PARASITOLOGY- EXAM REVIEW- QUIZ
QUESTIONS WITH DETAILED VERIFIED
ANSWERS / ALREADY GRADED A / 2025
If a parasite has a sexual stage, the host in which this stage occurs in is: - ANS-DEFINITIVE HOST: the host
which harbors the adult or sexual stages of the parasite
In the US, with temperate climate, the most frequently encountered enteric parasites are: - ANS-
Cryptosporidium and Giardia
The Bristol Stool Chart is a reference for evaluating feces based on: - ANS-Consistency
In a hospital setting, a specimen of unformed feces is brought to the lab immediately after collection;
you know that it cannot be examined immediately so you would: - ANS-Mix a sample of it into 10%
formalin and a sample into polyvinyl alcohol (PVA)
We are increasing use of immunoassay in parasitology, our concern is/are - ANS-The compatibility if the
fixative(s) used to preserve the fecal specimen
The possibility of "missing" (not detecting) parasites other than those detected by the immunoassay
"Non-traditional" parasitology stain(s) that now have an important role in parasitology microscopy
include - ANS-Calcofluor white stain;
Modified (reduced decolorization) acid fast stain; and
Gram stain
In a temperate climate, in a developed country, e.g. the US, what factors may influence the type of
parasites one might expect to see in fecal specimens - ANS-Rural vs. urban setting
Travel history of patients submitting specimens
Racial and ethnicity considerations of the patients served
