About This Chapter
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

1. What Is a Foodborne Illness? - Definition and Common Types
In this lesson we will discuss illness caused by consuming contaminated foods. This will include defining the little known difference between food poisoning and food infection.
2. Cavities and Tooth Decay: Bacterial Causes of Common Dental Issues
Did you know that getting cavities in your teeth is an infectious disease? Cavities are a result of bacteria in the genus Streptococcus. In this lesson, we will examine how bacteria contribute to tooth decay.
3. What Is Botulism? - Food Poisoning Caused By the Bacterium Clostridium botulinum
The most toxic natural substance on Earth is not the venom of a snake or spider. Instead, it is a toxin made by a bacterium called Clostridium botulinum. We will examine Botulism, a type of food poisoning caused by this toxin.
4. Salmonella: Symptoms of Food Poisoning Caused By Salmonella
There is a very good reason for not eating raw cookie dough, despite how delicious it is. In this lesson, we will look at Salmonella, a bacterium often found in the dough's raw eggs, which can cause a serious case of foodborne illness.
5. What Is Campylobacter? - Infection Caused By Campylobacter Bacteria
You always hear about the dangers of eating undercooked chicken. In this lesson, we will examine Campylobacter, one common cause of bacterial food-borne infection acquired by eating raw poultry.
6. E. Coli: Common Strains and Pathogenic Varieties of E. Coli Bacteria
For each bacterial species, like E. coli, there can be many different strains. In this lesson we will discuss the common pathogenic strains of E. coli.
7. Escherichia Coli Infections: E. coli O157:H7
E. coli O157:H7 is one of the most infamous causes of foodborne illness. In this lesson, we will discuss how E. coli O157:H7 causes disease in the human host.
8. E. coli O157:H7 - Diagnosis, Treatment & Prevention
E. coli O157:H7 is one of the most infamous causes of foodborne illness. In this lesson, we will discuss the diagnosis, treatment, and prevention of E. coli O157:H7.
9. Listeriosis: Bacterial Infection from Listeria Monocytogenes
Women have a lot to worry about during pregnancy. In this lesson we will discuss one more threat to developing babies, the bacteria Listeria monocytogenes, and the foodborne illness it can cause.
10. Typhoid Fever: Symptoms, Causes and Salmonella Typhi
Have you ever heard of the infamous Typhoid Mary, a cook responsible for spreading disease to over a thousand unlucky diners? In this lesson, we will learn about typhoid fever and the causative organism Salmonella enterica serovar Typhi.
11. Food Poisoning from Clostridium perfringens & Clostridium Perfringens Enterotoxin
Clostridium perfringens is a common soil bacteria that causes a mild case of food poisoning. In this lesson, we will look at one particularly severe outbreak and the factors leading to the higher-than-normal number of deaths that occurred.
12. What Is Cholera? - Disease Symptoms and Vibrio Cholerae
Throughout history, outbreaks of cholera have devastated populations all over the world. In this first of two lessons, we will begin our investigation of cholera by looking at the bacterial species that causes the disease: Vibrio cholerae.
13. Cholera: Causes, Treatment and Prevention
Cholera is a deadly disease characterized by profuse, watery diarrhea. In this second lesson dedicated to cholera, we will examine the treatment and prevention of the disease.
14. What Is an Ulcer: Causes, Symptoms and Helicobacter pylori
Once thought to be caused by a stressful life and spicy foods, stomach ulcers have been causing severe pain in people for years. In this lesson, we will look at the bacteria Helicobacter pylori, now confirmed to be the real cause of most stomach ulcers.
15. Brucellosis: Infectious Disease Caused by the Brucella Bacteria
In this lesson we will learn about the bacterial pathogen Brucella. Brucella is a human and livestock pathogen that was also the first biological agent weaponized by the United States.
16. Dysentery and the Bacteria Shigella: Symptoms & Causes
You can catch all sorts of diseases from fecal-oral contamination. Shigella is a human fecal bacteria that can cause a potentially fatal dysentery by consuming as few as 10 cells, an amount far too small to ever notice.
17. Food Poisoning from Staphylococcus Aureus Bacteria
Staphylococcus aureus is a deadly bacteria often associated with life-threatening infections. Did you know that S. aureus can also cause food poisoning? In this lesson, we'll explore this often overlooked foodborne illness.
