Figure 5From: Analysis of the Rickettsia africae genome reveals that virulence acquisition in Rickettsia species may be explained by genome reductionSchematic representation of the genes conserved in R. africae but lost by highly pathogenic rickettsiae. Genes highlighted in yellow are upregulated at 37°C. The state of a gene is represented by a small box colored in green (full-length), blue (pseudogene), red (fragment), orange (remnant) or black (absent). Gene numbers are indicated in the left column.Back to article page
