Chapter 32.12, Problem 1CR
Summary Introduction
Cells of Salmonella and Campylobacter are responsible for food borne infections. These species inhabit the gastrointestinal tracts of human beings and cause food poisoning. They are mainly transmitted to human beings by the means of contaminated undercooked or uncooked food.

Which of the following is NOT true of bacterial exotoxins?
1. Important in the pathogenesis of many human diseases
2. Their toxic effect can be systemic, affecting cells distant from the primary site of infection
3. None of the other four answers (All are true of bacterial exotoxins)
4. Different exotoxins may affect different types of cells (e.g., nerves, gastrointestinal mucosa)
5. Some exotoxins have two components, A (active) and B (binding)
Write a 1-2 paragraph case study that accurately depicts the disease caused by Clostridium Botulinum. If your organism is transmitted in a specific location or under certain circumstances be sure your patient has been to those locations or engaged in those behaviors that would lead to transmission
Have the appropriate timeline in terms of incubation and length of illness.
Cover the important symptoms. You do not have to give all possible symptoms, just the typical one.
Provide some important laboratory test results without stating the name of your microorganism.
Provide the Epidemiology, Pathogenesis, Clinical Manifestations, Laboratory Tests, Treatment and Prevention.
Why does Helicobacter pylori cause ulceractions in the lining of the Stomach?
1)The microbes secrete a toxin that prevents the host from detecting invasion of the microbe and thus allows it to thrive in the stomach and damage the host cells.
2)After invasion of the microbe in the cells lining the stomach, they are no longer able to produce mucous to protect the host cells from acid erosion
3)The microbe produces an enzyme that causes the cell to produce potent digestive enzymes that erode the stomach lining.
4)Once the microbe has entered the stomach, it releases digestive enzymes that degrade the mucous secreting cells.
