登革热是传播最广泛的媒介传播传染病之一。登革热的主要传播媒介是埃及伊蚊。天哪。埃及伊蚊流行于热带和亚热带,并与其非洲本土范围以外的人类栖息地密切相关。虽然美国东南部的登革热正在重新出现,但在2013年夏天之前,加利福尼亚州从未报告过繁殖种群。使用12个高度可变的微卫星基因座和参考种群数据库,我们已经确定加州引进的可能来源是美国东南部,排除了来自国外、来自地理位置较近的亚利桑那州或墨西哥北部种群的引入,或研究实验室意外释放的可能性。确定新引入的人类疾病侵袭性媒介来源的能力在很大程度上依赖于参考人群小组的可用性。我们的工作证明了生成广泛的人类疾病病媒遗传指纹参考数据库的重要性,以帮助公共卫生努力防止病媒传播疾病的引入和传播。登革热是一种媒介传播的疾病,近几十年来频率和严重程度急剧增加,影响到世界一半以上的人口。登革热的主要媒介是埃及伊蚊。2013年夏天,加州首次报告了这种蚊子的繁殖种群,这些种群的来源尚不清楚。我们对Ae进行了基因分型。并将它们的遗传组成和多样性与来自亚洲和美洲的参考种群以及实验室菌株进行比较,以确定此次引入的来源。我们认为美国东南部是加利福尼亚Ae最有可能的发源地。埃及伊蚊。这些信息将有助于设计遏制、控制和消除战略,以防止该州建立永久的繁殖媒介种群。注意,在跟踪新的疾病媒介引入的来源方面所达到的分辨率与参考数据集的完整性成正比。我们的分析被推迟了,以收集有关加利福尼亚州附近地区的进一步数据,否则将在一周内完成。这项工作强调了在危害公共健康的入侵发生之前建立人类疾病媒介基因型别的扩展数据集的重要性。
Dengue fever is among the most widespread vector-borne infectious diseases. The primary vector of dengue is the Aedes aegypti mosquito. Ae. aegypti is prevalent in the tropics and sub-tropics and is closely associated with human habitats outside its native range of Africa. While long established in the southeastern United States of America where dengue is re-emerging, breeding populations have never been reported from California until the summer of 2013. Using 12 highly variable microsatellite loci and a database of reference populations, we have determined that the likely source of the California introduction is the southeastern United States, ruling out introductions from abroad, from the geographically closer Arizona or northern Mexico populations, or an accidental release from a research laboratory. The power to identify the origin of new introductions of invasive vectors of human disease relies heavily on the availability of a panel of reference populations. Our work demonstrates the importance of generating extensive reference databases of genetically fingerprinted human-disease vector populations to aid public health efforts to prevent the introduction and spread of vector-borne diseases. Dengue fever is a vector-borne disease that has dramatically increased in frequency and severity in recent decades, affecting over half of the world's population. The primary vector of dengue is Aedes aegypti. Breeding populations of this mosquito were reported for the first time in California in summer 2013, and the origin of these populations was unknown. We genotyped Ae. aegypti from California and compared their genetic composition and diversity against reference populations from Asia and the Americas, and with laboratory strains, to identify the source of this introduction. We identified the southeastern United States of America as the likeliest origin of California Ae. aegypti. This information will aid the design of containment, control, and elimination strategies to prevent the establishment of a permanent breeding vector population in the state. Note that the resolution achieved in tracking the origin of new disease-vector introductions is proportional to the completeness of the reference dataset. Our analysis was delayed to gather further data on regions close to California and would otherwise have been completed within a week. This work highlights the importance of having an extended dataset of human disease-vector genotypes in place prior to the occurrence of invasions that compromise public health.
