Passing Infection Removes Mice's Feline Fear Forever
通过感染小鼠的猫恐惧永远删除
A mouse study finds that a temporary infection can dangerously and permanently change the rodent's attitude toward cats--with implications for understanding the full effects of human infectious disease. Wayt Gibbs reports。
一项研究用老鼠证明,一个临时的感染可以危险和永久地改变了啮齿动物的态度与对我们理解猫——的全面影响人类传染性疾病。Wayt吉布斯报告。
A bad infection can make you delirious. But usually the mind clears once the germs are gone. Usually. Not so when researchers recently injected mice with Toxoplasma gondii. This parasitic protozoan only gets amorous inside the gut of a cat. The resulting fertilized eggs wind up in a litter box. Their challenge is to grow up and get back inside a feline. The solution: get eaten by a mouse that gets eaten by a cat.
一个糟糕的感染可以让你发狂的。但通常头脑清除一旦病菌都消失了。通常。不是所以当研究人员最近刚地弓形虫小鼠注射。这种寄生原生动物只会在肠道的多情的一只猫。由此产生的受精卵最终垃圾盒。他们面临的挑战是要长大,回来在一个猫。解决方案:被吃掉的老鼠被猫吃了。
The expelled eggs wait until they become a meal for a mouse. The parasites then move to the mouse’s brain. Where they stop the rodent from fearing the smell of cat urine. The delirious mouse approaches Fluffy and, voila, the parasite finds its way home.
遭到驱逐的鸡蛋等到他们成为一顿饭对于一个鼠标。这些寄生虫然后搬到老鼠的大脑。在那里他们停止的老鼠害怕猫尿的味道。激动的鼠标方法毛茸茸的,瞧,寄生虫会回家。
In past trials, mice almost always died of this kind of infection. This study used weaker strains of Toxo and the mice recovered—but they stayed blasé about the cat smell.
在以往的试验中,老鼠几乎总是死于这种感染。本研究采用弱株弓形虫和老鼠恢复但他们住猫的气味。
That a curable infection can cause permanent behavior changes is worrisome because this same parasite infects 60 million people in the U.S. alone. Most cases produce no symptoms. But some evidence links chronic infection to schizophrenia and a cluster of other mental illnesses—known unscientifically as “crazy cat lady syndrome."
这一个可以治愈的感染可以引起永久性行为变化是令人担忧的,因为同样的寄生虫感染仅在美国就有6000万人。大多数情况下无症状。但是一些证据链接慢性感染,精神分裂症和一群其他精神疾病已知旨在为“猫夫人综合症”。
