Diseases

Essential Question:How do microbes influence the

treatment/prevention of a disease?

Vocabulary

• Bacterial Disease Vaccine • Viral Disease Contamination• Resistance• Treatment• Antibiotics• Dose• Prevention

Concept

• How to treat/prevent diseases.

Bacterial Diseases

1. Rabies – transmitted through bite of infected animal.

2. Lyme disease – bull’s eye rash; tick bite.

Bacterial Diseases

3. Bacterial Meningitis – inflammation of nervous system.

4. Leprosy – skin lesions or blisters.

Viral Diseases1. AIDS/HIV – immune system

deficiency; more likely to get other infections.

2. Influenza – infection of nose, throat, lungs.

3. Common Cold – runny nose, sore throat, headache.

4. Chicken Pox – itchy blisters on skin.

Viral Diseases5. Polio – affects nerves; victims can be

paralyzed.

“Iron Lung” – Helps a person breathe.

Viral Diseases

6. Small Pox – infects blood vessels; causes severe rash and fever. Has been declared “eradicated” – wiped out.

7. Yellow Fever – fever that causes liver damage and jaundice, a yellow-ish skin color due to the liver damage.

Viral Diseases

8. Viral Meningitis – inflammation (swelling) of nervous system; rash; headaches.

Viral Diseases

9. West Nile – flu-like symptoms; mosquito carried illness.

10.Ebola – fever, rash, circulatory system infection, and organ failure.

Treatment

• A method to treat a patient once they are already sick.

• Viruses – only symptoms can be treated; immune system “fights” virus on its own.

Antibiotics

• Treatment for bacterial infections.• Antibiotics – kill bacteria cells.

Dose

• The amount of medicine a person takes based on age and weight.

Prevention

• Boosting a person’s immune system BEFORE contracting an illness, so the immune system can fight it off.

• Can be: vaccine, washing hands, sleep, exercise, etc.

Vaccine

• “Dead” or weakened form of a virus; injected to allow person’s immune system to fight it off on its own when it comes in contact with the virus.

Contamination

• When bacteria are present on unclean surfaces or food.

• Surfaces must be sanitized; food thoroughly cooked.

• Can lead to food poisoning / E.coli, salmonella.

Resistance

• Antibiotic resistance – when bacteria are not killed by antibiotics after several generations.

• Caused by overusing the same antibiotics.
