Grace Crecelius Research Paper 12/11/2015 Disinfectants vs. Bacteria This project involves testing various disinfectants on bacteria covered toothbrushes to see which method is most effective. The three main methods of disinfectants are hydrogen peroxide, U.V rays to kill bacteria, and antibacterial soap. Learning what is in the various disinfectants that eliminate bacteria is beneficial to understanding the experiment. Bacteria are single-celled organisms that reproduce quickly. Pathogens are bacteria that cause sickness. Once the body is infected with pathogens, those bacteria reproduce and grow inside of cells in the body. As they grow, certain bacteria can make toxins; those toxins can damage the body’s cells. Symptoms of a sickness can be caused by those toxins. Pathogens can be spread from one person to another through physical contact or contact with bodily fluids. Bacteria however can be killed by sterilization, cold temperatures, antiseptics, disinfectants, and pasteurization. The antibacterial soap mentioned is a disinfectant that reduces bacteria, which therefore reduces chance of infection. Hydrogen peroxide is an antiseptic that reduces bacteria. The difference between antibacterial soap and normal hand soap is triclosan or triclocarbon. Triclosan is an antibacterial compound in antibacterial soap and a potent synthetic chemical. The text states, “Triclosan is classified as a broad-spectrum antimicrobial agent because it is effective against a wide range of
