3 Types of Infectious Organisms
|
1. Bacteria
2. Virus 3. Fungus |
|
Bacteria
|
-Prokaryotic (lack DNA in nucleus)
-Can be rod, round, or spiral -Can reproduce in 20 minutes -Can reproduce outside of host |
|
Examples of Bacterial Infections
|
1. Pneumonia
2. Skin Infections 3. Joint Infections 4. Urinary Tract Infections |
|
Treatment of Bacterial Infections
|
-Antibiotics
|
|
Virus
|
-Small infectious agent
-Eukaryotic (has nucleus with DNA and RNA) -Can't replicate outside of host -Can cause disease of organs (brains, lungs, skin, etc) |
|
Treatment for Viral Infections
|
Anti-viral medications
|
|
Fungus
|
-Eukaryotic organisms, like mold and yeasts
-Can grow like strings or thread -Causes infections in skin and other places |
|
Treatment of Fungal Infections
|
-Antifungal medications
|
|
How Do Infections Spread?
|
-Droplet and Airborne
-Aerosol -Water and soil -Direct Contact -Faeco-oral -Contaminated intermediates (sheets, pillow, doorknobs, etc) |
|
How Does the Body Prevent Against Infection?
|
-Immune System
-Blood (white blood cells) -Physical Barriers (skin, lungs) -Mechanical Barriers (coughing, crying) -Chemical Barriers (stomach acid) |
|
3 Parts of the Immune System
|
1. White blood cells
2. Thrombocytes 3. Lymphatic system |
|
White Blood Cells (Leukocytes)
|
-Cells of the immune system involved in defending the body against both infectious disease and foreign materials
-5 different types -Produced in bone barrow |
|
Lymphatic System
|
-A network of conduits that carry clear liquid called lymph around the body
-Transports white blood cells to and from the lymph nodes into the bones. |
|
2 Problems of the Immune System
|
1. Poor Defense (HIV, blood disorders, genetic disorders)
2. Autoimmune Disease (Lupus, rheumatoid arthritis) -Body attacks it's own tissue |
