The class read pages 33-34 in their textbook and then took the following notes on bacteria, viruses and the immune system... -Micro-organisms = bacteria (prokaryotic), viruses (not living?) and some fungi (eukaryotic) -The immune system is a line of defense against pathogenic micro-organisms -1st line of defense = skin, saliva, stomach acid and mucus -2nd line of defense = white blood cells (WBC), fever, redness and swelling -Vaccines = can prevent the spread of diseases by using an inactivated or weakened part of the disease (viral or bacterial), so that your body can produce antibodies (created by WBC) -Antibiotics = are medicine made from micro-organisms to prevent bacterial diseases/infections. Over use of antibiotics can lead to antibiotic resistance -Immunity = resistance to a disease or pathogen -Herd Immunity = a group or population that is resistant/immune to a disease or pathogen - this means it cannot spread -Epidemic = regional or local outbreak of a disease -Pandemic = global outbreak of a disease Lastly, students worked on their Microbiology Project on Teams.
