Microbiology Concept Map
By: Melanie & Samantha
5 Kingdoms
Dichotomous Key
Immune System Defence
1st Line of Defence
1) Skin
2) Nose hair
3) Cilia
4)Stomach Acid & Mucus
5) Coughing & Vomitting
Nose Hair
mild acidity and salinity
normal flora: heathy bacteria
prevent growth of harmful bacteria
filter pathogens
microscopic hair like structures carry out pathogens out of your repiratory tract
2nd and 3rd Line of Defence
1) White Blood Cells
2) Long Term Immunity
White Blood Cells
Long Term Immunity
1. Bacteria
a) Archaebacteria
- ancient
- extreme conditions
b) Eubacteria
- modern
- moderate conditions
2. Protista
3. Fungi
4. Platae
5. Animalia
easy organization and identification of a group of organisms or diseases
divided into have and don't have
eg) number of legs, winged, etc
macrophage: phagocytosis pathogens in the body
B Cells: mark foregin pathogens for destruction by macrophage and killer T-cells
memory B cells store information so the body can respond more quickly upon re-infection
killer T-cells work with B cells to destroy pathogens
work to boost antibodie production
5 Ways Vaccines are made:
1) live but weakened form
2) inactive form
3) part of the disease
4) deactivated desiease toxin
5) mimicked form
Helpful Bacteria
Harmful Bacteria
What are they made of?
1) Pili
- allow for exchange of DNA
2) Flagellum
- allow for movement
3) Capsules
- allow bacteria to remain dormant
4) Cell Wall
- outer protective layer
5) Cytoplasmic Membrane
- controls entry & exit from cell
6) DNA Loop
- genetic information
7) Basic Cell Organelles
- eg) lysosome, ribosome, etc

Food production
Symbiotic relationship with organisms
Probiotic bacteria help prevent and treat diseases
Recycle decaying material in soil and water
clean up toxic contamination sites and oil spills
Experimentation, Biotechnology & Lab Study
some bacteria can be toxic and pathogetic (disease causing)
How bacteria makes us sick
high population and "waste" produced is toxic to host
similar to mitosis
copy DNA
copy organelles
cell divides
allow bacteria to evolve
transfer antibiotic resistance
1) moist surface
2) food source
3) warmth
A. Lag Phase
B. Exponential
C. Stationary Phase
D. Death Phase
How they work
Wash hands, avoid coughing in hands
Pencillium & Streptomycin
Pencillium - preventing bacteria from constructing a cell wall.
Streptomycin - preventing bacteria from producing proteins.
