Studies of the spirochete Borrelia burgdorferi have been hindered by the scarcity of genetic tools that can be used in these bacteria. For the first time, a method has been developed by which heterologous DNA (DNA without a naturally occurring B. burgdorferi homolog) can be introduced into and persistently maintained by B. burgdorferi. This technique uses integration of circular DNA into the bacterial genome via a single-crossover event. The ability to transform B. burgdorferi with heterologous DNA will now permit a wide range of experiments on the biology of these bacteria and their involvement in the many facets of Lyme disease.
对伯氏疏螺旋体的研究一直受到可用于这些细菌的遗传工具稀缺的阻碍。首次开发出了一种方法,通过该方法可将异源DNA(没有天然存在的伯氏疏螺旋体同源物的DNA)导入伯氏疏螺旋体并使其持续维持。该技术利用环状DNA通过单交换事件整合到细菌基因组中。用异源DNA转化伯氏疏螺旋体的能力现在将允许对这些细菌的生物学特性及其在莱姆病诸多方面的作用进行广泛的实验。
