We recommend using a Quizlet; Related Studylists Medical microbiology report. The act of handwashing is an example of degerming, in which microbial numbers are significantly reduced by gently scrubbing living tissue, most commonly skin, with a mild chemical (e.g., soap) to avoid the transmission of pathogenic microbes. Ideally, disinfectants should be fast acting, stable, easy to prepare, inexpensive, and easy to use. The genetic material of cells is found as molecules called DNA.

Sterile fields are created according to protocols requiring the use of sterilized materials, such as packaging and drapings, and strict procedures for washing and application of sterilants. Physical and chemical methods of microbial control that kill the targeted microorganism are identified by the suffix -cide (or -cidal). For example, bacteriostatic treatments inhibit the growth of bacteria, whereas fungistatic treatments inhibit the growth of fungi. What can be revealed about the patients infection? This suit has its own air supply and maintains a positive pressure relative to the outside, so that if a leak occurs, air will flow out of the suit, not into it from the laboratory. 35 terms babyboss729 Do my homework now. 5 Jun.
