A rapid, radiometric method was developed to determine the susceptibility of filamentous fungi to amphotericin B. The rapid, radiometric method depended on measurement of the inhibition of 14CO2 production in the presence of amphotericin B. Thirty isolates of filamentous fungi were tested by the rapid, radiometric method and a reference agar dilution method. There was 93% agreement between the two methods when an 80% or greater decrease in CO2 production was used to calculate the minimal inhibitory concentration with the rapid, radiometric method. Minimal inhibitory concentrations, based on 80% decrease of CO2 production, were achieved within 24 h of incubation with all of the fungi tested.
开发了一种快速放射性方法来测定丝状真菌对两性霉素B的敏感性。这种快速放射性方法依赖于在两性霉素B存在的情况下测量14CO2产生的抑制情况。用快速放射性方法和参考琼脂稀释法对30株丝状真菌进行了测试。当用快速放射性方法以二氧化碳产生减少80%或更多来计算最低抑菌浓度时,两种方法的一致性为93%。基于二氧化碳产生减少80%的最低抑菌浓度,在对所有测试真菌培养24小时内即可获得。
