McDonnell provides a basic understanding of the various chemical and physical methods for antisepsis, disinfection, and sterilization to prevent infection and control contamination. Disinfection and sterilization technologies are used to control microorganisms on surfaces, in products, or in the air, he explains, while antisepsis is particularly associated with microbial reduction on the skin or mucous membranes. Among the topics are cold temperatures, essential oils and plant extracts, metals, biocides used as antiseptics, radiation sterilization, intrinsic bacterial resistance mechanisms, and mechanisms of viral resistance.
