A microbiologist is attempting to determine the size of a microbial population and has employed several methods.She noticed that the direct count she obtained using a counting chamber and microscope was much higher than her estimate from doing a viable plate count.This discrepancy was encountered during multiple trials.What is the most likely reason for the discrepancy?

The most likely reason for the discrepancy is that the organisms were not readily cultured on the viable count, either because many were dead or because the medium and growth conditions used for the viable count will not support the growth of the microorganism. This is a common occurrence, as not all microorganisms can be grown on all types of media, and some may be dead or dormant and not able to grow on the conditions used for the viable count. The direct count method, although less accurate, does not require cultural detection and includes both living and dead cells.
