About This Chapter

Allow us to teach you some basic facts about diseases with our proven video lessons. Then, try out some sample test questions and get a feel for what you'll encounter on the OAE Biology exam.

OAE - Biology: Introduction to Disease - Chapter Summary

Use this study guide to learn in a way that makes complex subjects like infections and diseases seem a little less daunting. Our handy videos will help you study everything about diseases, from how we get them to how we get rid of them. Once done with this chapter, you'll be able to:

  • Differentiate between infection and disease
  • Discuss common methods of preventing diseases caused by normal human flora
  • Define and list examples of symbiotic interactions in disease
  • Chart the life-cycle of a disease from infection to recovery
  • List the different methods infectious diseases can transmit
  • Distinguish between endemics, epidemics and pandemics
  • Categorize different types of diseases
  • Examine common causes and effects of nosocomial diseases

These awesome video lessons will help you quickly retain the information. Each has been prescribed by our expert instructors to get your mind ready for the OAE Biology exam.

Objectives of the OAE - Biology: Introduction to Disease Chapter

Passing the Ohio Assessments for Educators (OAE) exam is a requirement for forthcoming teachers and teachers seeking re-licensure in Ohio. Instructors must only pass the OAE exam matched to the subjects they plan on teaching. Life science teachers with classes 7th grade and higher must pass the OAE Biology exam. In order to achieve a passing grade, test-takers must earn a score of 220 on a scale of 100 to 300. Questions are based on a set of standards for entry-level teachers as determined by the state of Ohio to be compulsory.

The OAE Biology exam consists of five domains, including one focused on biological unity and diversity. This section includes questions related to diseases that this study guide is designed to help you with. Twenty percent of the questions on the OAE Biology exam are in this domain. You will need to complete the computer-based OAE Biology test in three hours. The test is made up of 150 stand-alone multiple-choice questions.

Disease Control & Prevention

1. Disease Control & Prevention

Disease control and prevention can be accomplished in many ways. Learn the different ways to control disease, about getting a vaccine, antiseptics and disinfectants, vector control, and using sanitation to fight disease.
The Differences Between Infection and Disease

2. The Differences Between Infection and Disease

Infections and diseases cause damage to our health. Know the differences between infection and disease, the infectivity of pathogens, and how opportunistic infections affect the immunocompromised. Learn about the etiology of disease, idiopathic diseases, and the role of the immune system.
Preventing Disease: Normal Human Flora

3. Preventing Disease: Normal Human Flora

Normal human flora, microbes that live within or on a body, can prevent diseases by killing off harmful ones. Explore the flora in the gut and other locations, and understand the different types: opportunistic pathogens, mutualistic and commensal flora.
Symbiotic Interactions in Disease: Definition, Theory & Examples

4. Symbiotic Interactions in Disease: Definition, Theory & Examples

Symbiotic interactions are the close relationship between two different species and results in positive, neutral, or negative effects for one or both of the species. Learn more about the definition and theory, and examples of symbiotic interactions in disease, including symbiosis, mutualism, commensalism, parasitism, and obligate and facultative symbiosis.
Progress of Disease: Infection to Recovery

5. Progress of Disease: Infection to Recovery

The five steps of the disease process define the progression of disease from infection to recovery. Take a metaphorical train ride and learn about the incubation period, prodromal period, period of illness, period of decline, and the period of convalescence in the progress of a disease.
The Different Routes of Infectious Disease Transmission

6. The Different Routes of Infectious Disease Transmission

The different routes of infectious disease transmission are the possible ways that pathogenic microbes can be transmitted. Learn about horizontal versus vertical disease transmission, as well as vectors, fomites, and the vehicles of infectious disease transmission.
The Spread of Disease: Endemic, Epidemic & Pandemic

7. The Spread of Disease: Endemic, Epidemic & Pandemic

The spread of disease is caused by a number of factors like population size, hygiene, unsanitary conditions, and the rate of microbial mutation. Learn about the definitions of endemic disease, epidemic versus pandemic disease, and factors that determine the spread of disease.
What Are the Types of Diseases?

8. What Are the Types of Diseases?

Diseases are often categorized into types based on certain characteristics of development. Learn about acute vs. chronic disease, primary vs. secondary disease, and local vs. systemic disease.
Nosocomial Infections: Definition, Causes & Prevention

9. Nosocomial Infections: Definition, Causes & Prevention

Nosocomial infections are infections that patients acquire while in hospital care. Learn about the definition, causes, and common nosocomial infections.
Establishment of Disease: Entry, Dose & Virulence

10. Establishment of Disease: Entry, Dose & Virulence

Diseases are first established in the human body once an infection has entered and can go on to cause many illnesses. Learn more about this process, how an infection makes entry into a host, the pathogenicity of diseases, and the different levels of doses: virulence, lethal, and infectious dose.
