Figure 2From: Streptococcus pneumoniaeearly response genes to human lung epithelial cellsTranscriptional profiles of functional categories of genes identified in microarray analysis at 1 h incubation time period. The number of differentially regulated genes (x-axis) identified in microarray analysis in S. pneumoniae TIGR4 following incubation with A549 cells for 1 h time period. They are represented in different functional categories (y-axis) and marked with up-regulated (open bars) and down-regulated (grey bars) expressions.Back to article page
