Abstract：Objective To analyze the detection,distribution and drug resistance trend of Staphylococcus aureus in Changshu during novel coronavirus infection epidemic,so as to provide scientific basis for infection prevention and clinical treatment.Methods The data of Staphylococcus aureus and Methicillin resistant Staphylococcus aureus(MRSA)isolated from various clinical specimens in Changshu from 2019 to 2021 were analyzed retrospectively,and the relevant data were classified and counted.Results The highest proportion of Staphylococcus aureus was in wound secretion samples,followed by sputum and blood samples.Staphylococcus aureus had sensitivity rates of 100%to Vancomycin,Tigecycline,Linezolid and Quinuputin/Dafoputine,and a resistance rate of over 85%to Penicillin G.There was a decreasing trend in sensitivity to Levofloxacin and Oxacillin,while resistance to Penicillin G and Erythromycin had improved.MRSA had a resistance rate of 100%to Penicillin G,and a sensitivity of 100%to Vancomycin,Tigecycline,Linezolid and Quinuputin/Dapputine.The sensitivity to Levofloxacin decreased,but the sensitivity to Erythromycin increased.Conclusions The epidemic situation affects the detection rate and distribution characteristics of Staphylococcus aureus infection.Strengthening drug resistance monitoring and isolation measures would help to curb multi drug resistant bacteria.
