Question

In which body fluid is Giardia lamblia found?

1) Blood
2) Urine
3) Stool
4) Saliva

Answer 1

Giardia lamblia is found in the stool and is transmitted through contaminated food or water via a fecal-oral route, causing giardiasis.

Step-by-step explanation:

The body fluid in which Giardia lamblia is found is stool (option 3). G. lamblia, also known as Giardia intestinalis or Giardia duodenalis, is a single-celled, flagellated protozoan parasite that colonizes and reproduces in the small intestine, leading to the illness known as giardiasis. This protozoan causes severe diarrhea and spreads via contaminated food or water through a fecal-oral route. It is important to note that this parasite is not found in blood, urine, or saliva. The correct answer to the question is therefore stool, which correlates with the fecal-oral transmission of the pathogen.
