摘要:

目的:分析泌尿系念珠菌感染的菌种分布特征和对常用抗真菌药物的耐药率,为临床合理选择抗真菌药物提供依据。方法:回顾性分析微生物实验室中段尿培养结果,对念珠菌培养和药敏试验结果进行归纳总结。结果:念珠菌培养结果依次为白念珠菌36株(38.7%),热带念珠菌18株(19.3%),光滑念珠菌15株(16.1%),近平滑念珠菌12株(12.9%),克柔念珠菌6株(6.5%),其它念珠菌6株(6.5%);主要来源于50岁以上人群;女性多于男性(66.7% vs. 33.3%);标本主要来源于泌尿外科(29.0%)、ICU(23.6%)和神经内科(19.3%)。大部分念珠菌对氟胞嘧啶和两性霉素B有较高的敏感性,其中白念珠菌对两性霉素B、氟胞嘧啶、氟康唑、伏立康唑和伊曲康唑的敏感性分别为97.2%、91.7%、58.4%、50.0%和30.6%。结论:泌尿系念珠菌感染以白念珠菌为主。临床应根据药敏试验结果合理选择抗菌药物,同时,在治疗泌尿系念珠菌感染时,应加强老年人、女性患者的管理。

Objective To analyze both distribution feature of Candida from urinary system and its resistance rate of conventional antifungal drugs, to provide guideline of rational antifungal drug administration. Methods Urine specimens were inoculated culture while both Candida species and drug sensitive results were reviewed and analyzed. Results Among all Candida species, c. albicans accounted for 36 strains(38.7%), c. tropicalis 18 strains(19.3%), c. glabrata 15 strains(16.1%), c. parapsilosis 12 strains(12.9%), c. kruser 6 strains(6.5%) and other Candida 6 strains(6.5%). Candida species isolated mainly from the older population aged over 50 years,;Female more than male(66.7% vs. 33.3%); clinical departments of Urinary Surgery(29.0%), ICU(23.6%) and Neurology(19.3%). Most Candida species were more sensitive to both flucytosine and amphotericin B than to other antifungal drugs,which the sensitive rates of c. albicans to amphotericin B, flucytosine, fluconazol, voriconazole and itraconazole were 97.2%, 91.7%、58.4%, 50.0% and 30.6%. Conclusions Main Candida species of urinary infection is c. albicans. Antifungal drugs are used by drug sensitive results, meanwhile, older or female patients should strengthen medical care.
