NMDS visualization of bacterial abundance determined by qPCR in ear discharge swabs. Non-Metric Multidimensional Scaling (NMDS) for visualization of the similarity of samples based on bacterial abundance in individual ear discharge swabs. Data points are coloured according to a dichotomous abundance measure of >105 cells/ml or <105 cells/ml for a) H. influenzae; b) S. pneumoniae and c) M. catarrhalis. a) Data points coloured according to H. influenzae abundance; green (<105 cells/ml) or red (>105 cells/ml). b) Data points coloured according to S. pneumoniae abundance; green (<105 cells/ml) or pink (>105 cells/ml). c) Data points coloured according to M. catarrhalis abundance; green (<105 cells/ml) or blue (>105 cells/ml).
