Patterns in relative abundance of frequently occurring OTUs in elderly and adult controls and pneumonia patients. Relative abundance (percentage) is depicted per individual for Gemellales, Streptococcus (pseudo)pneumoniae, Neisseria, Rothia, Veillonella, Prevotella melaninogenica, Haemophilus, Leptotrichia and Lactobacillus. Statistically significant differences between groups (healthy elderly vs elderly pneumonia (circles), healthy adults vs adult pneumonia (triangles) and healthy adults vs healthy elderly) were calculated using significance analysis of microarrays with false discovery rate correction for multiple tests. *q⩽0.05; **q⩽0.01; ***q⩽0.001; ****q⩽0.0001; NS, not significant. Bars represent geomean and 95% CI of geomean per group. OTUs are color coded based on the phylum level; Firmicutes, red; Actinobacteria, yellow; Bacteroidetes, green; Proteobacteria, blue; and Fusobacteria, purple.
