家家是个微生物园?

如果你能数清楚你家中所有的细菌,你觉得能有多少种不同的种类?五十?几百?几千怎么样?千的前面要带个“几”。我的下一位来宾有一些志愿者,他们清扫了家里的一些表面:枕套,电视屏幕,马桶座圈要看一看什么东西或许生活在那里。这四十个家庭中所选择清扫的表面都是相同的。结果如何呢?几乎8,000种不同种类的细菌把它们的家安在了我们的家中。

去拿抗菌喷雾剂?唉呀,别这么着急。有这么多细菌是一件好事情——我的下一位来宾说,我们应该照顾我们的多样性的微生物园。

If you could count up all the bacteria in your house, how many different species do you think you could find? Fifty? A couple of hundred? How about thousands with an s at the end. My next guest have volunteers swept? surfaces in their homes: pillow case, the TV screen, the toilet seat to see what might be living there. And in each of the forty households the same spots were swept?. What was the result? Almost eight thousand different kinds of bacteria are making themselves at home.

Reaching for the antibacterial spray? Well, not so fast. Having all these bacteria is a good thing – my next guest says, we should be tending our diverse microbial gardens.

有一项来自底特律的研究显示,生活在有狗的家庭中的孕妇其脐带血中显示不容易携带我们与过敏相联系的抗体。还有显示表明与狗相伴成长起来的儿童不容易患喘息和哮喘。以上两例提示,可能所发生的情况是,在那些家庭中,那些儿童和胎儿暴露于更多种类的细菌中,在某种程度上使他们的免疫系统做好了准备,并使其免疫系统更正常地运行。

There is a study from Detroit that suggests that pregnant mothers who live in houses with the dog are less likely to show evidence in their umbilical cord blood of the kinds of antibodies we associate with allergies. It’s also been shown that the young children grown up with dogs are less likely to develop wheezing and asthma. So in both cases, been suggested that maybe what’s happening is that in those houses, those children and the fetus are being exposed to more kinds of bacteria, the sort of prime their immune system and make their immune system functioning more normally.
