(8.L.1.1 AND 8.L.1.2)

8.L.1.1 Summarize the basic characteristics of viruses, bacteria, fungi, and parasites relating to the spread, treatment and prevention of disease.

8.L.1.2 Explain the difference between epidemic and pandemic as it relates to the spread, treatment and prevention of disease.


Microbiology is the branch of science that deals with micro organisms.



Virus- A non-living pathogen That can change mutate. It infects host cell and replicates to cause illness and disease.


Bacteria- Single-celled prokaryotes that can cause disease. Multiply rapidly and can form colonies


Parasite- An organism that lives in or on another organism. Called a host cell taking nutrients an often harming it in the process.


Fungi- A single-celled or multi-celled organism that can decompose or absorb organic matter. Ex: mushrooms, yeast, or mold.

Outbreak, Epidemic, Pandemic


Outbreak- Occurrences of a disease greater than would otherwise be expected at a particular time and place.


Epidemic- An outbreak of a disease that effects many people in an area of a specific country or region.
The difference between Epidemic and Pandemic is that epidemic is in a specific are and pandemic is that it is all over the world.


Pandemic- An epidemic that spreads over a very large area or through out the entire world.



Vector- An organism typically an insect that transmits disease.


Pathogen- A virus, bacteria, fungi, parasite, or protozoa that can cause illness and infection


Protozoa- Diverse organisms that cannot be classified as animals, plants, or fungi.

EX- Amoebas and algae

Host cell

Host cell- a cell that a virus invades,takes over, and makes copies of its self.


Quarantine- A time or place of isolation in which people or animals that have been exposed to an infectious or contagious disease are placed.
