1	Antibacterial Activity and Factors Impacting Antibacterial Stability of Southwestern Ontario Honey Pask, Jessica 22 August 2013 (has links) This thesis presents results from a two part, prospective study using honey collected from Guelph and surrounding area in southwestern Ontario. The first part determined the antibacterial of honey by collecting 26 samples of honey over two summers (2011-2012) and conducting microbroth and agar dilution assays and comparing the results to those of the criterion standard, Medihoney™ (100% manuka honey paste). Some honey samples from southwestern Ontario had antibacterial activity that was not significantly different from that of Medihoney™. The second part evaluated the effects of storage and gamma irradiation on the antibacterial activity of highly antibacterial honeys. It was found that storage for 8 months at 4°C and -20°C reduced the antibacterial activity of honey. The antibacterial activity of honey was not altered after gamma irradiation. / Pet Trust Fund Wounds Wound healing Medical honey Honey Manuka honey Storage Gamma irradiation Microbroth dilution Agar dilution Glucose oxidase Floral origins Pollen analysis
