Same sample. Same method. Different colony counts. Why?
Even when the sample, Petri dish, and testing method are the same, colony counting results can still vary.
Several factors may contribute to these differences, including:
๐น Small colonies that are difficult to distinguish
๐น Colonies growing too close together
๐น Eye fatigue during long observations
๐น Differences in interpretation between analysts
As the number of colonies increases, the possibility of counting variations may also increase.
To support more consistent and efficient colony counting, laboratories often use a colony counter that helps improve observation and recording processes.
