What parasites are visible in fecal sample?

Common parasites visible in fecal samples include Giardia lamblia, which appears as small, motile cysts, and Entamoeba histolytica, identifiable by its larger cysts. Additionally, intestinal helminths like roundworms (Ascaris lumbricoides) and tapeworms (e.g., Taenia species) can be seen as eggs or segments. The presence of these parasites can indicate gastrointestinal infections and help in diagnosing related diseases. Microscopic examination is typically required to identify them accurately.
