The present method is sensitive enough to detect ∼100 bacterial CFU/mL but has the potential to estimate even lower concentrations with increased imaging and computation times. It could easily be tailored to estimate different species of pathogens, such as Escherichia coli O157, Listeria innocua, Staphylococcus aureus, Enterococcus faecalis, and Bacillus anthracis, on samples similar to those in real-time contamination scenarios. The method was validated against conventional microbiological techniques such as the use of optical density, flow cytometry, and quantitative real-time PCR (qPCR). Both the estimation and imaging parameters were optimized to reduce the estimation error ( E, %) to close to ±5%.

Herein, we explore a method that combines electron microscopy (EM) and image-analysis techniques and allows both visualization and quantification of pathogenic bacteria adherent even to complex nonuniform substrates. A visual quantification, therefore, may compliment such techniques by providing additional information and support better management decisions in the event of outbreaks. Conventional signal-based microanalytical techniques for estimating bacterial concentrations are often susceptible to false signals.
