6.3 Defence Against
Infectious Disease
- NATURE OF SCIENCE
- Risks associated with
scientific research
- Florey and Chain's tests on
the safety of penicillin would
not be compliant with current
protocol on testing
- Test penicillin on bacterial
infections on mice
- BLOOD CLOTTING
- Cuts in the skin are
sealed by blood clotting
- Clotting factors are
released from platelets
- The cascade results in the
rapid conversion of fibrinogen
to fibrin by thrombin
- Causes and consequences
of blood clot formation in
coronary arteries
- SPECIFIC VS
NON-SPECIFIC IMMUNITY
- Non-specific
- Skin and mucous membranes
form a primary defence
- Phagocytosis
- Specific
- Lymphocytes
- T cells
- B Cells
- Plasma B cells
- Antibodies
- Memory B cells
- ANTIBIOTICS
- Block processes that occur
in prokaryotic cells but not
in eukaryotic cells
- Some strains of bacteria
have evolved with genes that
confer resistance to
antibiotics and some strains
of bacteria have multiple
resistance
- Aim 9
- Science has limited means in
the fight against pathogens
- Viruses lack a metabolism
and cannot therefore be
treated with antibiotics
- HIV
- Effects on the immune system
- Reduction in the number
of active lymphocytes
- Loos of the ability to
produce antibodies
- AIDS
- Methods of transmission
- INTERNATIONAL-MINDEDNESS
- The spread and containment of
diseases such as bird flu
- Vaccination
- Aim 8
- The social as well as the economic
benefits of the control of bacterial
diseases around the world
