One potential solution to combat this problem is administering multiple antibiotics together to achieve antibiotic synergy; when two or more antibiotics work together to increase antibacterial efficacy. When considering potential synergistic combinations of antibiotics, one possibility is to utilize antibacterial plant extracts in addition to common antibiotics. The goal of our research was to compare the antibacterial properties of the Chinese medicinal plant bitter melon (Momordica charantia) and four common antibiotics alone or in combination with bitter melon against Micrococcus luteus, Pseudomonas putida, and Escherichia coli. We hypothesized that combining the antibiotics with bitter melon extract would result in increased antibacterial effects against one or more bacterial strains. Oil from dried bitter melon was prepared using the Soxhlet extraction method. Antibacterial properties of bitter melon extract and carbenicillin, streptomycin, colistin, and tetracycline alone or in combination with the extract were determined by performing disk diffusion assays. Diameters of the resulting zones of inhibition for the two treatments were measured and analyzed for statistical significance by performing a two-tailed, paired sample t-test using Rguroo. We found that bitter melon extract individually had little to no antibacterial effect against any of the organisms tested. Interestingly however, combining bitter melon extract with common antibiotics resulted in synergistic effects in some cases, as well as one example of antibiotic antagonism.<br />These results demonstrate that plant-derived extracts can enhance the antibacterial effects of commonly prescribed antibiotics if paired correctly.</p> ER -
