Radiometric determination of the concentration of amphotericin B in body fluids
Antimicrobial Agents and Chemotherapy
|December 1, 1977
Abstract:
A new assay was developed to determine the concentration of amphotericin B in body fluids. The Bactec radiometric system was used to measure CO(2) production by a test strain, Candida albicans MDA 448, in the presence of amphotericin B. After 5-h incubation, drug concentrations as low as 0.2 mug/ml could be detected. The results are comparable to those of the commonly used agar diffusion assay with Paecilomyces varioti.
