Abstract

The objective of this laboratory assignment was to assess the effectiveness of antiseptics in fighting bacteria. The sub-objective was to compare the antibacterial efficacy of four antiseptics: Family Guard, ECOS, Lysol H202 Bathroom, and Clorox Healthcare against the Escherichia Coli bacterial isolate. The experiment hypothesized that Clorox Healthcare was the most effective among the four antiseptics in the experiment. The experiment made use of the agar disk diffusion method. The laboratory results showed that generally, the four antiseptics were effective against the E. Coli bacterial isolate. In line with the hypothesis, Clorox Healthcare reported the highest antibacterial efficacy against the E. Coli as measured by the size of its inhibition zone. Larger inhibition sizes indicate that the antiseptic is able to prevent growth of more bacteria and is hence, more effective. Generally, the results showed that antiseptics have different levels of antibacterial efficacy. Consequently, some antiseptics are more potent than others. This is because of differences in formulations and chemical compositions that result in different potency levels. The general conclusion of the laboratory experiment is...

The results indicate that Clorox has the highest antibacterial efficacy among the four antiseptics as measured by the diameter of its inhibition zone. This supports the hypothesis that Clorox is more effective than the other brands in fighting the E.Coli bacteria. The general conclusion drawn from the results is that antiseptics are effective in fighting against bacteria, although their efficacy depends on their chemical composition.
