Effects of Different External Factors in Changing the Effectiveness of Various Antibiotics

CSEF · 2004 Microbiology

Lauren E. Ruh · Washington Academic Middle School, Sanger

Overview

Objectives/Goals I wanted to see medications reaction to a household substance which was mixed with bacteria. Methods/Materials I used 5 different medications, Duricef, Zithromax, Augmentin, Omnicef and Cifzil. Then mixed it with 4 different things you would find in your kitchen, salt, coffee, soap, wine. Next I put the household substance medication mixture on a disk (hole punched coffee filter) then the disk was placed into a petri dish infested with bacillus substillus (bacteria) then I recorded for two days. Results Salt .9 Wine 1.108 Soap .97 Control 1.016 Coffee .95 Those are the average of each household objects mixed with 5 different medications and bacteria. Conclusions/Discussion After completing my project I have found that wine is best at preventing bacteria growing while mixed with a medication. This does not increase the effectiveness of the drug though! The least effective household substance was salt.
