Rapid identification of Branhamella catarrhalis with 4-methylumbelliferyl butyrate.

J. Clin. Microbiol. 26 , 1227, (1988)

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. ...
