Abstract

For successful infection, secretes and injects effector proteins into host cells by two distinct type three secretion systems (T3SSs) located on pathogenicity islands (SPIs)-1 and -2. The SPI-2 T3SS is involved in intracellular survival of serovar Typhimurium and systemic disease. As little is known regarding the function of the SPI-2 T3SS from serovar Typhi, the aetiological agent of typhoid fever, we investigated its role for survival in human macrophages. Mutations in the translocon (), basal secretion apparatus () and regulator () did not result in any reduction in survival under many of the conditions tested. Similar results were obtained with another Typhi strain or by using human primary cells. Results were corroborated based on complete deletion of the SPI-2 T3SS. Surprisingly, the data suggest that the SPI-2 T3SS of Typhi is not required for survival in human macrophages.
