mi•cro•bi•ol•o•gyˌmaɪ kroʊ baɪˈɒl ə dʒi(n.)
the branch of biology dealing with microscopic organisms.
Origin of microbiology:
the branch of biology that studies microorganisms and their effects on humans
The branch of biology that deals with microorganisms, especially their effects on man and other living organisms.
Microbiology is the study of microscopic organisms, either unicellular, multicellular, or acellular. Microbiology includes the disciplines virology, mycology, parasitology, bacteriology, and so on. Eukaryotic microorganisms exhibit cell organelles and include fungi and protists, whereas prokaryotic organisms—which all are microorganisms—are conventionally classified as lacking organelles and include eubacteria and archaebacteria. Microbiologists traditionally relied on culture, staining, and microscopy. Apparently, however, only some 1% of the microorganisms present in some environments are culturable. Microbiologists often rely on extraction or detection of nucleic acid, either DNA or RNA sequences. Viruses are not always classified as organisms, as they have been identified either as very simple microorganisms or very complex molecules. Prions, never considered microorganisms, have been investigated by virologists, however, as the clinical effects traced to them were originally presumed due to chronic viral infections, and virologists took search—discovering "infectious proteins".
U.S. National Library of Medicine
The study of microorganisms such as fungi, bacteria, algae, archaea, and viruses.
