摘要

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.
