ABSTRACT The gene encoding a β-lactamase of Prevotella intermedia was cloned and sequenced. This gene, called cfxA2 , shared 98% identity with cfxA , the structural gene of a β-lactamase previously described in Bacteroides vulgatus . The deduced protein sequence had a K272E substitution. CfxA2 had the characteristics of class A, group 2e β-lactamases.
