CHAPTER 1 Introduction
1-4. Identify and describe the main factors
that account for the increased prevalence
of parasites in nonendemic areas of
the world.
1-5. Choose populations of people at risk of
contracting a parasitic infection.
1-6. Identify and describe the primary modes of
parasitic transmission.
1-7. State the primary function of a host in a
parasite-host relationship.
1-8. Explain, in general terms, the parasite-host
relationship.
1-9. Give an example of a parasite defense
mechanism that serves to protect it from a
host’s immune system.
1-10. State the two common phases in the
parasitic life cycle and the significance
of each.
1-11. Identify and describe the key pieces of
information that may be extracted from
each of the two common phases in the
parasitic life cycle.
1-12. List the major body areas that may be
affected as the result of a parasitic
infection.
1-13. Name the most commonly observed
symptoms associated with parasitic
infections.
1-14. Cite examples of available treatment
therapies to combat parasitic
infections.
1-15. Outline possible parasite prevention and
control strategies.
1-16. Select the most commonly submitted
specimen type for parasitic study.
1-17. Summarize, in general terms, the
components of the ova and parasite (O&P)
traditional parasite processing technique
performed on a variety of samples including
stool.
1-18. Give examples of newer parasite recovery
techniques.
1-19. State the name of each of the three
major groups of the clinically significant
parasites.
1-20. Differentiate Protozoa, Metazoa, and
Animalia in terms of definition and the
members of each group.
1-21. Analyze case studies with information
pertinent to this chapter, and:
A. Interpret and explain the information,
data and results provided.
B. Define and explain the parasiteassociated
terms and processes
associated with the case.
C. Construct a generic parasite life
cycle.
D. Determine possible parasite-associated
epidemiology, generic, symptoms
and disease processes, treatment,
and prevention and control
measures.
E. Explain the parasite-related processes
going on in the case.
F. Propose subsequent actions to
be taken and/or solutions, with
justification.
G. Design an informational brochure that
contains generic information about all
or select aspects of parasites.
CASE STUDY 1-1
UNDER THE MICROSCOPE
Joe, a third-year medical student, presented to his physician
complaining of severe diarrhea and abdominal pain
and cramping. Patient history revealed that Joe recently
returned home after a 3-month medical missionary trip to
Haiti. Suspecting that Joe might be suffering from a parasitic
infection, his physician ordered a battery of tests,
including a stool sample for parasite examination using a
traditional O&P technique.
Questions and Issues for Consideration
1. What is a parasite? (Objective 1-21B)
2. Indicate where Joe might have come into contact with
parasites and identify the factors that likely contributed
to this contact. (Objective 1-21D)
3. Name two other populations that are at risk of contracting
parasitic infections. (Objective 1-21D)
4. Name two other symptoms associated with parasitic
infections that individuals like Joe may experience.
(Objective 1-21D)
5. What are the key components of a traditional O&P
examination? (Objective 1-21B)
