Title: Infections, Antibiotics, and Vaccination
1Infections, Antibiotics, and Vaccination
2How 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
3How 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
4Antibiotics 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
5Antibiotics 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
6Antibiotics 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
7Antibiotics 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)
8Vaccine 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
