  2. The Spreading of Disease: Infection • Infectious diseases spread in one of four ways: • Contact with infected person • Contact with contaminated object • Contact with infected animal • Contact with environmental source

  3. Carrier vs. Vector • Vector—insect spreading disease (tick, mosquito) • Carrier—organism that has a virus or bacteria but not showing the signs of the disease. • Person with HIV

  4. Antibiotics • Antibiotics work on bacterial infections • Bacteria can become antibiotic resistant • Due to overuse or not taken the medicine as prescribed. • Examples of antibiotics: • Z-packs, CepCor, Penicillin, etc

  5. Penicillin • Alexander Fleming discovered penicillin by accident • Penicillin is a fungus

  6. Vaccines • Vaccine—a weakened or dead version of the actual virus/bacteria given to you to force your immune system to build antibodies against the disease. • Flu shot

  7. Your Body • Pathogen—a microbe that cause disease • Antibodies—kill pathogens in body • Activity Immunity—organism gets virus and builds up antibodies for virus • Passive Immunity—inject with antibodies from another organism
