GERMS Are EVERYWHERE Air, plants, food, soil, water, all
surfaces Even in our BODIES ! Our immune system protects us
against them except for a few nasties and those microbes that mutate
BACTERIA 1 celled organisms visible only thru
microscope So small that 1,000 bacteria can wrap
themselves around 1 pencil eraser Shapes: rod, sphere, spiral Not all are harmful – only 1% cause
disease Ex: Lactobacillius acidophilus
MRSA Methicillin resistant staphylococcus
aureaus Blamed for 94,000 infections in 2005
and 19,000 deaths Dangerous because it is resistant to
broad spectrum antibiotics Symptoms begin with small red bumps
that get larger + fever + rash + heat + swelling + pus + painful
HOW TO PROTECT YOURSELF: Wash Hands !!! Keep Personal Items Personal
Don’t share combs, brushes, razors, jewelry, soap, towels, equipment, headphones, cell phones
Keep open wounds/sores covered with sterile, dry bandage
Shower with soap and water Wash towels, sheets, clothes, uniforms Use antibiotics properly
VIRUSES Tiny capsules that hold genetic
material Reproduce by invading cells, injecting
their DNA, killing host cell Antibiotics are INEFFECTIVE Ex: AIDS, Influenza, Ebola, genital
herpes, measles, smallpox
PROTOZOA Single cell organism Some are harmless and live in our
intestines Harmful = Giardia, Malaria
HELMINTH Can enter your body, take up residence
in your intestinal tract, lungs, liver, skin, brain through nymph stage or larval/egg stage
OUR IMMUNE SYSTEM PROTECTS US Except… When to seek
medical care: Animal/human bite Difficulty breathing Cough that lingers
more than one week Fever 100+ Rapid heart rate
Rash that doesn’t go away
Rash + Fever Redness + swelling
+ pain + pus + Fever
Blurred vision Persistent vomit Unusual/severe
headache
