Medical News Today: What is the difference between Gram-positive and Gram-negative bacteria?
Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...

microbiology, study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria, archaea, algae, fungi, protozoa, and viruses.
Scientific microbiology developed in the 19th century through the work of Louis Pasteur and in medical microbiology Robert Koch. Avicenna postulated the existence of microorganisms. The existence of microorganisms was hypothesized for many centuries before their actual discovery.
Welcome to the wonderful world of microbiology! Yay! So. What is microbiology? If we break the word down it translates to “the study of small life,” where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they?
Microbiology is the study of microbes. Microbes, which are also called micro-organisms, are a group of organisms that are too small to be seen with the naked eye.
