Device for solid phase bacteriological testing containing test areas formed by lines of an antibacterial composition

Abstract

A device for solid phase bacteriological testing is provided having an abbent solid support surface for bacterial culture subdivided into a multiplicity of individual adjacent test areas with lines of an antibacterial composition. The lines may intersect to form a grid may be parallel to form parallel channels, and may be on a sheet of bibulous cellulose which can be impregnated with a bacterial culture. The composition is preferably water-soluble and in the form of an ink containing an aniline dye such as Brilliant Green that is inhibitory to bacteria. The support surface can include a bacterial growth medium or may be supported on a solidifying bacterial growth medium, and the medium may contain agar-agar.
