| | Pneumonia. |
| | Abstract | The herb Basil is known for its medicinal properties (1-2). For the past |
| | four years, I have been studying the antimicrobial properties of basil. |
| | Last year, I found that basal protects human lung cells from K. |
| | pneumoniae, a gram negative bacteria. This year, I will be testing to |
| | see if basil can protect lung cells from S. pneumoniae, a gram positive |
| | bacteria. My results, from my project last year, showed that although |
| | the basil did not kill all of the bacteria, it was still able to keep almost all |
| | the cells alive. Therefore, I will also be studying the mechanism by |
| | which basil protects the cells. I expect that basil will protect cells from |
| | gram positive bacteria equally as well as a gram negative. I also expect |
| | that the basil will protect the cells by facilitating the release of protective |
| | substances and inhibiting harmful substances. I will conduct my |
| | experiment by pretreating the lung cells with a 1% solution of organic |
| | basil powder and incubating for 24 hours. Following this, it will be |
| | infected with bacterial suspension (1000 cfu). I will then analyze the |
| | viability with trypan blue dye. I will also collect the media that had |
| | contained the cells, and examine the changes in levels of proteins such |
| | as cytokines using ELISA. A scientific report which connected |
| | pneumonia related mortality to increased levels of proinflammatory |
| | cytokines prompted me to select cytokines.(3) At the end of my project, |
| | I expect the results to show that basil protects gram negative, as well as |
| | gram positive bacteria and that it will increase the levels of anti |
| | inflammatory cytokines and/or decrease the levels of proinflammatory |
| | cytokines. |
