Students Will Review:
This chapter helps students review the concepts in a disease origins unit of a standard immunology course. Topics covered include:
- Types of diseases
- Nosocomial infections
- Normal human flora
- Symbiotic interactions in diseases
- Disease control and prevention
1. Disease Control & Prevention
This lesson will discuss the many different ways by which people can control disease. Everything from vaccination to sterilization and beyond will be mentioned so that you can better appreciate the large arsenal of tools at our disposal.
2. The Differences Between Infection and Disease
This lesson will go over the differences between an infection and a disease. We'll cover everything from prions and infectivity to opportunistic infections and idiopathic disease. We'll also learn what the etiology of disease is and much more.
3. Preventing Disease: Normal Human Flora
This lesson will give you a basic understanding of what human flora is. You'll learn about the different locations of flora, such as the gut, and what mutualistic, commensal, and opportunistic microbes are.
4. Symbiotic Interactions in Disease: Definition, Theory & Examples
This lesson will describe something known as symbiosis and symbionts. We will explore the three main types and examples of symbiotic relationships as we define mutualism, parasitism, and commensalism.
5. Progress of Disease: Infection to Recovery
This lesson will teach you about the five basic steps of the development of disease, what they are called, and what occurs during each phase. We'll talk about the incubation and prodromal period as well as the periods of convalescence, decline, and illness.
6. The Spread of Disease: Endemic, Epidemic & Pandemic
This lesson will talk about what an endemic disease is and how it is different from an epidemic. We'll also discuss how an epidemic differs from something known as a pandemic. Finally, we'll look at some examples of each to help solidify these points.
7. What Are the Types of Diseases?
This lesson will focus on the different types of diseases that a person may develop or contract. We'll discuss the differences between acute, chronic, primary, secondary, local, and systemic diseases.
8. Nosocomial Infections: Definition, Causes & Prevention
In this lesson, you will learn about what a nosocomial infection is. We'll discuss, in particular, the many reasons you may get such an infection, which types of pathogens are most likely to cause one, and the most common places in your body you may acquire one.
9. Establishment of Disease: Entry, Dose & Virulence
This lesson will delve into what predisposes an individual to get sick. We'll talk about things like the entry, dose, and virulence of a pathogen and how they play a role in the establishment of a disease.
10. Alpha & Beta Hemolytic Strep: Treatment
In this lesson, you will learn about the illnesses caused by the alpha and beta hemolytic streptococci bacterium and the various methods for treating each type of infection.
11. Strep Viridans: Infection & Treatment
What are the Strep viridans? It turns out they can be innocent, or they can be deadly. They are also becoming harder to treat. Find out what this is all about in this lesson.
