Microbiology is the study of microorganisms, which are living organisms that are too small to be seen with the naked eye. This field encompasses the study of bacteria, viruses, fungi, and protozoa, among other types of microorganisms. Microbiologists study the structure, function, and behavior of these organisms, as well as how they interact with their environment and other organisms. Microbiology has many applications, including in the fields of medicine, agriculture, environmental science, and biotechnology. It is a diverse and rapidly evolving field that plays a crucial role in understanding and combating diseases, developing new antibiotics and vaccines, and ensuring the safety of food and water supplies.
