成年人体内共有细胞约100万亿个,可是你知道我们体内的细菌有多少个吗?1000万亿!足足是人体细胞数量的10倍。过去科学家估算人体细菌种类的方法是从肠道中提取细菌,然后在培养皿上培养,待菌落长出后,再进行计数。可是这样做忽略了无法在
There are about 100 trillion cells in adults, but how many bacteria do we know in our body? 1000 trillion! A full 10 times the number of human cells. In the past, scientists estimated the type of bacteria in the human body by extracting the bacteria from the intestine and culturing them on a petri dish until the number of colonies grew. But ignore this can not be done
