2013—2016年胆道感染病原菌分布及耐药性分析
Distribution and Drug Resistance of Pathogenic Bacteria in Patients of Biliary Tract Infection from 2013 to 2016
摘要
Abstract
Objective To investigate the distribution and antibiotic resistance of pathogenic bacteria from the patients of biliary tract infection in Tianjin Nankai Hospital from 2013 to 2016 and provide the reference for clinical treatment. Methods The identification and the susceptibility test of the isolated bacteria were per-formed by the automatic VITEK-2 compact system,and the data was collected and analyzed using WHONET 5.6 software. Results The positive rate of bile culture was 55.53%(2631/4738). A total of 4539 bacterial strains were isolated,including 2815 strains (62.02%) of Gram-negative bacilli,1675(36.90%) strains of Gram-positive cocci and 49(1.08%) strains of fungus. The top six bacteria were Escherichia coli (26.06%), Klebsiella pneumonia (11.87%),Enterococcus faecium (10.58%),Enterococcus faecalis (10.22%),Pseudomonas aeruginosa (4.30%) and Enterobacter cloacae(3.90%).Those of Escherichia coli and Klebsiella pneumonia pro-ducing ESBLs were 54.27% and 31.54% respectively. About the two kinds,the rates of resistance to carbapen-ems were 0.76% and 0.93%. About Pseudomonas aeruginosa and Acinetobacter baumannii,the rates of resis-tance to carbapenem were 38.46% and 28.97% respectively,about Enterococcus faecium,the rate of resistance to vancomycin was 0.63%.The detection rates of MRSA and MRCNS were 56.04% and 76.79%. Conclusion The most common pathogens in biliary tract infection were intestinal,the species of resistant pathogenic bacte-ria has increased gradually. The Pseudomonas aeruginosa and Acinetobacter baumannii,carbapenem resistant Escherichia coli and Klebsiella pneumonia,and vancomycin resistant enterococcus (VRE) has appeared.关键词
