TASK 5.2  Bacterial Disease Posters

Your task:

Individually make an informative A4 poster on one of the listed bacteria that causes a disease. This poster will be place on the walls and will be reviewed by your peers on Canvas.

Your poster must contain:

• The scientific name of the bacterium

• A description of the bacterium (what does it look like?)

• Where the bacteria is often found

• How the infection is transmitted (given from one person to another)

• The diseases that infection with this bacterium causes and the symptoms associated with the disease

• The specific treatment to remove the infection (if there is a treatment) AND/OR preventative measure to reduce occurrence of disease in a community

• Pictures and diagrams of the bacterium

• Statistics on the occurrence of the bacterial infection across the world

• A bibliography

• Your names on the poster

Options for Bacterial Disease:

1. Anthrax

2. Cholera

3. Diphtheria

4. E. Coli

5. Clostridium Tenani (Tetanus)

6. Tuberculosis

7. Streptococcus pyogenes (Scarlet Fever)

8. Mycobacterium leprae (Leprosy)

9. Pneumonia

10. Bordetella Pertussis

• Print and place on walls in RL5.

Practical:  Patient Zero

Instructions

Each cup of liquid represents human bodily fluids. Someone will receive fluids “infected” with a disease. You do not know who is “infected” and who is not, but this investigation will allow you to figure out who introduced the disease into the population. That person is the index patient, or Patient Zero.

Materials (for each student)

•  Safety glasses

• One disposable cup (numbered) with unknown liquid

•  One disposable plastic pipette

• One data collection sheet

Caution: Some of the liquids are poisonous to taste or touch. Do not drink any fluids in this lab. If a liquid spills on your skin, wash it off immediately with plenty of cold water.

Procedure

1. Choose a cup and pipette.

2. Record your cup number below.

3. If you have an odd-numbered cup, form an inner circle.

4. If you have an even-numbered cup, walk around the outside of the circle.

5. Only exchange once per round.

6. Do not exchange with the same person twice.

Round 1

1. When instructed, outer circle will begin to walk around the inner circle. When the teacher gives the signal, stop and stand in front of someone in the inner circle.

2. Once everyone has a partner, add 2 pipettes full of fluid from your cup to the cup of the person in front of you. Your partner will do the same. Stir with the pipette.

3. Record your partner’s cup number below. Wait for everyone else to finish.

Round 2

1. When instructed, the outer circle will walk around the inner circle again and each student will find a new partner.

2. Repeat the fluid exchanges just as in Round 1. Do not exchange with the same person twice.

3. Record your new partner’s cup number below. Wait for everyone else to finish.

Round 3

1. Repeat this procedure one more time. Be sure to find a new partner and do not exchange with the same person twice.

2. Return to your seat.

Final Step

Teacher will add an indicator solution to each cup. “Infected” students will see a color change.

Conclusion

Work out who Patient Zero is:

Write your name on the board and underneath it the names of participants with whom you exchanged fluids, in the

order in which the exchanges occurred. 

Highlight the names of the currently "infected" people.

If you "test positive" and find that everyone with whom you traded also tested positive, you may be Patient Zero.
