Ch 14: Pathogens & Disease

About This Chapter

In this chapter, we are looking at pathogens and disease. Our subject-matter experts created these lessons for you to enhance your knowledge of such things as infectious disease transmission routes, and pathogenesis.

Pathogens & Disease - Chapter Summary

Use of these lessons will broaden your knowledge base on pathogens and disease. You will be taking a look at types and causes of pathogens and disease, antibiotic resistance and virulence of pathogens, and more. You will be presented with material like:

  • Normal human flora in the prevention of disease
  • Meaning and examples of the chain of infection
  • Infectious disease transmission routes
  • Infection to recovery of disease
  • Neoplasia
  • Definition of pathogenesis

Lessons are short, which allows you to make continuous progress on your studies by logging in with your mobile device from wherever you are whenever you have a few minutes. Video lessons last about 5-10 minutes and we include a quiz at the end for your self-assessment. Track your progress on your dashboard. A test at the end of the course will ensure you understand all major concepts.

Preventing Disease: Normal Human Flora

1. 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.

The Different Routes of Infectious Disease Transmission

2. 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.

Chain of Infection: Definition & Example

3. Chain of Infection: Definition & Example

Infectious disease results from the interaction of an agent, a host, and an environment. Most of these diseases follow a typical chain of infection that ends with an infected host. Understanding the chain of infection can help with both the prevention and treatment of infectious diseases.

Pathogens and Disease: Definitions, Types & Causes

4. Pathogens and Disease: Definitions, Types & Causes

There are many different types of pathogens and many problems they cause. This lesson will teach you about four main types of pathogens, examples of each, and what problems they cause.

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.

Pathogens: Antibiotic Resistance and Virulence

6. Pathogens: Antibiotic Resistance and Virulence

Find out more about how the overuse of antibiotics could lead to some serious problems with epidemics or untreatable diseases in the future. You can also discover some of the things that make pathogens harmful and why pathogens don't cause disease in every species they infect.

What is Neoplasia? - Definition, Types & Examples

7. What is Neoplasia? - Definition, Types & Examples

This lesson will discuss the concept of neoplasia. We'll specifically talk about the differences between benign tumors, carcinoma in situ, and malignant tumors. This lesson will also define metastasis and oncology and show examples of different types of malignant and benign tumors.

Pathogenesis: Definition & Example

8. Pathogenesis: Definition & Example

In this lesson, we'll learn about pathogenesis. We'll examine the steps that are involved and follow an example of going through the pathogenesis process.
