Chlamydia trachomatis represents a significant health concern in the United States. A significant burden exists due to prevalence and the combined health and socioeconomic impact of acute and chronic disease. Chlamydiae are obligate intracellular parasites that undergo a complex developmental cycle. Chlamydia express a type III secretion system (T3SS), and based on analogy with other T3SS-expressing pathogens, this mechanism likely contributes significantly to overall pathogenesis. Although definitive association of T3S with chlamydial virulence has proven difficult, the newly-acquired ability to genetically manipulate chlamydiae has opened new doors for progress. We present preliminary data describing the first ever Chlamydia-specific suicide vector and propose to leverage this new approach to target T3SS genes for inactivation. Specifically we will further develop the suicide vector system and directly create null mutations in specific T3S effector genes. We also propose approaches to conditionally inactivate T3S capability. At the end of these studies, we will have established molecular tools that will benefit the entire Chlamydia community. In addition, we will gain a better understanding of how the T3SS contributes to chlamydial virulence.
