From: Dysbiosis of upper respiratory tract microbiota in elderly pneumonia patients
Bacterial density in the oropharynx of elderly and adult controls and pneumonia patients. For each group, the bacterial density per sample is depicted in pg μl−1. Bars represent geomean and 95% CI of geomean per group. 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 Mann–Whitney U-tests; *P⩽0.05; **P⩽0.01; ***P⩽0.001; ****P⩽0.0001. Healthy subjects are depicted in light gray, patients are shown in dark gray.
