据新华社电,美国科学家近期通过猴子实验发现,感染寨卡病毒会刺激免疫系统以预防今后二次感染,但如果是在孕期被感染,寨卡病毒留存动物体内的时间会变得相当长。这项研究由美国威斯康星-麦迪逊大学的病理学教授戴维·奥康纳主导,已发表在最新一期英国《自然·通讯》期刊上。研究团队让一些恒河猴感染了2015年首次出现于南美洲的一种寨卡病毒。研究发现,虽然雄猴和未怀孕的雌猴在被感 According to Xinhua News Agency, U.S. scientists recently found through experiments with monkeys that infection with Zika virus could stimulate the immune system to prevent future secondary infections. However, if it is infected during pregnancy, the time it takes for the Zika virus to remain in the animal body will become quite long. The study, led by David O’Connor, a professor of pathology at the University of Wisconsin-Madison, has been published in the latest issue of the journal Nature in the World. The research team had some rhesus monkeys infected with a Zika virus that first appeared in South America in 2015. The study found that while both male and non-pregnant females are feeling
