Fluconazole disk diffusion test with methylene blue- and glucose-enriched Mueller-Hinton agar for determining susceptibility of Candida species.
نویسندگان
چکیده
A 25-microg fluconazole disk diffusion test using a Mueller-Hinton agar plate containing 2% glucose and 5 microg of methylene blue/ml (GM-MH) was compared to the macrodilution reference method for 210 Candida species. The GM-MH agar plate was read at 24 h. The predictive values of disks with susceptible, intermediate, and resistant results on the GM-MH agar plate at 24 h were 97.1, 56.3, and 76.5%, respectively.

Disk diffusion test and E-test with enriched Mueller-Hinton agar for determining susceptibility of Candida species to voriconazole and fluconazole.
BACKGROUND AND PURPOSE A simplified antifungal disk diffusion test using Mueller-Hinton agar containing 2% glucose and methylene blue 5 microg/mL (GM-MH, Clinical and Laboratory Standards Institute [CLSI] M44-A) has proved to correlate well with the standard reference test. A new azole, voriconazole, has recently been approved for clinical therapy in Taiwan. This study investigated the reliabil...

We evaluated the NCCLS M44-P fluconazole disk diffusion method in comparison with the NCCLS M27-A2 broth microdilution method for determining the susceptibility of 276 isolates of Cryptococcus neoformans. Disk diffusion testing was performed using Mueller-Hinton agar supplemented with 2% glucose and 0.5 microg of methylene blue/ml. Among the 276 isolates, 259 (93.8%) were susceptible, 16 (5.8%)...
متن کاملEvaluation of the Etest and disk diffusion methods for determining susceptibilities of 235 bloodstream isolates of Candida glabrata to fluconazole and voriconazole.
The performances of the Etest and the disk diffusion methods for testing of the susceptibilities of 235 Candida glabrata isolates to fluconazole and voriconazole were compared with that of the National Committee for Clinical Laboratory Standards (NCCLS) approved standard broth microdilution (BMD) method. The NCCLS method used RPMI 1640 broth medium, and MICs were read after incubation for 48 h ...
متن کاملDisk diffusion-based methods for determining Candida parapsilosis susceptibility to anidulafungin.
Zone diameters for anidulafungin by disk diffusion for 139 isolates of C. parapsilosis were compared with MICs by NCCLS M27-A2 broth microdilution. The comparison was poor unless the disks were prepared by dissolving anidulafungin in 1% dimethyl sulfoxide plus 0.1% Tween 80 and testing on Mueller-Hinton agar flooded with glucose and methylene blue.
متن کاملFluconazole susceptibility of Candida species in Singapore by disc diffusion test.
INTRODUCTION Resistance of Candida species to fluconazole has been increasingly reported worldwide. To date, the prevalence of resistance to fluconazole in Singapore is unknown. The aim of this study was to use a newly described agar disc diffusion method to study levels of susceptibility of Candida species to fluconazole in several hospitals in Singapore. MATERIALS AND METHODS Three hundred ...
