Lack of immunoglobulin A1 protease production by Branhamella catarrhalis.

D T McLeod, M J Croughan, F Ahmad, R P Brettle, M A Calder.   

Abstract

Clinical isolates of Branhamella catarrhalis from the sputum of 20 patients with acute bronchopulmonary infection were examined for synthesis of immunoglobulin A1 protease by immunoelectrophoresis. Ten strains produced beta-lactamase, and 10 were beta-lactamase negative. None of the strains demonstrated immunoglobulin A1 protease activity despite the fact that three different culture media were used.
