Discussion
Our analysis revealed both similarities and differences in the expression of "early", "late", and "delayed" competence between in vitro versus during pneumonia-derived sepsis. Our results may reveal new aspects of pneumococcal competence biology.
Methods
We conducted a comparative gene expression analysis of pneumococcal competence development in vitro versus in vivo during pneumonia-derived sepsis in mice. We examined existing RNA-Seq data and performed validation using RNA obtained from an independent replicate experiment.
