title: Quantitation of the tetramethyl-p-phenylenediamine oxidase reaction in Neisseria species.
abstract: The tetramethyl-p-phenylenediamine oxidase reaction commonly used in the Kovacs oxidase test was quantitatively estimated for various Neisseria species employing standardized resting cell suspensions. This genus of microorganisms exhibited very high tetramethyl-p-phenylenediamine oxidase rates comparable to that of Azotobacter and Pseudomonas, and this reaction was found to be a valid measurement for the respiratory capability possessed by this group of organisms.
