ABSTRACT
Objective@#To retrospectively analyze the drug resistant characteristics and distribution of multi-drug resistant bacteria infection in State Second General Hospital.@*Methods@#Total 772 cases treated in our hospital from January 2017 to September 2019 were selected as subjects. The automatic microorganism analyzer VITEC-2 and manual method were used for bacterial identification; Kirby-Bauer disk diffusion method was used for susceptibility test; WHONET 5.6.2019 software and EXCEL 2013 were used to analyze the distribution and drug sensitivity of isolated bacteria.@*Results@#Among the 772 strains of multi drug resistant bacteria, the proportion of Gram-negative bacteria was 84.9%, and the proportion of Gram-positive bacteria was 15,1%; fluconazole resistant candida accounted for 3.2%. Multi -drug resistant bacteria mostly distributed in sputum, accounting for 23.5%; 50.5% multi-drug resistant strains were from intensive care unit. </br> Resistant rates of Escherichia Coli ESBL, Klebsiella ESBL and Enterobacter spp to cephalosporins and penicillin were 100%. Resistant rates of staphylococcus aureus to antibacterial agents; cephalosporins and penicillin were 100%.@*Conclusion@#Gram-negative bacteria were the main multi-drug resistant bacteria of our study in our hospital, mainly distributing in Intensive care unit patients. They are highly resistant to most antibacterial agents, which provides a theoretical basis for the prevention and control of multi-drug resistant bacteria infection in hospital.
