Annotation of homologous protein-coding genes in C. psittaci, C. abortus and W. chondrophila. (a) Venn diagram showing the number of protein-coding genes that are unique or shared among C. psittaci, C. abortus and W. chondrophila. (b) The 562 homologous genes in all three pathogens are mainly involved in fundamental cellular processes, whereas the 354 genes shared only among C. psittaci and C. abortus encode mainly virulence-related genes like inclusion membrane proteins, polymorphic membrane proteins and type three secretion system effectors
