Outcomes
• You will be able to explain the difference between a viral and bacterial infection

Brainstorm
• With your partner jot down as many things as you know about bacteria and viruses
• You have 2 mins.!!

• Enclosed by a cell wall• Contains cytoplasm and
hereditary material of the cell
• Ribsomes are the only organelle found in the cytoplasm
Bacteria Virus
• DNA or RNA (retrovirus)
• Surrounded by protective protein coat (capsid)
• Genetic material carries information for multiplication
• Hijacks biochemical machinery of host cell to carry these processes out

• Infectious disease can be spread through:
1. contact with an infected person ex: Influenza (V) 2. contact with a contaminated object ex: Influenza (V) 3. contact with an infected animal ex: Lyme Disease (B): Bite from infected tick contact with an environmental source.

Cause disease by either damaging or killing cells
First attaches itself to a healthy cell and then injects its DNA or RNA into cell
Then replicates once inside infected cell
No Cure, just prevention with vaccine.
Vaccines: a substance introduced into the body to stimulate the production of chemicals that destroy specific viruses or bacteria..

Diseases Caused by Bacteria
Use antibiotics to cure bacterial infections
Antibiotics or a chemical that can kill bacteria without harming a person’s cell
Bacteria can develop a resistance to antibiotic and will no longer kill
This is what happens when you do not take medicine completely
AnthraxLyme
Disease LeprosyBacterial
MeningitisStrep ThroatTuberculosis

Virus vs. Bacteria
Bacteria and Viruses Comparison
Bacteria VirusNucleus No No, they have no cells
Reproduction Fission, conjugation & spore formation
Dependent on host cell machinery
Can cause disease? Yes Yes
StructuresDNA & RNA float in the cytoplasm, surrounded by cell membrane & wall
DNA or RNA enclosed within a protein coat (capsid)
Living Attributes Living organism Non-livingInfection Localized Systemic
Beneficial Some (photosynthesis, vitamin production, nitrogen fixation) Not beneficial
How treated? Antibiotics Antivirals slow & vaccines prevent
# of cells Unicellular Non-living — no cells
Systemic means it's in the blood stream and is spreading/has spread through
the body
Localized means the infection is
restricted to one small area
only. An infected cut or
ulcer is an example of this.

Hunting the Nightmare Bacteria
• http://www.pbs.org/wgbh/pages/frontline/hunting-the-nightmare-bacteria/
• Name the 3 diseases contracted• For each provide:– Characteristics of infection– Cure?– How was it contracted?
• Overall question to answer: What is the problem with antibiotics?
