Pulmonary burden of Mtb in Cgas-KO and Sting1gt/gt mice was unchanged from WT at 3 and 6 weeks post aerosol infection of 200 CFU of the Erdman strain, although Cgas-KO mice had late reduced survival (deaths between 100 and 200 days p.i.)while the STING mutant did not differ from WT (97). This evidence concerns the gene CGAS and infection.
