How are Parasitic Infections Observed in Histology?
Parasitic infections can be challenging to diagnose histologically due to the varied morphology of parasites. Common methods include Giemsa staining and hematoxylin and eosin (H&E) staining. Parasitic structures, such as protozoa, helminths, and their eggs, can be identified based on their distinctive shapes and sizes. Histological examination often reveals eosinophilic infiltration, tissue damage, and sometimes the direct visualization of the parasites.
