Problem description:
The influence of microorganism on human health and life? Thank you!
Analysis:
There are Escherichia coli in our digestive tract, which can help us digest. There are many kinds of microorganisms, some of which are harmful to human body, such as tetanus Bacillus and fungi that cause colds. Some of them are mutually beneficial to human beings, such as Escherichia coli I mentioned just now, and some are useful to human beings, but I forget which ones! Microorganisms include all kinds of fungi, cocci, bacilli and bacteria ... Many mushrooms we usually eat are fungi. Coccidae are not in contact with each other in general life, and bacteria are everywhere around us. Because human beings have an immune system, they are not so vulnerable. In fact, there are many secondary metabolites of microorganisms that can be provided to humans as therapeutic drugs, such as penicillin and erythromycin. I haven't seen biology for half a year, and now I only remember these. I hope I can help you, thank you!
