Branhamella catarrhalis can be distinguished from Neisseria spp. by the presence of butyrate esterase. This enzyme can be rapidly detected when 4-methylumbelliferyl butyrate is used as the substrate. All B. catarrhalis strains tested gave a positive fluorescence reaction within 5 min, while Neisseria spp. remained negative, even after 18 h of incubation.
卡他布兰汉菌可通过丁酸酯酶的存在与奈瑟菌属相区分。当以4-甲基伞形酮丁酸酯作为底物时,这种酶能够被快速检测到。所有测试的卡他布兰汉菌菌株在5分钟内均给出阳性荧光反应,而奈瑟菌属即便在培养18小时后仍为阴性。
