Prevalence and polymorphism of genes encoding translocated effector proteins among clinical isolates of Salmonella enterica

Pathogenic Salmonella enterica strains are capable of causing local and/or systemic infections. They employ two type III secretion systems to translocate an array of virulence-associated proteins (effector proteins) directly into the cytosol of target cells of the host. Earlier data had shown that changes in the repertoire of translocated effector proteins may contribute to the adaptation of Salmonella strains to new hosts and to the emergence...
