Fig. 1From: High pneumococcal density correlates with more mucosal inflammation and reduced respiratory syncytial virus disease severity in infantsPneumococcal presence does not correlate with RSV load, inflammation or disease severity. Viral load (a) and MMP-9 and IL-6 (b) were compared between the group positive for S. pneumoniae and the group negative for S. pneumoniae. Data shown are median ± IQR. Data were tested for significant differences using a Mann–Whitney U test. Pneumococcal presence was compared between the three severity groups (c). Differences in bacterial colonization rates were compared using Chi-square tests. When significant differences were found, Fisher’s exact tests were performed to specify which groups differed significantly. The moderately ill infants had a significantly higher colonization rate compared to the mildly infected infants (***p < 0.001)Back to article page
