1. Bacteria

2. Unit 5 - Viruses and Bacteria (Ch. 18)
Identify the major components of a Bacterium and Viruses
List the two major stages / life cycles of Viruses
Define Vaccines
Identify the three types of groupings and shapes of bacteria
List at least 5 different types of bacteria and or viral infections that can affect the body

3. SWBAT Scale
4: Same as a 3.0 but I can make inferences & application to the SWBAT’s
3: I COMPLETELY understand all parts of the SWBAT
2: I understand MOST of the SWBAT’s with teacher help
1: I understand a little of the SWBAT’s but need teacher help
0: I do NOT understand any part of the SWBAT’s and need help!

5. Two Kingdoms of Bacteria
Archaebacteria – the extremists
No-oxygen environments – makes methane gas
Marshes & lake sediments
Digestive tracts of animals
Sewage treatment plants – help break down sewage
High salt environments – Utah’s great salt lake and the Dead Sea
Hot waters of sulfur springs and cracks deep in the ocean floor.

6. Eubacteria Heterotrophs – get food from other organisms
Photosynthetic Autotrophs – Make their own food - photosynthesis
Chemosynthetic Autotrophs – Convert chemicals from atmosphere and soil into food

7. Bacterial Structure?
Capsule – sticky layer outside the cell wall (not all have this)
Cell wall – supports and protects
Plasma membrane – regulates what enters and leaves the bacterium
Plasmid –single circular DNA chromosome (NOT A NUCLEUS!!!)

8. Shapes:
Bacillus Coccus Spirillium
(Rod-shaped) (spherical) (spiral)

9. GROUPINGS
DIPLO
(TWO)
STREP
(CHAIN)
STAPH
(CLUSTER)

10. Gram Stain
Gram + Bacteria: turn purple (killed by antibiotic penicillin-attacks the cell wall)
–Ex. Strep throat
Gram – Bacteria: turn pink (killed by antibiotic tetracycline-doesn’t attack the cell wall)
- E.Coli
Antibiotics are drugs used to fight bacterial disease

11. Importance of Bacteria
They change “FIX” NITROGEN from the air so organisms can use it
Recycle nutrients (oxygen)
Food: swiss cheese, pickles, yogurt, vinegar, sauerkraut
E. Coli live in our intestines and help digest food
Some antibiotics are made by bacteria

12. Bacteria can cause disease
Strep throat
Tuberculosis
Tetanus
Lyme Disease
Dental cavities
Diphtheria – from contaminated water
The Bubonic Plague – transmitted from fleas
STDs such as chlamydia, gonorrhea, syphilis
Food Poisoning (E.Coli)
