12/1 Objectives
Compare the structures, functions, and cycles of viruses to those of prokaryotic and eukaryotic cells.
Describe the role of viruses in causing diseases and conditions
(example; AIDS, common colds, smallpox, influenza, warts).
The infamous “Tree Disease”
Epidermodysplasia verruciformis A form of the Human Papilloma Virus
(HPV)
Key Point #1
Key Point #: Pathogen An organism that causes disease
Bacteria
Virus
Fungi
Key Point #2: Bacteria
• P________• S________
rokaryotic
ingle-celled
Important bacterial infections
Disease Effect on the bodyLyme disease Bull’s eye rash on
site of a tick bite, fever, fatigue, headache
Tetanus Lockjaw, stiffness in neck, difficulty swallowing
Tuberculosis Fatigue, weight lossStrep throat Fever, sore throat,
headache, fatigue
Key Point #3: Prevention
1. ___________ _________2. Disinfection3. Food storage 4. Sterilization
WASH HANDS
Key Point #4: Treatment
___________block the growth and reproduction of bacteria
Examples: Penicillin and tetracycline
ANTIBIOTICS
Key Point #5: Viruses
1.Not ______2.Made of a protein coat and
genetic material ( )3.Invade living cells to reproduce
LIVING
DNA
Key Point #6: Virus Life Cycle
Lytic cycle-Invades the host cell and kills it IMMEDIATELY.
Lysogenic cycle-Invades the host. Uses the cells DNA. Lives in the cell for awhile before killing it.
Important viral infections
Disease Effect on the bodyCommon cold
Sneezing, sore throat, fever, headache, muscle aches
Influenza (the flu)
Body aches, fever, sore throat, nasal congestions
Hepatitis B Jaundice, fatigue, abdominal pain, nausea, vomiting
West Nile Virus
Fever, headache, body ache
Key Point #7: Prevention
1._____________2.Wash hands 3.Avoiding contact with sick
people
VACCINES
Key Point #8: Treatment
• It is very difficult to treat viral diseases. Since viruses are not alive, you CAN’T kill them with antibiotics.
• There are some important antiviral drugs that make it better to live with a virus, BUT they cannot kill the virus.
• Antiviral drugs and the immune system killing the virus.
HIV/AIDS
Human Immunodeficiency Virus HIV is a virus that attacks the body’s immune
system and prevents it from fighting off other diseases.
HIV is transmitted through unprotected sex, child birth, breast feeding, and sharing needles.
Symptoms of HIV include rapid weight loss, fever, tiredness, flaky skin and heavy night sweats.
HIV is diagnosed by a simple blood test. HIV is treated with antiviral drugs. There is no
cure.
HIV/AIDS
Acquired Deficiency Syndrome HIV will progress to AIDS if left untreated AIDS is the final stage of HIV The body is no longer able to defend
itself AIDS victims are more likely to die from
the Flu of Pneumonia Why?
Unless the course of the epidemic changes, at some point in their lifetime, an estimated 1 in 16 black men and 1 in 32 black women
will be diagnosed with HIV.
How we might be tested on this…
1. Which of the following is TRUE about the prevention/treatment of HIV?
A) There is an HIV vaccine that makes you immune to the virus
B) Although drugs can prolong an infected person’s life, they are not always effective and come with many side effects
C) There is a cure for HIV, but is very expensive; only rich people can afford it
D) Most people recover from HIV on their own within two years
How we might be tested on this…
Disease Treatment Bacteria or Virus
Food poisoning Antibiotics, rest, fluids
HPV No cure. Annual pap-smear exams are recommended for women in order to prevent against cancer
Streptococcus Penicillin and rest
Common cold Take medicine such as Nyquil to treat symptoms (coughing, sneezing, Etc.) Nothing will cure it though

2. How are diabetes and HIV/AIDS different from each other?
A) HIV/AIDS is potentially lethal, while diabetes is not
B) HIV/AIDS is infectious and spread by certain types of human contact, while diabetes is not infectious
C) A person’s risk of developing HIV/AIDS is affected by their behavior, while diabetes occurs randomly
D) Diabetes can be effectively treated with medication, while HIV/AIDS cannot
How we might be tested on this…
3. Hepatitis B is a contagious disease that damages the liver. It can last a few weeks or can be a serious lifelong illness. It spreads through direct contact with bodily fluids from an infected person. An antigen test must be used to determine whether a person has active hepatitis B, because examining blood under a microscope will not show anything. This evidence shows that the cause of hepatitis B is: A) A virus B) A vitamin deficiency C) A genetic disorder D) A reaction to excess alcohol
