通過感染小鼠的貓恐懼永遠刪除
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。
壹項研究用老鼠證明,壹個臨時的感染可以危險和永久地改變了嚙齒動物的態度與對我們理解貓——的全面影響人類傳染性疾病。Wayt吉布斯報告。
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.
壹個糟糕的感染可以讓妳發狂的。但通常頭腦清除壹旦病菌都消失了。通常。不是所以當研究人員最近剛地弓形蟲小鼠註射。這種寄生原生動物只會在腸道的多情的壹只貓。由此產生的受精卵最終垃圾盒。他們面臨的挑戰是要長大,回來在壹個貓。解決方案:被吃掉的老鼠被貓吃了。
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.
遭到驅逐的雞蛋等到他們成為壹頓飯對於壹個鼠標。這些寄生蟲然後搬到老鼠的大腦。在那裏他們停止的老鼠害怕貓尿的味道。激動的鼠標方法毛茸茸的,瞧,寄生蟲會回家。
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.
在以往的試驗中,老鼠幾乎總是死於這種感染。本研究采用弱株弓形蟲和老鼠恢復但他們住貓的氣味。
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."
這壹個可以治愈的感染可以引起永久性行為變化是令人擔憂的,因為同樣的寄生蟲感染僅在美國就有6000萬人。大多數情況下無癥狀。但是壹些證據鏈接慢性感染,精神分裂癥和壹群其他精神疾病已知旨在為“貓夫人綜合癥”。
