Match the descriptions and antimicrobial agents to the appropriate type of germicide to test your knowledge of alcohols, halogens, phenolic compounds, and quaternary ammonium compounds as germicidal chemicals. Halogens Solutions can be used chlorine as antiseptics or disinfect instruments and surfaces without leaving residue: Common disinfectant which oxidizes proteins and other cell components. Carbolic acid Quaternary Ammonium Compounds Compound reacts with membranes to destroy many vegetative bacteria and enveloped viruses. These compounds are ineffective against mycobacteria, naked viruses, and Pseudomonas species. Alcohols Aqueous solutions which can kill vegetative bacteria and fungi but not bacterial endospores or naked viruses: Ethanol or isopropanol Germicidal agent which can leave an antimicrobial residue after use. Cationic detergent which can be safely used on food preparation surfaces. Phenolic Compounds

Quaternary ammonium compounds (quats) are preferred in hospital setting over acidic-anionic detergents because quats are strongly bactericidal and can eradicate gram-positive bacterial infections without inducing resistant bacteria. Quats are also effective in mechanically removing dirt and disrupting the plasma membrane, which can lead to bacterial death. Unlike acidic-anionic detergents, quats only react with the plasma membrane and are not effective at full strength concentration.
