653. 牙病简史:龋齿的兴衰与终结
from 知为谁 · host 知为谁
这篇文章探讨了龋齿(蛀牙)的演变历史、生物学成因以及潜在的生物技术解决方案。作者指出,导致蛀牙的变异链球菌通常在婴儿期由母亲传播,这种细菌通过代谢糖分产生乳酸,从而腐蚀牙釉质。研究发现,人类自农业革命以来,由于饮食中碳水化合物增加,牙齿健康状况显著恶化。为了应对这一持久的公共卫生挑战,科学家研发出一种名为 BCS3-L1 的转基因细菌菌株,它能通过竞争性定植取代致病菌,且不产生酸性物质。目前,这种“活体疫苗”已通过商业化途径向公众提供,有望成为彻底消除人类龋齿负担的关键工具。内容来源:https://www.cremieux.xyz/p/the-rise-and-impending-fall-of-the
