兒童泌尿道感染常見致病菌及其耐藥性分析
黃凱風  姚荊  陳彥  施穎  宋冬其


【摘要】

目的   探討兒童泌尿道感染常見致病菌的構成及耐藥特徵,為臨床合理選用抗菌藥物提供依據。
方法   對資料完整71例泌尿道感染患兒進行回顧性分析,用K-B法進行藥敏分析,並按NCCLS標準判斷細菌耐藥性。
結果   病原菌以革蘭氏陰性桿菌為主,大腸埃希菌佔50.7%,革蘭氏陽性菌佔15.5%;尿培養前3位致病菌分別為大腸埃希菌,肺炎克雷伯菌,葡萄球菌。
結論   大腸埃希菌仍是住院兒童泌尿道感染的主要致病菌,革蘭氏陽性菌感染增多,細菌耐藥現象普遍;重視泌尿道感染病原菌檢測,以藥敏試驗選用抗菌藥物進行治療十分重要。

[Abstract] 

Objective  To study the distribution of pathogens and resistance characteristics in urinary tract infections among children in our hospital and to provide basis for optimal selection of antibiotics by clinicians.
Methods    The clinical data of 71 cases of urinary tract infections in hospitalized children were analyzed retrospectively. Kirby-Bauer Method was employed, and antibiotic resistance was determined according to NCCLS standard.
Results    Gram-negative bacilli outweighed other pathogens. Escherichia coli accounted for 50.7%, Gram-positive bacteria accounted for 15.4%. Bacterial culture traced three major pathogens, namely, Escherichia coli, Klebsiella pneumoniae, and Staphylococci.
Conclusion Escherichia coli attributed to the majority of urinary tract infections in hospitalized children. There is a trend of increased proportion of Klebsiella and other enterobacteria. A substantial number of pathogens are resistant to antibiotics, some of which are multi-resistant strains. It is important to identify the pathogenic bacteria and select antibiotics according to drug susceptibility.
