BACTERIA
A long time ago in a galaxy
far, far away…
There was Bacteria
It had two types
Eubacteria, and
Archaebacteria
And it was interesting…
Introduction
• Two forms of Prokaryote
– Archaebacteria
– Eubacteria
• The oldest prokaryote
fossils date from 3.5
Billion years ago.
• All prokaryotes lack
distinct nuclei bound by
membranes.
• Archaebacteria can go
without oxygen, and often
live in inhospitable
environments.
• Although both Eubacteria
and Archaebacteria arose
from the same ancestor
billions of years ago, they
bear few common traits
today.
•Places Archaebacteria
have been known to
live are marshes, lake
sediments, digestive
tracts of mammals,
sewage, places of high
salt concentration (such
as the dead sea), and
areas of extreme heat.

Structure
• Unicellular
• Archaebacteria is more similar to
Eukaryotic Cells
• Cell Wall
• “Bacteria live in hypotonic environments”
Major Phyla & Species
• Few Hundred Species of Archaebacteria.
• More than 10,000 Species of Eubacteria

Cyanobacteria – Photosynthetic Autotroph
Mycoplasma pneumoniae – Pneumonia
Bordetella pertussis – Whooping Cough
Bacillus anthracis – Anthrax
Pasteurella pestis – The Bubonic Plague
Vibrio cholerae – Cholera
• Bacteria causes many extremely deadly
diseases.
BACTERIA SPECIES CASE
STUDY:
THE BUBONIC PLAGUE
Pasteurella Pestis
• Pastuerella Pestis is the species of Eubacteria that
caused the Bubonic Plague.
• Known as the black death, the Bubonic plague killed
millions in Europe during the 1300’s.
• The plague was introduced to Europe from China on an
Italian merchant ship in October 1347.
• By August the plague had spread to England, where the
natives called it “The Black Death.”
• In 1352, five years later, the population of Europe had
decreased from 75 million to 50 million.
• The Plague was never fully eradicated, and showed up
in serious epidemics until the 1600’s. It still exists today,
being contracted by roughly 2,000 people per year.

Feeding/Obtain Energy
• Eubacteria
– Feed from organic molecules and living
organisms
• Photosynthetic Autotroph
– Carries out Photosynthesis
• Chemosynthetic Autotroph
– “makes organic molecules”
– Breaks down inorganic compunds
Reproduction
• Asexual
• Binary Fission
– Copies chromosome
– Copy and original join
to membrane
– Separate
– Divide into two
“genetically identical”
cells
• Sexual
• Conjugation
– Transferring part or all
of chromosome over
pilus
