Illustration of the phylogenetic distribution of zoonotic status, secretome (i.e. secreted proteome) size and genome size for 191 pathogenic bacteria. Zoonotic pathogens are those that can transmit between humans and animals. Large genomes and secretomes are those greater than the median and small are less than or equal to the median. Note that the tree is ultrametricized for illustrative purposes only.
