Microbiology is the study of tiny living organisms that are too small to be seen with the naked eye. This field includes various types of microorganisms, such as bacteria, viruses, fungi, and protozoa. Microbiologists explore how these organisms live, grow, and interact with their environments, which can be crucial for understanding health, disease, and ecosystems. Microbiology plays a vital role in many areas, including medicine, agriculture, and food production. For instance, bacteria can be beneficial in making yogurt and cheese, while some can cause illnesses. By studying these microorganisms, scientists can develop new treatments and improve food safety.
