噬菌体在细菌细胞之间移动DNA的能力使其成为细菌宿主遗传操作的有效工具。这里介绍的是一种诱导、恢复和使用 φBB-1( 伯氏疏螺旋体噬菌体)在莱姆病螺旋体的不同菌株之间转导异源 DNA 的方法。
该协议意义重大,因为它描述了剖析莱姆病病原体伯氏疏螺旋体分子生物学的另一个重要工具。该技术的主要优点是,通过使用噬菌体转导,它提供了一种在伯氏疏螺旋体中引入DNA的替代方法,而无需像电穿孔那样应用电脉冲。该方法可用于进一步了解伯氏疏螺旋体在其地方性动物病周期中持续存在并最终导致人类莱姆病的分子机制。
首先,将150微升适当的伯氏疏螺旋体克隆接种到15毫升BSK中,用于转导方案。然后,用适当浓度的抗生素或抗生素组合补充培养基,以选择和维持伯氏疏螺旋体克隆内的异源DNA,并将样品在33摄氏度下孵育。培养物长大后,将适当体积的培养物以6, 000 G离心10分钟。
