From: The taxonomic distribution of histamine-secreting bacteria in the human gut microbiome
Distribution of putative histamine-secreting bacteria across the Genome Taxonomy Database (GTDB) collection. Phylogenetic trees of (A) pyruvoyl-dependent and (B) PLP-dependent putative histamine-secreting bacteria across the 31,910 genomes of the representative GTDB collection were shown. The tip label colors represent different phyla. Stacked bar charts aligned to tree tips represent the percentages of genomes with and without HDC clusters in the species. The following red and blue numbers indicate the number of genomes with HDC present and absent, respectively
