Pathogenic bacteria for human and animals have developed sophisticated weapons, termed virulence factors, to ensure their replication and persistence into their hosts. The authors in this volume show a synthesis on how the various host cellular Rho GTPases activities are manipulated by bacteria to fulfil their virulence.
