We developed a live, fully attenuated Mycobacterium tuberculosis vaccine candidate strain with two independent attenuating auxotrophic mutations in leucine and pantothenate biosynthesis. The deltaleuD deltapanCD double auxotroph is fully attenuated in the SCID mouse model and highly immunogenic and protective in the extremely sensitive guinea pig tuberculosis model, reducing both bacterial burden and disease pathology.
我们开发了一种活的、完全减毒的结核分枝杆菌疫苗候选菌株,该菌株在亮氨酸和泛酸生物合成中具有两个独立的减毒营养缺陷型突变。ΔleuD ΔpanCD双营养缺陷型在SCID小鼠模型中完全减毒,在极其敏感的豚鼠结核病模型中具有高度免疫原性和保护性,可降低细菌载量和疾病病理。
