世界多地水样检出潜在抗菌素耐药基因
Ke Ji Ri Bao· 2025-12-23 02:15
抗菌素耐药性并非凭空产生。细菌天然携带一些使其对抗生素具有抵抗力的基因,这些基因广泛存 在于土壤、水体乃至人体微生物群中。然而,人类对抗生素的过度使用以及其他环境压力因素,加速了 这些耐药基因的扩散和演化,使其成为全球健康的重大挑战。 研究团队此次特别比较了两类耐药基因的地理分布:一类是已经激活并可在细菌之间传播的"获得 性耐药基因",另一类则是尚未激活、但具备耐药潜力的"潜在耐药基因"。结果发现,潜在耐药基因的 分布明显更为广泛。 一个国际研究团队对来自111个国家、351个城市的1240份废水样本进行了检测和系统分析,发现细 菌中潜在的抗菌素耐药基因(AMR)在全球各大洲普遍存在。相关成果发表于近期《自然·通讯》杂 志。 这项由丹麦技术大学国家食品研究所牵头的研究表明,尽管目前这些基因尚未构成重大公共卫生威 胁,但其中一部分未来可能演变为真正的风险。团队因此呼吁扩大对废水中抗菌素耐药性的监测范围, 将潜在耐药基因纳入常规检测体系。 研究确认,撒哈拉以南非洲、南亚以及中东和北非地区的获得性耐药基因丰度显著高于世界其他地 区,这与以往多项研究的结论一致。值得注意的是,在全球大部分区域,潜在耐药基因的数量都超过 ...
