The scale of the Class C ß-lactamases phylogeny makes it impossible to visualize the detail of the ß-lactamases from Citrobacer freundii (CFRE). Those gene recently moved onto plasmids and have diversified, albeit only slightly, from each other. This page therefore includes both the phylogeny of the Class C ß-lactamases, and a separate, detailed phylogeny of the CFRE clade within the Class C ß-lactamases.
