RHOA and infection: The amount of GTP-RhoA in the ΔespO1-2 single mutant-infected cells at 1 h post-infection was greater than that in the ΔespO1-1 single mutant-infected cells at 1 and 3 h post-infection and comparable to that in WT- and ΔespO1-1ΔespO1-2 double mutant-infected cells at 1 h post-infection.
