Answer:
No, Giardia is a protozoan that does not cause eosinophilia.
Explanation:
Eosinophilia refers to an increase in the number of eosinophils in the blood. The eosinophil is one of the white blood cells. When this occurs, the circulating eosinophils might be over 400 or 500.
Many factors might cause. One of them is parasite infections, in which helminths trigger the IgE generation, producing eosinophilia.
In the presence of the parasite antigen, eosinophils have a shorter medullar generation time, and they express a higher number of receptors for IgE and IgG. Their function is to damage the parasite, directly or indirectly, and to decrease the damages caused by their presence.
Giardia, among other protozoans, does not cause eosinophilia. Yet some other protozoans and parasites might induce it.
