RESUMEN
Objective To investigate the distribution and drug resistance of common bacteria isolated from geriatric hospital for 2014 -2016 years,and to provide basis for the use of infection in elderly patients. Methods Bacterial identification and drug sensitivity test of isolates from January 2014 to December 2016 were performed by Microscan WalkAway 96 automatic microorganism analyzer.The drug resistance was ana-lyzed by Whonet5.6 software.Results In 2014-2016 a total of 2 133 strains of pathogens were isolated,in-cluding 1 668 strains of gram negative bacteria,accounting for 78.2%;318 strains of gram positive bacteria ac-counted for 14.9%;leather were the top 5 bacteria were Gram-negative bacteria,522 strains of Escherichia co-li,accounting for 24.5%,407 strains of Klebsiella pneumoniae,accounting for 19.1%,244 Pseudomonas aeruginosa,Proteus strains accounted for 11.4%,163 strains of proteus,accouuting for 7.6%;141 strains of Acinetobacter baumannii,accounting for 6.6%.No resistance to vancomycin,linezolid and daptomycin in Staphylococcus and Enterococcus,were not detected in carbapenem resistant Escherichia coli,Klebsiella pneu-moniae,Proteus drug.The detection rates of ESBLs producing Escherichia coli and Klebsiella pneumoniae were 26.7% and 13.6%,respectively.The detection rates of ESBLs producing Escherichia coli and Klebsiella pneu-moniae were 26.7% and 13.6%,respectively.The resistance rates of Pseudomonas aeruginosa and Acineto-bacter Bauman to imipenem w ere 8.6% and 32.6%,respectively.Conclusion T he bacterial resistance rate level is not high,the carbapenem resistant Enterobacteriaceae and non fermentive bacteria should be paid at-tention to,and the monitoring of bacterial multi drug resistant bacteria in the management and prevention of nosocomial spread and the restriction of the use of antibacterial drugs should be strengthened.We should refer to the drug resistance monitoring data of elderly population and select rational antibiotics according to the sen-sitivity test results.
