Disruption phenotypei
Double espI-eccD1 mutants abolish EsxA and EsxB secretion, but not their expression (PubMed:14557547). Disruption abolishes EsxA and EsxB secretion, but not their expression (PubMed:14557536). Results in a lack of antigen specific immunogenicity and leads to attenuated virulence (PubMed:16368961). Mutants exhibit defects in bacterial growth during the acute phase of C57BL/6 mouse infection, but survive for 140 days despite a wild-type bacterial load in the lungs at 100 days post-infection, suggesting the pathway is required for virulence (PubMed:14557536). Nearly wild-type levels of IL-12 p40 (IL12B) and TNF-alpha are produced by infected murine macrophages, while the nitric oxide response is about 50% reduced (PubMed:14557536). Mouse macrophages do not induce cGAMP production, and thus do not sense bacterial DNA correctly to induce the innate immune response (PubMed:26048137).4 Publications
