Fig 2. Relationship between pneumococcal carriage densities and IL-17A levels (A) Pneumococcal nasopharyngeal (NP) carriage densities in all 65 children from Fiji was measured by qPCR.
IL-17A was measured by multiplex bead array. One child was removed from the analysis as an outlier (Carriage density = 1.65x105 CFU/ml, IL-17A = 1710pg/ml). The correlation with the outlier was R = -0.19, p = 0.126. Correlation between IL-17A and children with low pneumococcal carriage density (B; N = 27) or children with high pneumococcal carriage density (C; N = 27). The Spearman test was used to correlate children with pneumococcal carriage density and IL-17A levels.
