title: beta-Lactamases of Branhamella catarrhalis and their inhibition by clavulanic acid.
abstract: Three of four clinical isolates of Branhamella catarrhalis from Belgium produced a beta-lactamase identical to enzymes previously reported to occur in French and British isolates of this organism. One strain, however, produced a new type of beta-lactamase. Both beta-lactamase types were readily inhibited by low concentrations of clavulanic acid.
