Infectious Disease Ch 40 Sec 1 pg 1031 Germ Theory Virus 1. Fungi Bacteria Pathogen Disease Protist Worm Koch Postulates Any change, other than injury that disrupts the normal functions of the body (disrupted homeostasis) p1031 ________________________ 2. A disease causing agent is referred to as a _____________________ which cause “infectious disease”. 3. The idea that diseases were not caused by “black magic” rather by some infectious agent is known as _____________________________ 4. The idea that a pathogen should always be found in the body of a sick organism is one of the 4 principals in p1032 ______________________________ 5. A tiny particle that takes over the cellular machinery of it’s host p1033 ________________________ 6. Most of these are harmless but some break down tissue or releasing toxins p1033 __________________ 7. Plasmodium (malaria) and Trypanosoma (African sleeping sickness) are both caused by p1033 ___________ 8. Schistosoma, tape and hook are all examples of these that may feed in our bodies p1033 ______________ 9. Tinea which causes ringworm, jock itch and athlete’s foot are all examples of p1033 _________________ Give an example of a disease caused by the following – Not in book: 1. Genetic: ____________________________________________________________________ 2. Pathogenic: __________________________________________________________________ 3. Environmental Exposure:__________________________________________________________ Symptoms: a specific condition in the body that indicates the body is not working properly – not in book Examples: 1. __________________________ 4. _____________________________ 2. __________________________ 5. _____________________________ 3. __________________________ 6. _____________________________ Pathogen: An infectious agent that may cause a disease – List From Memory – don’t forget – Mad Cow Examples: 1. _______________________________ 4. _______________________________ 2. _______________________________ 5. _______________________________ 3. _______________________________ 6. _______________________________ Blood Borne Food borne Fecal Oral Vector STI Airborne Mode of Transmission How a disease is spread from one person to the next is referred to as: _______________________________ Examples: ______________________________ - not washing hands after going to bathroom (physical contact)! ______________________________ – Fluids generated from the reproductive system. ______________________________ – Blood carries many pathogen from one individual to the next ______________________________ - Breathing in infectious particles. o Not many pathogens are “airborne” - which means they float in the air. o Most travel in the tiny droplets of water after you sneeze – COVER YOUR MOUTH _______________________________ - Contaminated food and water. ________________________; An organism that may carry the pathogen from patient to patient for infection a.
