Differentially expressed genes (DEGs) within candidate susceptibility QTL between mice intranasally infected with S. pneumoniae, D39 and control animals.

Pulmonary gene expression 6 h post-infection is represented as fold change between infected and non-infected animals (BALB/c infection: BALB/c-infected versus PBS-treated, CBA/Ca infection: CBA/Ca infected versus PBS-treated), between PBS-treated control animals (BALB/CBA: BALB/c versus CBA/Ca PBS-treated) and between infected BALB/c and infected CBA/Ca (BALB/CBA infection).
