The flat sides of the organism abut against each other. M. catarrhalis is easily overlooked in culture because it is phenotypically identical to Neisseria in Gram stain and on culture plates. M. catarrhalis is resistant to amoxicillin and 1st generation cephalosporins. Activity of 2nd generation cephalosporins is variable and may be more bacteriostatic than cidal. Resistance to TMP/SMX increasing. It is generally susceptible to amoxicillin-clavulanate, cefixime, ceftriaxone, tetracyclines, macrolides, and quinolones. The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc).
