Foodborne Illnesses and Bacterial Infections of the Gastrointestinal Tract - Chapter Summary and Learning Objectives

Have you ever had a stomach bug? You know where your stomach doesn't feel just right, but you can't really pin down the cause? Most of the time, people just toss off a stomach bug as the flu. However, there are actually many different types of illnesses that can cause problems in your gastrointestinal tract. In this chapter, we will cover some of these illnesses that are caused from eating bad food and by bacteria. You'll take a look at several illnesses you may have heard of before, like cholera and dysentery. We'll also go over things like botulism and salmonella. You'll study the different illnesses, their symptoms and causes so you can better understand how a simple stomach bug may actually be something more than the flu. Topics covered in these lessons also include:

  • Difference between food poisoning and foodborne infection
  • Strains of E. coli
  • Typhoid fever
  • Causes of ulcers
