On completion of this chapter and review of
its figures and corresponding photomicrographs,
the successful learner will be able to:
4-1. Define the following key terms:
Axoneme (pl., axonemes)
Axostyle
Costa
Cytosome
Flagellum (pl., flagella)
Flagellate (pl., flagellates)
Median body (pl., median bodies)
Undulating membrane
4-2. State the geographic distribution of the
flagellates.
4-3. Given a list of parasites, select those
organisms belonging to the protozoan
group flagellates, subphylum Mastigophora.
4-4. Classify the individual flagellates as
intestinal or extraintestinal.
4-5. Construct, describe, and compare and
contrast the following life cycles:
A. General intestinal flagellates
B. General atrial flagellates
C. Each specific flagellate
4-6. Briefly identify and describe the populations
prone to contracting clinically significant
disease processes and clinical signs and
symptoms associated with each pathogenic
flagellate.
4-7. Identify and describe each of the following
as they relate to the flagellates:
A. Factors responsible for the
asymptomatic carrier state of an
infected patient
B. Treatment options
C. Prevention and control measures
4-8. Determine the specimen of choice,
alternative specimen type where
appropriate, collection protocol, and
laboratory diagnostic technique required for
recovery of each of the flagellates.
4-9. Given the name, description,
photomicrograph, and/or diagram of a
flagellate:
A. Identify, describe, and/or label its
characteristic structures, when
appropriate.
B. State the purpose of the designated
characteristic structure(s).
C. Name the parasite, including its
morphologic form.
4-10. Analyze case studies that include pertinent
patient information and laboratory data
and:
