《科技日报》电,据最新一期《自然·通信》杂志报道,美国研究人员发现了细菌在受压时自行关闭并进入维持状态的一种机制。这种控制机制有助细胞在紧急情况下迅速转移资源。此项新发现将有助于开发出针对结核病等疾病的新抗生素。许多细菌包括引起结核病的菌株,使用这种策略进入休眠状态,从而使其在缺乏氧气或营养的恶劣环境中继续生存下去。对于肺结核来说,在菌株最终“重新苏醒”并再次引起疾病之前,肺部感染可持续数年。
According to the latest issue of the journal Nature and Communications, U.S. researchers found a mechanism by which bacteria shut themselves down and into a state of sustainment when pressed. This control mechanism helps cells to quickly divert resources in emergency situations. This new discovery will help develop new antibiotics for diseases such as tuberculosis. Many bacteria, including those that cause tuberculosis, use this strategy to put them to sleep, allowing them to survive in harsh environments that lack oxygen or nutrients. For tuberculosis, lung infections can last for years before the strain eventually “regains consciousness” and causes the disease again.
