“冰渏人体”青海:鼠疫防控冰渏人体技术体系创新与应急能力提升研究获突破性进展

  中新冰渏人体网西宁12月2日电 (杜兆军冰渏人体 赵忠智 张添福)记者2日从青海省地方病预防控制所获悉,该所研究团队开展的《鼠疫防控技术体系创新与突发应急处置能力提升研究》,获得多项突破性进展。

  据中新网记者了解,《鼠疫防控技术体系创新与突发应急处置能力提升研究》由青海省地方病预防控制所张青雯、代瑞霞、马英科研团队完成,并入选全国卫生健康科技工作会议科技创新成果展。

  青海省地方病预防控制所副所长张青雯介绍,针对我国鼠疫防控中的技术难点,该研究首次证实田鼠型鼠疫菌可抑制宿主的固有和获得性免疫,首次提出该菌对人不致病可能与其在人细胞溶酶体中的生存能力下降有关,揭示了RLR信号通路是重要且具有负面作冰渏人体用的模式识别受体,丰富了鼠疫菌致病机制研究,从免疫学层面上为鼠疫防治提供了研究新思路。

  同时,该研究首次发现我国存在耐链霉素鼠疫菌株,世界范围内首次证实鼠疫菌的高水平链霉素耐药与鼠疫菌rpsL基因突变相关,并结合研究发现提出了替代抗生素和联合用药等耐药应对措施;首次全面研究了青藏高原鼠疫菌的遗传特征,分析高原鼠疫菌遗传多样性和基因分型特点,解析其基因组变异规律,并成功地应用于鼠疫疫情传染源的溯源,将菌株资源优势转化成监测预警、进化溯源及其他科学研究的重要资源,为鼠疫疫情溯源及机制研究提供科学依据。

  张青雯说,该研究首次将青藏高原宿主动物线粒体基因、鼠疫菌基因分型和人间鼠疫疫情进行相关性分析,发现早獭种群遗传多样性对鼠疫流行暴发有较强的影响;首次用遗传学证据证实了喜马拉雅旱獭亚种的存在,并利用多基因标记、无人机遥感和AI等新技术研究早獭谱系地理结构,推动了鼠疫监测工作的数字化、智能化和可视化。(完)
