In the validation experiment, the cell number of each strain calculated
from their respective equation and the actual cell number determined
by plate counting showed good consistency (P-value N 0.05)
(Table 1). The impedancemethod based on theM-value enabled reproducible
estimates of Y. enterocolitica cell numbers in planktonic culture.
Since the calibration equations are strain specific, a separate calibration
needs to be developed for every individual strain.
