Summary Introduction
Introduction:
Unicellular organism causes disease to humans like bacteria, archae etc. These organisms usually get into humans via opportunistic and contamination mode.
Case summary:
Some unicellular organisms are discussed in this case with the morphological and physiological character and also the sequence similarity of r RNA base. Comparing the two dichotomous key for these organisms, suggest which key is useful in laboratory identification and for classification.

Students have asked these similar questions
Bacillus cereus and Bacillus thuringiensis are very closely related species and cannot be distinguished clearly by biochemical tests and 16S rRNA sequencing. Designate TWO (2) ways that you may use to differentiate these two species.
How was Brocadia anammoxidan named? What or who was it named after?
(Organisms are often named for where they were found, unique morphological or metabolic features, name of the person who discovered it, etc. Attempt both genus and species name. For example, if my organism was Xanthomonas oryzae, I would Google “Xanthomonas word origin.” and “oryzae word origin.” Often a word origin is Greek or Latin, so Google your word followed by “Greek” or “Latin”)
What possible explanations have been proposed for the origins of H. luzonensis? In your own words, describe the evidence that supports these explanations. (Minimum of 2 complete sentences.)

- 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)? Do the presenting symptoms relate to the O & P findings? If so, explain. Look at the structure depicted in form #1.
