The number of positive (yellow) tubes from the five tubes in the first, second and third dilutions should be noted, then matched to the MPN table (Table 1). Based on the result, an estimation is made on how many bacteria are found in 100 ml of sample. The major weakness of MPN methods is the need for large numbers of replicates at the appropriate dilution to narrow the confidence intervals. However, it is a very important method for counts when the appropriate order of magnitude is unknown a priori and sampling is necessarily destructive. See also.
