Abstract: Malaria, which is transmitted primarily by bites of female Anopheles mosquitoes, is a mosquito⁃borne infectious disease that poses a serious threat to human health. Host body odor is a key factor to attract Anopheles mosquitoes. Upon Plasmodium infection, host body odors change, leading to increased attractiveness to female Anopheles mosquitoes; however, the underlying mechanisms remain clear. A recent study reported remarkable changes of skin flora and volatile substances in mice following Plasmodium infections, and ethylbenzene was found to increase host attractiveness to mosquitoes, which provides new insights into development of novel malaria control strategies.

摘要： 疟疾主要通过雌性按蚊叮咬宿主传播，是一种严重危害人类健康的蚊媒传染病。宿主气味是吸引按蚊的关键因素之一。宿主感染疟原虫后，气味发生变化且对雌性按蚊吸引力增强，但其机制尚不清楚。近期一项研究发现，小鼠感染疟原虫后皮肤菌群和挥发性物质均发生显著变化，且证实乙苯类化合物可以增强宿主对蚊虫的吸引力，该研究为开发新型疟疾防控策略提供了新思路。
