Catalase Test (Reaction with 3% hydrogen peroxide) When performed on a clear base medium without hemoglobin, the catalase reaction of M. catarrhalis may occur vigorously, but very rapidly and then become “negative;” persistent bubbles may not be observed. Thus, the reaction should be watched to observe a positive catalase reaction. Catalase

state that B. catarrhalis is "convincingly associated" with acute suppurative otitis mediaand sinusitis. Evidence for this comes from bacteriological studies of MEFobtained by needle aspiration through the tympanic membrane. Many cultures yielded "N. catarrhalis" (78, 135, 141, 166, 168) andB. catarrhalis (30, 184, 188, 189, 194, 265,274, 290, 305, 310).
