Burns bath 3 floor trap and metagenomic read abundance profiles: (a) an example of the biomass uncovered under the floor trap in a Burns Unit bathroom. Areas of high biomass (such as this one) were targeted for environmental screening. (b) Each column shows the relative abundance of paired-end reads for each environmental sample that were classified at a bacterial genus level by comparing against a database of bacterial genomes from RefSeq. Only bacterial genera with a relative abundance >0.5% are shown as distinct. Genera with an abundance of <0.5% are grouped together as ‘Other’ (grey). Boxes outlined in black represent abundance of ‘ Acinetobacter ’.
