Defensin resistance is not the only virulence characteristic controlled by the PhoP -PhoQ regulon because mutations in pagC , as well as ones in the phoP locus that resulted in constitutive pag activation (phenotype PhoPc ), had no effect on defensin resistance , even though they rendered the organism avirulent and deficient in survival within macrophages .
