Abstract:
Objective To analyze antimicrobial resistance of hospital-associated methicillin-resistant Staphylococ-cusaureus(HA-MRSA)and community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA),and provide reference for clinical treatment and rational antimicrobial use. Methods From May 2013 to June 2014, Staphylococcus aureus in a hospital were collected and analyzed,strains were identified and performed antimicrobial susceptibility testing by using VITEK 2 Compact system,diagnosis of HA-MRSA and CA-MRSA were confirmed in combined with clinical symptoms.Results A total of 84 MRSA isolates were isolated (61 were HA-MRSA strains,23 were CA-MRSA).Resistant rates of HA-MRSA and CA-MRSA to penicillin G and oxacillin were both 100.00% ;to ampicillin/sulbactam was 100.00% and 95.65% respectively;to compound sulfamethoxazole was 39.34% and 34.78% respectively. Antimicrobial resistant rates of HA-MRSA to gentamicin,tetracycline,erythro-mycin,clindamycin,levofloxacin,ciprofloxacin,moxifloxacin,nitrofurantoin,and rifampicin were all higher than CA-MRSA,the difference were significant(all P<0.001).Conclusion Antimicrobial resistance of HA-MRSA and CA-MRSA are all serious,monitor should be intensified,antimicrobial use should be chosen according to antimicro-bial susceptibility testing result.
