Abstract: The present invention is directed to kits, methods, and compositions for the characterization of various microorganisms. In particular, the present invention is suited for the characterization of commonly encountered microorganisms (e.g., E. coli, S. aureus, etc.), as well as commercially and industrially important organisms from various and diverse environments. For example, the kits of the present invention are particularly suited for the growth and characterization of the actinomycetes and fungi.

Abstract: The present invention is directed to methods and compositions for the characterization of various microorganisms. In particular, the present invention is suited for the characterization of commonly encountered microorganisms (e.g., E. coli, S. aureus, etc.), as well as commercially and industrially important organisms from various and diverse environments. For example, the present invention is particularly suited for the growth and characterization of the actinomycetes and fungi. The methods employ a testing system wherein an aqueous suspension of microorganisms is introduced to one or more test substrates comprising redox purple (8-hydroxy-11-methyldibenz-?b,e!?1,4!oxazepin-2-(11H)-one) and a gelling agent. The methods detect the response of the microorganisms to the test substrates. A testing device comprising a plurality of testing wells is well suited for the present invention.

Abstract: Testing of samples in a small, closed, and easy-to-fill device. Simultaneous filling of a large number of test wells using a novel gas-venting design, allowing for multiparameter testing and/or identification of bacteria.

Abstract: New derivatives of S.sub.P - and R.sub.P -configures cyclic guanosine-3',5'-phosphorothioates and their physiologically and pharmaceutically acceptable salts according to the general formula ##STR1## are cell membrane permeable inhibitors (R.sub.P -isomers) and stimulators (S.sub.P -isomers) of cyclic GMP-dependent protein kinase which are resistant against phosphodiesterase degradation and suitable as ligands for affinity chromatography of cyclic nucleotide-dependent binding proteins.

Abstract: The present invention is directed to methods and media for the isolation and presumptive identification of various bacteria. In particular, the organisms commonly associated with urinary tract infections are distinguished based on their colonial morphology and color.

Abstract: The present invention relates generally to differential carbon source metabolism in the genus Listeria, metabolic, biochemical, immunological and genetic procedures to measure said differential carbon source metabolism and the use of these products to detect, isolate and/or distinguish species of the genus Listeria as well as detect, isolate and/or distinguish strains of species of Listeria. The present invention also contemplates test kits and enrichment media to facilitate these procedures.
