A major group of virulence factors are proteins that can control the activation levels of GTPases. There are two ways in which they act. One is by acting as a GEF or GAP, and proceeding to look like a normally eukaryotic cellular protein. The other is covalently modifying the GTPase itself. The first way is reversible; many bacteria like Salmonella have two proteins to turn the GTPases on and off.
