Microbiology is the study (logy) of very small (micro) living (bio) things.
Microbiology is the study of microorganisms. These "bugs" include: bacteria (that's the Latin plural for bacterium); viruses (that's the non-Latin plural for virus - virii sounds weird, so I don't say it); and, fungi (that's the Latin plural for fungus - which by now you have guessed, or already knew, and may not be all that interested to know, anyway). Microbiology is actually made up of several sub-disciplines.
Microbiology, one of the fastest growing areas of science, is the study of organisms so small that they must be viewed with a microscope. These organisms are primarily bacteria, yeasts, molds, and viruses. Many of the most important scientific discoveries of recent years have been made by microbiologists: since 1910, one-third of the Nobel Prizes in medicine and physiology have been awarded to microbiologists. They are concerned with the welfare of humankind, concentrating not only on aspects of host-microbial interactions influencing disease and immunity, but also on ecological concerns impacting food production and the environment. There is a great demand for microbiologists. Graduates with a concentration in Microbiology find positions in the areas of medical, agricultural, food, industrial, or pharmaceutical microbiology, or microbial genetics or physiology. They may become teachers, science writers, technical librarians, or managers of scientific companies. Some of these professions require advanced degrees. The concentration in Microbiology is designed to furnish necessary experience in academic and practical skills to prepare graduates for immediate entry into the job market or for continuing graduate education in pure or applied biological sciences.
Microbiology is the branch of science dealing with microorganisms. It is one of the most relevant, dynamic and exciting disciplines in the biological sciences.
