Viruses and Bacteria
By: Jacob Arnett
Bacteria
• Bacteria is the plural word for bacterium.
• Bacteria are microorganisms.
• There are 3 types of bacteria: spherical, rod
shaped, and spiral.
• Spiral bacteria are known a spirillia, which
coils are usually very tight.
• Spherical bacteria are known as cocci, which
is round like a ball.
• The rod shaped bacteria are known as bacilli,
these are also curved and called vibrio.
Viruses
The Latin term virus means poison or toxin.
It consists of RNA and DNA surrounded by lipids and
proteins.
They cannot reproduce without a host cell.
The virus will inject a material into the host cell to take
over all it's functions.
The cell will eventually reproduce, but reproduces the
virus not its original reproductions.
Differences Between
Viruses and Bacteria
• Bacteria do not have to use a host cell to
reproduce.
• A virus is not a cell.
• Bacteria can be cured with antibiotics, while
virus have to be cured with vaccines.
What is Harmful About
Bacteria
• Bacteria can be harmful and can kill you, but
they are able to be fought off easier than
viruses.
• All bacteria can be killed though, and taken
care of.
What is Harmful About
Viruses
• Viruses are very harmful and can even kill
you.
• They are more sneaky and more sly than a
bacterium. They can hide and when your body
tries to fight it the virus is no longer found.
• There are some incurable viruses though, like
HIV's and aids
Cures for Bacteria
• The cure for bacterium are antibiotics
• They kill and prevent further bacterial
infections.
Cures for Viruses
• The only cure for viruses are vaccines.
• Vaccines are basically a watered down version
of the actual virus.
