OCTOBER 18TH 2011

Today in class we watched a video and filled out a sheet that was aimed at inhancing our understanding of bacteria.

The work sheet went over the biological weapon botualism which was created by bacteria.

TO YOUR LEFT IS THE BOTULISM VIRUS

The video also discussed that bacteria can live in the harshest environments including hot spings, ocean vents and caves.

This picture above shows bacteria that has entered and found its way in a hot spring at Yellowstone National Park.

The video also went over where bacteria can be found in our bodies and how they are benficial to us humans.

Bacteria is found on our mouths and is on your mouth as you are reading this.

The picture above reveals a portion of someones tongue and zoomed in on it and found bacteria. The bacteria on our

tounges help us digest our food .

The video brought up an interesting topic. It stated that sourdough bread gets its flavor from bacteria from the mother

dough.

The video also discussed how streptococcus bacteria can infect many different areas in our

bodies and feeds on the tissue within the area its infecting.

This is streptoccoccus growing on the enamel of a tooth.

We also learned that Alexander Flemming accidently discovered a mold that killed bacteria and

later isolated the mold and created penicillin.

This is a penicillin pill ment to be taken orally.

Antibiotics are active against a diseases.

One of the main points that i got out of this movie was how traveling can affect the spreading of

bacterial infections. I learned that especially international travelers are constantly bringing in

new bacteria from the where they came from and are immune to the bacteria that already exist in

the place that they are visiting.
