Definition of Microbiology
Microbiology is basically the study of unicellular and microscopic
multicellular organisms. It is a life based understanding, and strongly
assists us in functions related to our natural lives. Subjects such as
birth, growth, aging, physical traits, can all be traced back to
microbiological reasoning; in this case, DNA. Below is a picture of
DNA, it's life bearing importance rivals any other microbiological
function of the human body.
Random House Dictionary classifies microbiology biology as a noun,
defining it as: 'the branch of biology dealing with the structure,
function, uses, and modes of existence of microscopic organisms'.
Mariam-Webster's Dictionary also defines it as: 'a branch of biology
dealing especially with microscopic forms of life (as bacteria,
protozoans, viruses, and fungi)'.
Below is a picture of an agar plate carrying a streak of
microorganisms. The agar plate can hold collective groupings of
thousands of tiny little creatures on it's flat surface.
Basically, it is a very simple classification with a very widely accepted general definition.
The field of microbiology is broken down into many different sub
disciplines, such as medical microbiology, cellular microbiology,
genetic microbiology, bacterial microbiology and many more, probably
too numerous to mention within this space. Even viruses such as the common cold are microbiological in nature.
Below is a picture of a particular type of bacteria. Bacteria, although
not unicellular, is a microscopic multicellular life form, ergo fits
under the classification of microbiological study.

understanding of what microbiology is, how we have learned of it, and
what it does and can do for humanity both now, and further down the
