Abstract: The disclosure is directed at a system and method for rapid detection of low level bacteria in a growth medium. The method is directed at a two-stage process whereby a growth medium is incubated along with a first test formulation component for a predetermined period of time. After the incubation period, a second test formulation component is added to the growth medium to determine if there is a bacteria in the growth medium.

Abstract: The disclosure is directed at a system and method for non-microbial prediction of antimicrobial efficacy of an antimicrobial item, such as, a metal surface or materials impregnated with biocidal metal ions or nanoparticles. A test formulation is applied to a surface of interest and a color change of the test formulation is then analyzed and then correlated with antimicrobial activity.

Abstract: An apparatus for use with a particulate fluid sample such as a bacterial fluid sample. The apparatus includes a sample receiver assembly, a particulate removal assembly and a fluid moving assembly. The particulate fluid sample can include bacteria in water. The particulate removal assembly is configured to filter out the particulates. The amount of bacteria filtered out may be measured. The apparatus concentrates the particulate matter to a measurable level by removing fluid from the s.
