细菌无处不在。一提到它,大家首先想到的就是细菌会致病,会引起食物变质,人食用后会发生胃肠疾病。或许有人认为,凡是细菌都是有害的,只有“无菌状态”才是最洁净、最健康的,这些想法是错误的。
Bacteria are everywhere. Mention the first thing that comes to mind is that bacteria can cause illness and can cause food spoilage. Gastrointestinal problems can occur after human consumption. Some people may think that all bacteria are harmful, only the “sterile state” is the cleanest and most healthy, these ideas are wrong.
