In order to study pneumococcal gene expression changes after incubation with host epithelial cells, logarithmic-phase grown S. pneumoniae strains (82 and R6) were incubated with host epithelial cells (A549 and ETEC) in T75 cell culture flasks at an MOI range of 10:1 ~ 50:1. After incubation for 1 h ...
