Microarray analysis of Streptococcus pneumoniae gene expression changes to human lung epithelial cells.

abstract：:The adherence of Streptococcus pneumoniae to epithelial (A549) lung cells was studied and the bacterial binding distribution was found to be nonrandom (non-Gaussian). Analysis of the dependency of bacterial binding on the cell cycle of A549 cells revealed that approximately 1.8 times more bacteria bind to G2 cells tha...
