BACTERIAA long time ago in a galaxy

far, far away…

There was Bacteria

It had two types

Eubacteria, and Archaebacteria

And it was interesting…

A Presentation by Trip Smith

And Mason Watson

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.

The Dead Sea

A Volcano

•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
