110株念珠菌的菌种鉴定及药敏试验

目的:了解我院皮肤、粘膜念珠菌感染的菌种分布及其对两性霉素B、酮康唑、咪康唑、伊曲康唑、氟康唑、5-氟胞嘧啶及特比奈芬的体外敏感性.方法:收集临床110株念珠菌标本,采用科玛嘉显色培养基及API20C鉴定菌种,微量稀释念珠菌药敏试剂板检测其药物敏感性.结果:110株真菌中白色念珠菌94株,热带念珠菌6株,克柔念珠菌4株,光滑念珠菌4株,近平滑念珠菌2株.对酮康唑、咪康唑、伊曲康唑、氟康唑、5-氟胞嘧啶及特比奈芬的耐药率分别为0%、18.28%、1.81%、5.45%、3.63%及94.55%.结论:我院念珠菌感染仍以白念珠菌为主,对常用抗真菌药物呈不同程度的耐药,应建立真菌常规菌种鉴定及药敏试验,指导临床合理用药.

Susceptibility testing and strain identification of Candida species

Objective:To identify the strain and to study the in-vitro susceptibilities of Candida species collected from clinical samples of skin and mucosa to Amphotericin B,Ketoconazole,Miconazole,Itraconazole,Fluconazole,5-Flucytosine and Terbinafin. Methods:110 clinical isolates of yeasts were identified by CHROMAGAR and API20C, meanwhile, the susceptibility to six antifungal drugs was examined by microdilution method using Sensititre Yeast One panels. Results:There were 94 C.albicans, 6 C.tropicalis,4 C.krusei,4 C.glabrata,and 2 C.parapsilosis among 110 isolates of yeasts.There were 0.91%,1.81%,18.28%,1.81%,5.45%,3.63% and 94.55% of isolates displaying resistance to Amphotericin B,Ketoconazole,Miconazole,Itraconazole,Fluconazole,5-Flucytosine and Terbinafin, respectively.Conclusions:C.albicans is the main infection strain in our hospital,and candida species display different resistance to six antifungal drugs. It is necessary to test strain identification and susceptibility of candida species to guild the rational clinical drug use.
