家中的灰尘里藏有九千种细菌

A genetic analysis revealed that the average household had more than 2,000 species of fungi. The types of fungus found though depended on the home's location, suggesting these minute organisms are drifting in from outside.

一个基因分析表明,每户家庭平均有2000多种真菌。不过真菌的类型取决于这些家庭所在的位置,这表明这些微生物是从外面飘进来的。

The researchers also discovered an average 7,000 different types of bacteria per household. But the species varied according to whether men or women were the main residents or whether they lived with cats or dogs.

研究人员还发现,每户人家平均有7000多种不同的细菌。但细菌种类各不相同,细菌种类取决于主要居住者是男是女,或者是否与猫狗一起生活

Although the study was carried out in the US, the scientists say the findings are also relevant around the world.

尽管这项研究是在美国进行的,但是科学家们表示,这项研究同样对全世界也很有意义。
