Differences between sterilization, disinfection, antisepsis, degermination, and sanitization

 

Discuss the differences between sterilization, disinfection, antisepsis, degermination, and sanitization. Would it still be possible to see the presence of microorganisms after achieving disinfection or antisepsis?

Sample Solution

Sterilization, disinfection, antisepsis, degermination, and sanitization are all methods of controlling microbial growth but they differ in terms of their effectiveness & purpose. Sterilization is a process used to completely remove or destroy all living microorganisms from a substance through physical or chemical means like radiation or high temperatures (Ullmann’s Encyclopedia 2015). Disinfection on the other hand is used to reduce the number of viable microorganisms on surfaces/objects but does not eliminate them entirely as some may still survive depending on the agent employed (CDC 2020).

Antisepsis refers to reducing microbial levels by using antiseptics—chemicals that can be applied externally such as ethanol which kills microbes upon contact but is unable to penetrate deeper into bodily tissues. Degermination is similar in that it seeks to remove germs from an object, however, this term usually applies specifically when washing hands with soap & water; while sanitization involves reducing contaminants on surfaces/items to safe levels through a combination of practices such as cleaning & disinfecting (WHO 2020).

that time and used adjectives describing characters and settings that belonged to the period but also showed the reader exactly how the characters that inhabited this town viewed them. “Maycomb was an old town, but it was a tired old town when I first knew it. In rainy weather the streets turned to red slop; grass grew on the sidewalks, the courtyard sagged in the square,” (Lee 5) our protagonist Scout comments at the beginning of the novel. These descriptions are old-fashioned, developing the setting magnificently, but again, this could be hard for the reader to connect with since this is an unfamiliar setting. In The Perks of Being a Wallflower, the grammar and language used is very intimate and personal. Charlie begins the novel with “I am writing to you because she said you would listen and understand and didn’t try to sleep with that person at that party even though you could have.” (Chbosky 2) From the first sentence in the book, we learn about the introverted mindset of the character, which adds to the reader’s empathy towards our protagonist and his unique modern worldview. Paper Towns has an abundance of “John Green-isms”, certain stylistic choices in Green’s writing that make his novels contemporary and sets them apart from others. Quentin tells Margo before their quest of revenge that “I’m IM’ing with Ben Starling.” (Green 25), and later, Margo tells Quentin that “Everything’s uglier up close.” (Green 57) These statements are exclusively used in our 21st century, and so the reason John Green’s novels have struck chords as tales of adventure and self-discovery with modern youth readers is because the slang used in his stories’ amusing situations remind us of our own eccentric lives. Through these examples, we can understand that prose tends to be emphasized in literary fiction whilst mainstream fiction will utilize unique stylistic writing in order to get to the meat of the narrative. In literary fiction, the plot isn’t the main focus of the novel; rather, the social issues and character developments at the time are infused throughout the writing. This also proves my point that language and grammar can also affect how modern readers read literary vs. mainstream stories of self-discovery.

 

 

The contemporary setting of the 21st century has changed self-discovery, or how people “come of age” in fiction, therefore changing the viewpoints of millennial readers. History, conflict, and language changes, just like anything else over time. The farther away we stray from traditional values, the harder it can be to connect to characters coming of age in stories set in times that we no longer live i
