CASE #2 A 25-year-old Peace Corps worker has just returned from service in Ethiopia. She experiences a sudden onset of asthma-like symptoms. She has no previous history of asthma. An O & P (ova and parasites) on her stool was part of the normal discharge physical, considering the area of assignment, before being released from the Peace Corps. The sample was processed according to standard laboratory procedures. Two suspicious structures were noted during the direct saline wet preparation. The first of the two structures is noted in form #1; it measures 50 x 40 um. The second structure is depicted in form #2 and measures 18 um in diameter. Form 1 Form 2 1. Which of the structures is (are) considered a pathogenic parasite(s)? 2. Do the presenting symptoms relate to the O & P findings? If so, explain.

Transcribed Image Text:CASE #2
A 25-year-old Peace Corps worker has just returned from service in Ethiopia. She experiences a
sudden onset of asthma-like symptoms. She has no previous history of asthma. An O & P (ova and
parasites) on her stool was part of the normal discharge physical, considering the area of
assignment, before being released from the Peace Corps. The sample was processed according to
standard laboratory procedures. Two suspicious structures were noted during the direct saline wet
preparation. The first of the two structures is noted in form
# 1; it measures 50 x 40 um. The second structure is depicted in form #2 and measures 18 um in
diameter.

Which of the structures is (are) considered a pathogenic parasite(s)?
Do the presenting symptoms relate to the O & P findings? If so, explain.
Look at the structure depicted in form #1. What key characteristics allow you to identify the
organism? Name the organism and its stage.

Transcribed Image Text:Look at the structure depicted in form #2, What characteristics are key to its identification?
Name the organism and its stage.
What is (are) the common name(s) for the structure(s) identified as pathogenic parasites(s)?
6. What would be the most common route of infection of the structure identified in form #2?
7. What is the infective form of the structure identified in form #1 and how does it infect humans?
8.
