一项国际研究发现,胆结石的形成与特定细菌的基因有关。研究人员认为,这一发现有助于开发胆结石治疗新方法,降低胆结石手术的必要性。

此前科学界已经发现克雷伯氏菌等细菌与胆结石的形成存在关联,但尚不清楚这些细菌在人类胆囊中生存并致病的机制。

澳大利亚柯廷大学研究人员与国际同行一起,在新一期英国《科学报告》杂志上报告了新发现。他们将细菌基因组和胆固醇结合起来分析,详细研究了人类胆结石的细菌构成和基因作用。

新研究确认了多种与胆结石有关的细菌基因,这些基因能帮助克雷伯氏菌等细菌在表面形成一层保护性的生物膜。这种生物膜不仅让细菌能抵御抗生素等药物,有机会在胆囊中生存下来,还能起到“胶水”一样的作用,使细菌不断积聚,这可能是胆结石形成的关键因素。

研究论文的主要作者、柯廷大学研究人员叙雷亚·柯塞说,新研究有助于了解胆囊中细菌生存和导致胆结石产生的机制,并据此进一步开发出除手术以外的疗法,减轻患者痛苦。
