Detect butyrate esterase to presumptively identify Moraxella catarrhalis using the reagent-impregnated Catarrhalis Test Disk. Moraxella catarrhalis is an important pathogen. Yeun et al. have reported that the isolation of M. catarrhalis from routine sputum cultures is associated with clinical infection.^2 Rapid identification of this organism is important, since most strains produce beta-lactamase and are resistant to penicillin and ampicillin.

This color change allows rapid detection of M. catarrhalis.Not all products are available for sale in all territories.
