BRI makes available phylogenies of antibiotic resistance genes, primarily ß–lactamase genes. Click the blue buttons in the navigation bar at the left to select the page you are interested in. The Phylogenies page discusses the phylogenies in general, the Serine and Metallo ß-lactamase pages discuss these distinct classes of ß-lactamases.

The Ambler Classification page discusses the basis of classifying ß-lactamases and some shortcomings of the present implementation of the Ambler system

BRI also makes available some software that is useful for phylogeny reconstruction. Click the Software button for descriptions of the software. You can download the software from that page.

Links provides some links of interest to phylogeneticists, especially those interested in antibiotics resistance genes
