一项研究发现,感染疟疾的宿主变得更吸引蚊子。研究论文于6月30日发表在《美国国家科学院院刊》(PNAS)上。瑞士联邦理工学院的马克麦斯切尔(Mark C.Mescher)和其同事利用疟疾感染的小鼠模型研究了疟疾感染与体味变化之间的关系。当小鼠感染了啮齿类疟原虫(Plasmodium chabaudii)后,研究者将小鼠放在抽风箱内。结果发现,蚊子对那些被感染的小鼠更加情有独钟,特别是在感染后的第10-20天。此时也恰好是小鼠血液中疟原虫配子细胞数量最大、传染性最强的时候。 One study found that hosts infected with malaria became more attracted to mosquitoes. The research paper was published on June 30 in the Proceedings of the National Academy of Sciences (PNAS). Mark C. Mescher of the Swiss Federal Institute of Technology and her colleagues used the mouse model of malaria infection to study the relationship between malaria infection and changes in body odor. When the mice were infected with Plasmodium chabaudii, the researchers placed the mice in a suction box. The results showed that mosquitoes were more interested in those infected mice, especially on days 10-20 after infection. This time also happens to be the largest number of malaria gametes in mice blood when the most contagious time.
