Document Summary

Anything over 60 is going to lead to growth of mold and bacteria: bathrooms, basements. Penicillum: construction issues lead to mold issues. Synergistic action between mold and bacteria increase negative health conditions (combined effort: serious infection of the lungs and can spread throughout the body, produce chemicals that suppress the immune system. Endotoxins: highly inflammatory, affect brain and other organs. Only way to control mold is to control moisture. Classified into 3 groups: allergenic molds, pathogenic molds. Present on top of molds and cause you to inhale, ingest, or touch. Liquid soluble and readily absorbed through airways and skin. Doctors never get to the root of the problem: can damage several systems. Antibiotics make it fungus friendly: kill good and bad bacteria. Antifungal drugs are toxic: affect the liver, attack the cells, damage human cell membrane. Starve mold out of your body, avoid foods that fuel fungal growth: cant grow in alkaline environment (fresh foods)

1.What does it mean for a bacterium to be âantibiotic resistantâ? In your opinion, what factors have led to the development of antibiotic resistant bacteria?

2. How does Penicillin work? In what other ways might Penicillin (and similar drugs) be used to inhibit a bacteriumâs ability to cause infection or persist in a host? (HINT: Think about the other structural features of a bacterium)

3. Antibiotic resistance is a serious threat to human health. What role do beta-lactamases have in increasing bacterial resistance to drugs such as penicillin? In the future, do you feel we will be able to âsolveâ the antibiotic resistance problem?

Experiment #1

Question: Does penicillin prevent infection?

Hypothesis: If the medicine prevents infection, than the medicine will prevent the growth of bacteria that cause infection.

Experiment: Leo placed two circles of paper in a 500 Petri dish (something used for growing bacteria).In 250 dishes, the paper was soaked with Peniccilin solution and then inoculated with bacteria. The other 250 dishes were soaked in water only and inoculated with same bacteria .All other conditions including light and temperature remained the same. After 48 hours, Leo observed all dishes and noticed there was no bacteria growth in the penicillin dishes a circle. All dishes with water only had large colonies of bacteria growing in them.

At the end of the experiment, a circle with a radius of 2cm formed around the circle of paper soaked in penicillin. There were no bacteria growing in the 2cm circle. No change had occurred around the other circle of paper. The bacteria were growing well.
