Cultures of Mycobacterium tuberculosis grown under oxygen depletion conditions enter into a state of nonreplicating persistence that may reflect a physiologically latent state. When these cultures were harvested and injected intranasally into mice, no bacteria could be recovered from the lungs for about 3 weeks, but after that evidence of regrowth was observed. Preimmunization of mice with a panel of selected vaccine candidates slowed or prevented this event. This simple model has potential for identifying vaccines targeting latent tuberculosis.
在缺氧条件下培养的结核分枝杆菌进入一种非复制性持续状态,这可能反映了一种生理潜伏状态。当收获这些培养物并经鼻内注射到小鼠体内时,在大约3周内肺部未检测到细菌,但之后观察到有细菌再生长的迹象。用一组选定的候选疫苗对小鼠进行预免疫可减缓或阻止这一现象。这个简单的模型有潜力识别针对潜伏性结核病的疫苗。
