The Urine Microscopic: Microscopic Analysis of Urine Sediment
Parasites which can be found in urinary sediment include all of the following EXCEPT:View Page
Parasites

Parasites which may be found in urinary sediments include Trichomonas vaginalis, Enterobius vermicularis and Schistosoma haematobium. It is also important to note that parasites and parasitic ova may be seen in urine sediments as a result of fecal or vaginal contamination. This slide shows examples of Trichomonas vaginalis. In the female, Trichomonas is usually found as a contaminant from vaginal infection and is often accompanied by an increase in the number of white cells. Trichomonas is highly motile, measuring 5 - 15 microns with a characteristic pear shape. It has multiple anterior flagella and the nucleus is often apparent.

Trichomonas under Phase-Contrast

Under phase contrast, Trichomonas organisms appear much darker than the surrounding white blood cells.

Trichomonas versus White Cells

When the urine cools or when the wet mount begins to dry Trichomonas begins to lose its characteristic motility and may easily be misinterpreted as white cell or epithelial cell.
