Module No.1, Lesson 1: Introduction to Microbiology
Preface
“Microbes, including bacteria, fungi, archaea, protists and viruses, are the
smallest creatures that ever lived. They are also the most abundant and
successful organisms on Earth, “outnumber[ing] the stars in the known universe
by more than 100 million times over.” They created the Earth’s oxygen-rich
atmosphere, and they make up half the weight of life on Earth. Together, let us
figure out who is there and what to call them”. Tim Mcnulty for The Hidden Half of Nature
What is microbiology?
Microbiology translates to “the study of small life,” where the small life
refers to microorganisms or microbes. Microorganisms are so tiny that they can
only be seen with the aid of microscopes. Although microorganisms are
widespread in nature and are beneficial to life, some can cause serious harm.
What is a microorganism?
Microorganisms or microbes are microscopic organisms that exist as
cellular microbes (or organisms) and the acellular microbes (or agents). Cellular
microbes can be either unicellular, where one cell is the entire organism, or
multicellular, where numerous number of cells can make up the entire organism.
Under this category we have the bacteria, the archaea, the fungi, and the
protists. In the acellular camp we have the viruses and other infectious agents,
such as prions and viroids which needs host cells in order to multiply.
A microorganism can either be pathogenic or non-pathogenic. Pathogenic
microorganisms can infect and cause diseases on human, plants or animals while
non- pathogenic microorganisms are beneficial to the host. In fact, a normal flora
is a population of microorganisms naturally present within a healthy body. It
could be on the skin surface, within natural body cavities, in the gastrointestinal
tract or reproductive tract.
In order to identify and classify microorganisms, you must first learn their
characteristics.
Characteristics of Microorganisms
1. Morphological characteristics: cell shape, size (μm), and structure, special
structures, cell arrangements, staining reactions and motility and flagellar
arrangements.
