1. Antiseptics, Disinfectants & Sterilization
This lesson will discuss the differences between antisepsis, disinfection, and sterilization as well as some of the methods used for sterilization and antiseptic compounds you may have used yourself.
2. Autoclaves and Moist Heat Sterilization: Use With Surgical Tools
This lesson will discuss what an autoclave is, how it works, and what it's used for. We'll also discuss the disadvantages of an autoclave, bacterial endospores, and how sterilization is important in the context of nosocomial infections.
3. Sterilization by Irradiation: Method & Types
This lesson will talk about ionizing and non-ionizing radiation, what they're used for and what the different types are. For example, we'll touch base on gamma irradiation, electron irradiation, x-ray irradiation and U.V. radiation.
4. What Is Gas Plasma Sterilization? - Definition and Applications
This lesson discusses something known as plasma as well as hydrogen peroxide gas plasma, ions, electrons, and more. We'll talk about how gas plasma is used for sterilization and what it kills.
5. Sterilization by Filtration: Advantages & Disadvantages
This lesson will cover how sterilization may be achieved through the process of filtration. We'll discuss how it works, what it is, its advantages and disadvantages, and much more.
6. What Is Pasteurization? - Definition & Common Uses
This lesson will discuss pasteurization, Louis Pasteur, and mastitis. We'll focus in on how pasteurization works, what it's used on, and why it's important to your health.
7. Understanding How Sterilization Is Quantified
This lesson will describe what certain values, such as the D-value, F-value, Z-value, and thermal death time mean and how to calculate the D-value given certain specified criteria.
8. Using Alcohol as a Disinfectant and Antiseptic
This lesson will discuss how alcohol can be used as a disinfectant and antiseptic but not a sterilant. We'll also talk about what it kills and doesn't kill and why ethyl alcohol and isopropyl alcohol are the two most commonly used alcohol-based disinfectants.
9. What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages
We will explore a disinfectant known as phenol. We'll cover what its mechanism of action is, what it can and cannot kill, its advantages and disadvantages and its involvement in enzyme systems.
10. Chlorine and Quaternary Ammonium Compounds: Advantages and Disadvantages
This lesson covers the very common and well-known disinfectants chlorine and quaternary ammonium. We will talk about their advantages, disadvantages, and uses in addition to the types of microbes they can kill.
11. What Are Peroxide Antiseptics? - Definition, Types & Uses
We will discuss chemical substances known as peroxides. You'll learn about hydrogen peroxide and peracetic acid as well as the way by which they kill microbes and whether or not they are used as a sterilant, disinfectant, or antiseptic.
12. What Is Ethylene Oxide? - Uses, Safety & Technology
This lesson will discuss how a type of gas, called ethylene oxide, can sterilize equipment. We'll talk about the way by which it does this, what its advantages are, as well as the dangers it poses to human health if used improperly.
13. Chlorhexidine, Iodine & Silver: Uses and Modes of Action
This lesson will discuss four commonly heard of chemical antiseptics: namely, iodine and iodophors, silver nitrate, silver sulfadiazine, and chlorhexidine, and it will cover the ways by which they kill microbes.
14. Sodium Hypochlorite: Structure, Uses & Formula
When our favorite white T-shirt gets badly stained, we reach for our favorite laundry detergent that contains bleach. The bleaching agent present in the detergent is a chemical called sodium hypochlorite, which is the focus of our discussion in this lesson.
15. What Are Antibiotics? - Definition, Types & Side Effects
Antibiotics are medicines created to fight infections caused by bacteria. They accomplish this by destroying the bacteria in a variety of ways. Learn more about how antibiotics work and take a short quiz at the end.
