Bacteria
• Bacteria are prokaryotes, simple
and less complex living organisms.
• The bacteria discussed in this unit
are organisms that are composed
from the kingdom Eubacteria,
domain Bacteria and the kingdom
Archaebacteria, domain Archaea.
Eukaryotes VS Prokaryotes
• Eukaryotes
1. Has a nucleus & other
organelles
2. Large ribosomes
3. Has a cytoskeleton
4. Divides through mitosis
or meiosis
5. Asexual or sexual
reproduction
6. DNA is linear
• Prokaryotes
1. No nucleus or other
organelles
2. Small ribosomes
3. No cytoskeleton
4. Divides through binary
fission
5. Asexual ONLY
6. DNA is circular
Bacteria VS Virus
• Similarities
1. Both are microscopic
2. Both can evolve to
pathogens
3. There are helpful and
harmful viruses and
bacteria
• Differences
1. Bacteria are much
LARGER than a virus
2. Bacteria are living,
viruses are non-living
3. Bacteria are treated
through antibiotics,
viruses through vaccine
Bacterial shapes
1. Bacillus: rod-shaped cell
2. Coccus: round, spherical shaped cell
3. Spirillum: spiral cell
small bacteria…
TROUBLE

1. Annotate each
paragraph 4 times

Good Bacteria 
Bacteria is known for causing us to feel sick, form diseases and
spoil food…so, what are the benefits of bacteria???
1. Food & Chemical Production: Many processed food are made by bacteria!
Example: Swiss cheese, pickles, olives, vinegar and sourdough bread.
Example: A bacterium clostridium produces acetone & butanol.
2. Mining & environmental use:
Powders containing petroleummetabolizing bacteria are used in the
clean up of oil spills, aiding in carbon
and nitrogen cycles
Bad Bacteria 
• Our bodies are a treasure chest of resources: proteins,
minerals, fats, carbs and vitamins.
We need and want these resources, but so does bacteria…
Competition for these resources can result in an illness
Escherichia coli and Salmonella: cause food
poisoning.
Helicobacter pylori cause gastritis and ulcers.
Neisseria gonorrhoeae causes the sexually
transmitted disease gonorrhea.
Neisseria meningitidis causes meningitis.
Staphylococcus aureus causes a variety of
infections in the body, including boils, cellulitis,
abscesses, wound infections, toxic shock
syndrome, pneumonia, and food poisoning
Streptococcal bacteria cause a variety of
infections in the body, including pneumonia,
meningitis, ear infections, and strep throat.
Good vs. Bad Bacteria Storyboard
• You are going to create a storyboard (comic strip) of the effects of good bacteria
AND bad bacteria on an organism (humans, animals, plants)
• Each comic will have 4 frames each, for a total of 8 frames for the assignment
Each frame should contain the following:
1. Draw your bacteria using one of the 3 shapes of bacteria
2. Draw a picture describing the role/job of the bacteria
3. Illustrate how the bacteria does its job showing the effects on the organism
4. Illustrate the end result of the bacteria once the job is complete

Agenda:
• Practice: Public Service Announcement
Homework:
• PSA due TODAY in class for 30 Points
(GRADEBOOK)
• GRADEBOOK CLOSES TUESDAY, 5/17/2016
Public Service Announcement
• Public service announcement is used to make the public
(people) aware of an issue, outbreak, etc.
• Each student will select a bacterial disease to create a
public service announcement poster.

Disease
Pathogen
Vector/Reservoir
Epidemiology
Anthrax
Bacillus anthracis
Animals, including
Bacterial infection that
can be transmitted through processed skins contact or ingested. Rare except in sporadic
outbreaks. May be fatal.
Chlamydia
Chlamydia trachomatis
Humans, STD
Urogenital infections with
possible spread to eyes and respiratory tract. Occurs worldwide; increasingly common over past
20 years.
Cholera
Vibrio cholerae
Human feces, plankton
Causes severe diarrhea
that can lead to death by dehydration; 50% peak mortality if the disease goes untreated. A
major killer in times of crowding and poor sanitation; over 100,000 died in Rwanda in 1994
during a cholera outbreak.
Lyme disease
Borrelia bergdorferi
Ticks, deer, small rodents
Spread through bite of
infected tick. Lesion followed by malaise, fever, fatigue, pain, stiff neck, and headache.
Typhus
Rickettsia typhi
Lice, rat fleas, humans
Historically a major
killer in times of crowding and poor sanitation; transmitted from human to human through the
bite of infected lice and fleas. Typhus has a peak untreated mortality rate of 70%.
