Heatmaps showing differentially expressed transcripts in RBs of C. psittaci and C. abortus. From the 354 homologous genes shared between C. psittaci and C. abortus 170 were differentially expressed (Benjamini-Hochberg adjusted p-value < 0.01 and an absolute log2-fold change > 1.0) in RBs. Of these 101 are up-regulated in C. psittaci (a) and 69 in C. abortus (b). Known as well as potential virulence factors (predicted Incs and T3SS effectors) and genes with associated gene names are indicated. Hierarchical clustering was performed using hclust with regularized log transformed (rlog) gene expression values and the complete linkage method
