A researcher is investigating the antimicrobial efficacy of three different natural honey varieties (Manuka, Clover, and Heather) against Staphylococcus aureus, a bacterium responsible for skin infections.
The researcher is provided with an agar plate that has already been inoculated with a uniform lawn of Staphylococcus aureus, alongside sterile paper discs saturated with each of the three honey varieties.
Describe how the researcher should use these materials to safely and accurately determine which honey variety is the most effective at inhibiting the growth of the bacteria.
