WebButyrate Disk test is also known as Tributyrin test. It is a rapid test used to identify Moraxella catarrhalis and differentiate it from Neisseria catarrhalis. When an organism can produce butyrate esterase, it can hydrolyze bromochlorindolyl butyrate releasing indoxyl, and can be noticed through a change in color due to exposure of indoxyl from oxygen. WebJul 19, 2024 · The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract.
