在具体防控举措方面,该研究指出需强化卫生健康、环境保护和农牧业等相关部门的协调联动,加 快智能化监控设备和诊疗技术在牧区的普及应用。同时,有关部门应持续提升公众卫生意识,防范跨区 域传播风险,推广动物疫苗,并建立环境风险监测体系,形成多部门协同的防控合力,依托"全健康"理 念,实现科技创新与系统治理双轮驱动,推动青藏高原包虫病防控从传统模式转向更加主动的精准防控 模式。 包虫病是由棘球绦虫寄生人体引起的人畜共患病,由犬、狐等终末宿主传播给人类和牲畜。其中泡 型包虫病也被称为"虫癌",如未得到有效治疗,超过90%的患者会在诊断后10—15年内死亡。全球约 86%的泡型包虫病新发病例集中于我国青藏高原地区。 研究团队建议,未来在科学研究方面应加强早期诊断技术、基因组学和传播动力学研究,揭示寄生 虫的遗传多样性及传播机制。此外,研究还需结合生态气候与社会经济因素,构建大数据模型,为科学 制定防控策略提供依据和指导。远程医疗与健康教育体系建设也不可忽视,尤其在牧区等偏远地区,应 大力推广便携式诊断工具,并完善流动人群的健康管理。 此次研究提到多项包虫病防控的先进技术和方法。例如,游离DNA技术和人工智能辅助的超声影 ...

Core Viewpoint - The application of environmental DNA (eDNA) technology for monitoring the endangered crested ibis in China represents a significant breakthrough, providing a new method for precise and efficient monitoring of this species and potentially other endangered species [1][19]. Group 1: Environmental DNA Technology - The research team from the Shaanxi Provincial Environmental Monitoring Center has successfully implemented eDNA technology to monitor the crested ibis by collecting air samples to detect residual DNA, overcoming the limitations of traditional monitoring methods [1][12]. - The eDNA sampling process involves capturing air samples that may contain particles from the crested ibis, such as feces and feather fragments, allowing for non-invasive monitoring [3][5]. - The team has established a genetic database for the crested ibis by collecting environmental samples and natural shedding materials, which aids in the design of specific primers for targeted monitoring [5][8]. Group 2: Monitoring Process and Results - The monitoring process includes setting up sampling points in key areas such as breeding, foraging, and migratory stopovers, with a systematic approach to ensure representative and scientifically valid samples [12][14]. - The team has successfully detected crested ibis DNA from air samples at 21 out of 22 sampling points, indicating the effectiveness of air as a monitoring medium compared to water and soil [14][15]. - The concentration of crested ibis DNA detected in air samples was approximately 37 DNA sequences per microliter, significantly higher than in soil and water samples, highlighting the advantages of air sampling for this species [14][15]. Group 3: Future Implications and Applications - The integration of eDNA technology into the monitoring framework for the crested ibis is expected to enhance the understanding of its population dynamics and distribution, supporting conservation efforts [19][21]. - This innovative approach not only benefits the crested ibis but also sets a precedent for the monitoring of other endangered species, contributing to broader conservation strategies [21]. - The collaboration of various monitoring methods, including traditional techniques and GPS tracking, is emphasized as essential for achieving comprehensive and effective monitoring of the crested ibis population [20][21].
