Bacteria
Definition: Bacteria is plural for Bacterium. A bacterium is a microbe (a microscopic single cell
organism) that can be found virtually anywhere. They are in air, the soil, and water, and in and on plants
and animals.
Function: There are good and bad bacteria. They have useful functions like: making vitamins, breaking
down garbage, and even maintaining our atmosphere. The human mouth is home to more than 500
species of bacteria. The more we know about bacteria, the more we are able to figure out how to make
microbes work for us or stop dangerous ones from causing serious harm.
Appearance: A Bacterium consists of a single cell.

Microbacterium tuberculosis (Tuberculosis)
Streptococcus pneumoniae (Strep Throat, Meningitis, and Pneumonia)
Virus
Definition: Viruses are the simplest and tiniest of microbes. They can be as much as 10,000 times
smaller than Bacteria. Viruses consist of a small collection of genetic material (DNA or RNA) encased
in a protective coat called a capsid.
Function:
When viruses come into contact with the “host cells” (such as normal human cells), they trigger the cells
to engulf them and connect themselves so they can release their genetic material (DNA) into the cell.
Once inside a host cell, viruses take over its machinery to reproduce. Once this occurs, the virus then
overrides the host cell's normal functions with their own set of instructions which shut down the
production of the host cell’s proteins and direct the cell to produce viral proteins to make new viruses.
Some viruses insert their genetic material into the host cell's DNA, where they begin directing the
copying of their genes or simply lie asleep for years or a lifetime. Either way, the host cell does all the
actual work, the viruses simply provide the instructions.
