英语阅读如何对付家里数以千计的细菌

浏览量: 发布时间:2018-03-01 14:49 点击在线免费咨询

遗传分析显示,平均每户有2000多种真菌。真菌的种类取决于家的位置,表明这些微小的有机体是从外面漂流出来的。
 
研究人员还发现,平均每个家庭有7000种不同类型的细菌。但这种物种因是否以男性或女性为主要居民或是否与猫或狗生活而有所不同。
 
尽管这项研究是在美国进行的,科学家们说这项发现在全世界也有关联。

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