Polymer Antimicrobial Synergy Research, Samuel Smith, Charles V. Rice, Phd

Journal of Health Disparities Research and Practice

Recent studies have shown that certain polymers, such as branched polyethylenimine (BPEI), have the potential to be antimicrobial. We have been growing certain strains of Bacillus subtilis (B. subtilis) and Escherichia coli (E. coli) and adding in concentrations of ampicillin to find the minimum inhibitory concentrations (MICs). This allows us to add in different concentrations of BPEI to test for synergy between our antibiotic and our polymer.

To find the MIC of each antibiotic, we grew an overnight of the bacteria in Lysogeny Broth (LB) and let it inoculate for 20 hours. We then inoculated a 24 well culture cluster …

Determining The Antibacterial Efficacy Of Ylang Ylang (Cananga Odorata) Plant Extract On Staphylococcus Aureus, Maria T. Dizon, Johnny Aldan, Bsn

Journal of Health Disparities Research and Practice

The Ylang Ylang (Cananga odorata) plant extract is highly popular among the Commonwealth of the Northern Marianas Islands (CNMI) and is frequently used in local medicine. This can be attributed to its properties as an antiseptic, antidepressant, antiseborrheic, hypotensive, sedative, and nervine substance. It is also used in aromatherapy treatments, perfume, and cosmetic products all over the world. The key chemical constituents of the Ylang Ylang are linalool, germacrene, geranyl acetate, methyl benzoate, and p-cresyl methyl ether, which all contribute to its medicinal effects. With the presence of antibacterial properties, it may be used as an alternative to conventional …
