Abstract:
OBJECTIVE To understand flora distribution and four antifungal drugs′in vitro antifungal activity of deep fungi in nosocomial infection in order to provide help to clinics.METHODS Fungi were cultured and isolated by routine procedure which identified by VITEK microbe automatic system.Drug susceptibility test used Rosco paper disk diffusion and broth dilution method with NCCLS M27-A.RESULTS Totally 156 strains with 9 species of deep fungi that main fungi were Candida albicans,and C.tropicalis with 57.69%,and 31.41%,respectively,were isolated from nosocomial infection.The major isolating rates of clinical infection specimens were from respiratory,cardiovascular surgery,and neurological departments with 26.28%,12.18%,and 9.62%,respectively.The main infection specimens were from respiratory tract and urinary tract with 71.15% and 16.67%,respectively.Drug resistance rates to fluconazole,amphotericin B,itraconazole,and ketoconazole with Rosco paper disk diffusion were 23.08%,2.56%,12.18%,and 17.36%,MIC90 were 64.0,2.0,8.0,and 16.0mg/L,respectively.CONCLUSIONS The main deep fungi are C.albicans and C.tropicalis.Antifungal activity of amphotericin B is the highest than others.The drug resistance rate to fluconazole is more and more higher.Clinics should use antifungal drug rationally in accordance with drug susceptibility test results.
