Title: Infections, Antibiotics, and Vaccination


1
Infections, Antibiotics, and Vaccination
2
How to reduce the chances of being infected
  • Avoid crowded areas especially if you have a
    compromised immune system
  • Wash your hands often and thoroughly
  • Wash food thoroughly and ensure that all food is
    cooked properly
  • Avoid sharing drinks or other objects used by
    others
  • Use gloves when working with objects that are
    dirty or may be contaminated with bacteria

3
How to treat infections Antibiotics
  • Antibiotics are materials taken from bacteria or
    fungi, which are used to destroy harmful bacteria
    or fungi.
  • E.g. Penicillin (made from the mould Penicillium
    notatum) is used to destroy the bacteria cell wall

Note Antibiotics are not used for virus
4
Antibiotics and Resistance
  • Antibiotics kill nearly all bacteria
  • The variations of bacteria that are not affected
    by the antibiotics are antibiotic resistant.
  • Those bacteria will then reproduce and
    repopulate. The result is that nearly all of the
    bacteria living will be antibiotic resistant.
  • ?Evolution

5
Antibiotics and Resistance
  • Many parasitic bacteria (and fungi) are becoming
    resistant to many drugs.
  • E.g. Some tuberculosis causing bacteria are now
    resistant to 7 different antibiotics
  • A new super bacteria may be the potential
    outcome

6
Antibiotics The Good and Bad
  • Good Antibiotics help treat diseases, reduce
    the risk of disease, and can even help promote
    growth
  • Bad Antibiotics not only kill bad bacteria, but
    good bacteria as well
  • Can eliminate most good bacteria, especially in
    the digestive system
  • Bad Antibiotic resistance

Antibiotics vs. Vaccination
Antibiotics Vaccinations
-Bacteria (Good and Bad), fungi, protists Destroys which organisms? -Viruses, Bacteria (in some cases)
-Breaks down structure of the bacteria causing it to die How does it work? -Stimulates the body to develop an immune response to kill the virus in the future
-Various components What is it made of? -Dead or inactive components of a virus or bacteria
- Affects good bacteria and can cause fever, nausea, and diarrhea What are the side effects? -Few side effects (most allergy related)
8
Vaccine Dilemma and Community Immunity
  • Few scientific journals reported that vaccination
    caused severe side effects including autism and
    other disorders
  • The journals were proven to be incorrect, yet
    many refuse to get vaccinated
  • When most people are vaccinated nearly everyone
    is protected through Community Immunity
