Abstract:
Objective To retrospectively analyze the distribution and drug resistance of pathogenic bacteria in urinary tract infection in Xiangyang Central Hospital from 2017-2019, so as to provide a basis for clinical treatment of urinary tract infection and rational use of antibiotics. Methods The pathogenic bacteria isolated from clinical urine culture in Xiangyang Central Hospital from January 2017 to December 2019 were collected, and BD PhoenixTM 100 was used for the identification of pathogens and antimicrobial sensitivity test. The WHONET 5.6 and GraphPad Prism 5.0 software were used for data analysis. Results A total of 3 056 strains of pathogens were isolated from 15 672 urine specimens (19.50%). Gram-negative bacteria accounted for 77.95%, of which E. coli was the most common (52.45%). Gram-positive bacteria accounted for 12.63%, including E. faecalis (4.80%) and E. faecium (4.80%). Fungi accounted for 9.50%. The clinical departments with the highest rates of urinary culture submission and positive detection were Urology (26.20%) and Endocrinology (41.90%), respectively. E. coli and K. pneumoniae had high resistance rates to piperacillin, compound trimethoprim, cefuroxime, ceftriaxone and cefazolin, all exceeding 50.00%, while P. aeruginosa was relatively sensitive to various antibiotics. The resistance rates of these three gram-negative bacteria to carbapenem antibiotics increased year by year. The isolated gram-positive cocci were mainly enterococcus faecalis and enterococcus faecalis. They were highly sensitive to linazolamide, vancomycin and teicoplanin, but the resistance rates to other types of antibiotics were quite different. The average detection rates of ESBLs-producing E. coli and K. pneumoniae were 52.90% and 59.00%, respectively. Conclusion The pathogens of urinary tract infections in Xiangyang Central Hospital from 2017 to 2019 are mainly gram-negative bacteria, and the resistance rate to carbapenem drugs is increasing year by year. The ESBLs-producing strains of E. coli and K. pneumoniae are highon should be strengthened in patients with high DOB value and smoking.
