The surge in the prevalence of Multidrug-Resistant (MDR) Gram-negative bacterial infections with limited treatment led to colistin reusing treat MDR infections. This study aimed determine economical, simple, and reliable susceptibility testing methods as an alternative microdilution technique. We compared seven methods, including quantitative qualitative, namely: Disk diffusion, E-test, ComASPT...

Acid production by certain yeast species through the fermentation of glucose was used as the basis of an in vitro test for measuring susceptibility of these organisms to 5-fluorocytosine. Serial dilutions of 5-fluorocytosine in yeast nitrogen base broth, with bromothymol blue indicator dye, were made on microtiter plates. A fixed-concentration suspension of yeast cells was added to successive w...

An evaluation of broth dilution antifungal susceptibility tests was performed by determining both the micro- and macrodilution MICs of amphotericin B, flucytosine, fluconazole, ketoconazole, and cilofungin against 38 isolates of Candida albicans, Candida lusitaniae, Candida parapsilosis, Candida tropicalis, Cryptococcus neoformans, and Torulopsis glabrata. The following preliminary antifungal w...
