Abstract

The serial-dilution assay is a standard microbiological method for estimating the density of organisms in a solution. The commonly used interval-estimation procedures of Woodward and deMan are described and compared. A new method for the calculation of two-sided confidence intervals, which is superior to the standard procedures, is presented. The computations are illustrated for a decimal dilution assay with three samples at each of three dilutions.

摘要

连续稀释测定法是一种用于估计溶液中微生物密度的标准微生物学方法。文中描述并比较了伍德沃德和德曼常用的区间估计程序。提出了一种计算双侧置信区间的新方法，该方法优于标准程序。以十进制稀释测定法为例进行了计算说明，在三个稀释度下每个稀释度有三个样本。
