Collaborative Study to evaluate a Total Bacteria Count A i Q tit ti R l Ti PCRAssay using Quantitative Real‐Time PCR
A collaborative study was undertaken to demonstrate the precision and accuracy of a total bacteria count (TBC) assay developed to run withaccuracy of a total bacteria count (TBC) assay developed to run with commercially available PCR reagents and a rapid thermocyclingplatform. The TBC assay can be completed within one hour. The TBC assay has many applications for enhanced HACCP applications
The overall conclusions are that all the labs performed well in constructing the standard curve and had some variance with the unknown samples. However, the results show that all collaborators
f ll d h C if b i l l d lsuccessfully used the TBC assay to quantify bacterial load accurately within one hour. The TBC assay can be used for a rapid real‐time measure of bacteria in many diverse applications and support HACCP for real‐time statistical process control.
