[摘要] 目的 對筆者所在醫(yī)院兒科分離的金黃色葡萄球菌進行耐藥性分析,為臨床合理使用抗菌藥物提供依據(jù)。 方法 回顧性分析筆者所在醫(yī)院兒科分離的233株SAU標本來源及臨床科室分布情況,并進行耐藥性分析;采用VITEK-2 COMPART儀器進行藥敏試驗,苯唑西林篩選出耐甲氧西林金黃色葡萄球菌。 結(jié)果 233株SAU在痰標本及兒科重癥監(jiān)護室檢出比例最大,分別為68.67%和31.33%;共檢出MRSA 40株,其檢出率17.17%;在SAU中利奈唑烷、利福平、莫西沙星、喹奴普汀/達福普汀和萬古霉素耐藥率均為0;MRSA對紅霉素、氯潔霉素、四環(huán)素、環(huán)丙沙星的耐藥率顯著高于甲氧西林敏感金黃色葡萄球菌,差異有統(tǒng)計學意義(P<0.05)。 結(jié)論 臨床在確診SAU感染時,應(yīng)區(qū)別對待MSSA和MRSA,及時、合理使用抗生素預(yù)防和控制感染。

[Abstract] Objective To analyze the drug-resistance of Staphyloccocus aureus infection in authors' hospital pediatrics and provide evidence for clinically reasonable use of antibiotics. Methods Investigate to analyze the specimen source and the clinical distribution of 233 SAU strains; BioMerieux VITEK-2 COMPART was used to identify isolating strains and performe antibiotic susceptibility testing, Methicillin- resistant S.aureus was sreened by resistant oxacillin. Results The proportion of the sputum specimens and the PICU department are the highest ;Isolating rate of MRSA was 17.17%; linezolid, rifabutin, moxifloxacin, quinupristin/dalfopristin and vancomycin in SAU were no drug resistance.; Diffence in drug-resistant rate of erythromycin, clindamycin, tetracycline, ciprofloxacin between MRSA and methicillin-sensitive S.aureus is statistically significant (P<0.05), and MRSA group is much higher drug-resistant rate. Conclusion When diagnosing infection from SAU and making a difference between MSSA and MRSA,we should use the antibiotics timely and reasonably to the prevention and control of infection.

金黃色葡萄球菌(staphyloccocus aureus,SAU)是人類的一種重要病原菌,也是兒科臨床較為常見的病原菌之一。SAU對抗菌藥物的多重耐藥性日趨嚴重,有學者將SAU引起的感染與艾滋病和病毒性乙型肝炎一起并稱世界三大感染性疾病,并將SAU稱之“超級細菌”[1]。近年來隨著廣譜抗生素的廣泛應(yīng)用,耐甲氧西林的金黃色葡萄球菌(MRSA)檢出率逐年增加[2],其高致病性和多藥耐藥性,已引起世界衛(wèi)生組織(WHO)和許多國家的高度重視[3]。本研究對2011年4月~2012年6月筆者所在醫(yī)院兒科臨床分離出的233 株金黃色葡萄球菌,從標本來源、科室分布以及藥敏情況進行研究分析,旨在為臨床合理使用抗生素提供有效可靠的依據(jù)?!?br>
