ABSTRACT Chromosome- and plasmid-encoded CfxA2 and CfxA3 β-lactamases were detected in Capnocytophaga spp. from oral sources in France, Norway, and the United States. Unidentified chromosome-encoded β-lactamases were present in Capnocytophaga sputigena . Nucleotide sequence analysis of the CfxA3-encoding plasmid from C. ochracea revealed an...

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.
