Comparison of innate immune response in the middle ear fluid (MEF) in relation to the presence of Streptococcus pneumoniae (Spn) or nontypeable Haemophilus influenzae (NTHi) of children who with stringently defined otitis prone (sOP) versus children who were not otitis prone (NOP) in which more than twofold differences were observed. Black bar shows similar trend in gene expression in relation to S. pneumoniae and NTHi. Gray bar represent no statistical significance was found and solid box bar represents genes that showed expression in S. pneumoniae only. *Significant difference (p < 0.05) was found in children who were sOP compared with children who were NOP.
