Each level requires a progressively greater level of precaution. The three categories are critical, semi critical, or noncritical. The degree of microbial control can be evaluated using a microbial death curve to describe the progress and effectiveness of a particular protocol. Inanimate items, such as doorknobs, toys, or towels, which may harbor microbes and aid in disease transmission, are called fomites. While this isn't normally an issue as the immune system takes pretty good care of most encountered pathogens, there are situations where microbial load (the number of infection pathogens on an item) needs to be carefully managed. Chemical agents used to destroy or inhibit pathogenic microbes on tissue. Control of microbial growth by chemical agents. Bacterial cell structures labster quizlet - 1.
