Abstract: Inoculating systems/devices, methods for inoculating a target, and coating methods are disclosed. An example inoculating system may include an inoculating member having a transfer region and a handle region. A pre-determined quantity of viable microorganisms may be disposed on the transfer region. The inoculating member may be configured to transfer the pre-determined quantity of viable microorganisms to a target during an inoculation operation without having to rehydrate the pre-determined quantity of viable microorganisms prior to the inoculating operation.

Abstract: An ultraviolet (UV) light test device is suitable for ascertaining the efficacy of a germicidal UV light source. The UV light test device includes a population of viable microbial material having a residual water content of less than five percent. The population of viable microbial material is encapsulated in a container. At least a portion of the container is formed of a UV light transmissible material such that UV light from the germicidal UV light source is able to contact the population of viable microbial material.

Abstract: Methods of evaluating the antimicrobial efficacy of a hard surface disinfectant or sanitizer and test articles are disclosed. An example method may include removing a preserved antimicrobial test article from a sealed container. The preserved antimicrobial test article may comprise a non-water soluble substrate and a thin microbial layer attached to the substrate comprising viable microbial material, a stabilizing mixture, and a residual water content of less than 5.0%. The method may also include contacting the preserved antimicrobial test article with a predetermined amount of the test substance without rehydrating the preserved microbial article and without detaching the layer comprising the viable microbial material from the substrate prior to contact with the test substance.

Abstract: Dehydrated biofilm assemblies and methods for manufacturing dehydrated biofilm assemblies are disclosed. An example dehydrated biofilm assembly may include a dehydrated biofilm assembly for use in antimicrobial testing. The dehydrated biofilm assembly may include a substrate and a dehydrated biofilm secured to the substrate. The dehydrated biofilm may include a viable population of micro-organisms. The dehydrated biofilm may be configured to retain securement to the substrate and exhibit a biofilm phenotype upon hydration.
