Model for effects of LPS OAg length on functions of T3SS. The efficiency of invasion of host cells is impaired by the presence of LPS species with L- and VL-OAg. However, the presence of these LPS species provides protection against antimicrobial factors of the host. In contrast, the OAg length does not interfere with the function of the SPI2-T3SS during the intracellular life of Salmonella and has no effect on flagellum-mediated motility.
