA was detected were 100%,oxacillin,gentamicin,ciprofloxacin and erythromycin resistance is very high,tetracyclines 90%,cefazolin was 79.4%,penicillin 100%,gentamicin 88.2%,ciprofloxacin 86.8%,erythromycin 95.6%.Tips for the multi-drug resistant hospital MRSA strains to β-lactams,erythromycin,gentamicin,and ciprofloxacin were resistant,and found seven cases of vancomycin-resistant MRSA.Conclusion Methicillin or oxacillin-resistant Staphylococcus aureus(MRSA) is a common nosocomial infection caused by bacteria,multiple drug resistant.In recent years an increasing number of vancomycin-resistant Staphylococcus aureus(VRSA).In this paper,the drug resistance of MRSA and resistant strains of genetic testing in order to guide the clinical development of therapeutic strategy.
