ABSTRACT
OBJECTIVE To get the message of drug sensitivity and characteristic of Candida infecting patients in our hospital. METHODS The CHROMagar candida color medium was applied to isolate and identify Candida strains.Drug sensitivity was analyzed by the K-B slip diffusion method. RESULTS Totally 393 strains of Candida in our hospital were isolated in the three years,including Candida albicans;C.tropicalis;C.glabrata;(C.krusei);Cryptococcus neoformans and the others;and their infection rate was 63.10%,12.47%,9.41%,8.40%,1.53%,and 5.09%,respectively.Among all strains,156(39.69%) strains were isolated from sputum,(66(16.79%))from stool,45(11.45%) from urine,38(9.67%)from leucorrhea,and 34(8.65%)from throat swabs.Sensitivity results to nine antifungals showed that 5-flucytosine,fluconazole,clotrimazole,amphotericin B,and nystatin had higher drug sensitivity to these fungi. CONCLUSIONS Isolated rate of Candida is higher from clinical samples.Drug sensitivity of different Candida to various antibiotics is different.Culturing and drug sensitivity of Candida should be put on important place and antibiotics should be used reasonably based on drug sensitive test to reduce drug resistance.
