The study of small organisms ranging from one cell to few cells to no cells at all. It encompasses fields such as virology, bacteriology, protistology, & mycology.

Which of the following best describes the scope of microbiology?

Microorganisms, or microbes, are small organisms that are generally too small to be seen without a microscope. They are highly abundant and can be found almost everywhere on Earth, from boiling thermal hot springs to deep beneath the Antarctic ice. While the vast majority of this invisible world remains unexplored, microbiologists continue to discover new ways in which microbes interact with the environment and humans.

Microbes

Microbial culturing is a laboratory procedure where a biological sample is placed in special dishes to encourage the growth of microorganisms, such as bacteria or fungi. Because microorganisms require time to reproduce into sufficient quantities, it can take a while before they can be effectively detected and analyzed.

Microbial Culturing

As microbiology has developed, it has allowed the broader discipline of biology to grow and flourish in previously unimagined ways. Much of human knowledge concerning cells and their genetics is derived from an understanding of microbes, and many tools currently used to study cells originate from work with microorganisms.

Microbiology's Impact on Biology

While microbiology broadly encompasses the study of all microorganisms, microbiologists in practice typically specialize in one of several subfields. These major disciplines include bacteriology (bacteria), mycology (fungi), protozoology (protozoa), parasitology (helminths and other parasites), and virology (viruses). Immunology is also frequently included in microbiology because host-pathogen interactions are central to understanding infectious disease processes. Other areas of specialization include clinical, environmental, applied, and food microbiology.

Disciplines in microbiology

Microbiology studies and clinical practice must be guided by a core set of ethical principles to protect individuals and ensure scientific integrity. Key requirements include conducting studies with integrity, obtaining informed consent from participants, respecting patients' rights, maintaining accurate records, ensuring confidentiality, and communicating honestly. Additionally, all research procedures involving humans must be approved by an institutional review board, and protocols using animals must be cleared by an institutional animal care and use committee.
