Pleural infection is predominately a polymicrobial disease

(A) The histograms show the counts of detected pathogens in each sample within each of the five groups, based on dominant pathogen abundance. (B) Heatmap of unsupervised hierarchical clustering using the Bray-Curtis distance and the complete-linkage method; the colour of the first column denotes the bacterial class of the most abundant pathogen in the sample; each row is a sample and each column is a pathogen group; the colour of each cell represents the abundance (proportion of bacterial reads) of each pathogen group in each sample; red represents high and dark blue low abundance.
