Ch 21: MTEL Biology: Introduction to Disease

About This Chapter

Your review of this chapter will help fill any gaps between your knowledge of diseases and the objectives of the MTEL Biology test. One of the many chapter areas includes a look at nosocomial infections, their causes and prevention.

MTEL Biology: Introduction to Disease - Chapter Summary

Check your familiarity with key terms used to denote symbiotic interactions in disease in one of the Introduction to Disease chapter lessons. This lesson, the topics that follow and more can be explored in video and text:

  • Progress of disease from infection to recovery
  • Routes of infectious disease transmission
  • Methods of disease control
  • The differences between infection and disease
  • Normal human flora
  • Virulence measurements and pathogenicity

An additional lesson takes you through the spread of disease and the differences among epidemic, endemic and pandemic. Each chapter lesson has a practice quiz for additional material and quick self-assessment.

Objectives of the MTEL Biology: Introduction to Disease Chapter

This chapter helps ensure that you're familiar with relevant objectives in the Human Anatomy and Physiology subarea of the MTEL Biology exam. Questions that could involve review material in this chapter would fall under subareas 17 to 19. Most exam questions are multiple-choice format. This chapter's quiz questions are likewise multiple-choice and may resemble those on the test, making them excellent practice for exam day! The exam's open-response portion does not have set focus areas and could potentially delve into disease-related content as well.

Disease Control & 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.

The Differences Between Infection and Disease

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.

Preventing Disease: Normal Human Flora

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.

Symbiotic Interactions in Disease: Definition, Theory & Examples

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.

Progress of Disease: Infection to Recovery

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.

The Different Routes of Infectious Disease Transmission

6. The Different Routes of Infectious Disease Transmission

This lesson will discuss the different ways you can get sick. We'll discuss how pathogenic microbes can be transmitted to you or someone else as we explore horizontal and vertical transmission as well as vectors, vehicles, and fomites.

The Spread of Disease: Endemic, Epidemic & Pandemic

7. 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.

What Are the Types of Diseases?

8. 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.

Nosocomial Infections: Definition, Causes & Prevention

9. 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.

Establishment of Disease: Entry, Dose & Virulence

10. 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.
