Study Notes

Microbes and Disease

Microbes: Bacteria, viruses, fungi, and protists
Pathogen: A microbe that causes disease
Bacteria causing disease: Produce toxins
Viruses causing disease: Invade and destroy cells
Pathogen transmission: Air (coughs, sneezes, talking), direct contact (touching, sex, animals), food, water
Airborne transmission prevention: Masks, isolation, improved ventilation
Direct contact prevention: Handwashing, condoms
Foodborne prevention: Thorough cooking, proper storage temperatures
Waterborne prevention: Using sterile water
Physical body barriers: Skin, stomach acid, scabs, tears, mucus, cilia
Pathogen-killing cells: White blood cells
Long-term immunity: Memory cells
Antibody producers: White blood cells and memory cells
Vaccine: Dead or weakened pathogen
Vaccine's effect on the body: Stimulates the immune system
Vaccine's effect on memory: Stimulates memory cells for a specific pathogen
Vaccination advantage: Faster, higher antibody production
Herd immunity: Enough immunity in a population to stop pathogen spread
Antibiotics: Drugs to treat bacterial infections (damage cell walls)
Painkillers: Drugs to treat disease symptoms (not cure)
Penicillin source: Fungi
Antibiotic resistance: Bacteria DNA changes, preventing antibiotic killing
Antibiotic resistance causes: Overuse, incomplete antibiotic courses
Aseptic technique: Practices to prevent microbe contamination
Antiseptic effect indicator: Clear area around an antiseptic disk, showing bacteria killed
