Honey, I've Found a Solution! The Antibacterial Properties of Manuka Honey against S. epidermidis and S. salivarius

CSEF · 2019 Microbiology (Medical) (Junior Division Only) Third Award

Courtnie Bui · Fairmont Private Junior High School, Anaheim, Orange County

Overview

Objectives The goal of this experiment is to determine whether or not Manuka honey is comparable to common modern medicines as an antibacterial. Methods Tested whether or not Manuka honey could match up to Neosporin and ampicillin by inoculating agar dishes with either Staph. Epidermidis or Strep. Salivarius. Measured zone of clearance around antibacterial to determine comparability. Results Manuka honey is effective at killing Staph. Epidermidis bacteria, but not Strep. Salivarius. Neosporin and ampicillin both yielded no results, as proven by over 90 total trials. Manuka honey was more effective at killing bacteria than both modern medicines. Conclusions Manuka honey killed the external bacteria, indicating that Manuka honey can be an effective alternative to topical medications for bacteria found externally.

Summary statement

By testing it against two types of bacteria, I found that Manuka honey is an effective alternative to Neosporin because it killed bacteria that is found externally.

Help received

I was advised by my science teacher and a high school mentor on how to stay safe during the experiment as well as how to fine-tune my procedure to make it more realistic.
