Abstract: Using Escherichia coli as a model bacterium, we tested a photon-counting method for enumeration of bacteria. This method is based on the principle that microscopic sized luminous particles in a wide field can be directly detected and counted using a photon-counting TV camera without the use of a microscope. E. coli cells were labeled with peroxidase and luminescence induced by adding a luminol-based reaction mixture. The number of luminous spots in the TV images was in good agreement with the number of bacterial colonies grown from labeled cells. The results show that our method provides a rapid and easy microbial counting system for such purposes as clinical diagnosis, microbial analysis in food, and environmental assessment.
