| A 31 year old male missionary worker recently returned from Africa where he helped a small rural community update their sanitation practices. He presented to his physician weak and complained of recent weight loss, abdominal pain, and diarrhea that was often bloody. The doctor ordered a battery of tests including a complete blood count (CBC) and stool for parasite examination. The CBC revealed eosinophilia and anemia. This suspicious form was seen on the wet preparations. It measured 52 µm by 27 µm. What parasite is mostly likely present? | View Page |
| A 6 year old female presented to the local clinic complaining of intense perianal itching and diarrhea. The doctor ordered a cellophane tape prep and stool for routine culture and parasitic examination. The cellophane tape prep revealed suspicious form on the left. The stool culture was negative. The form on the right was seen upon examination of the stool for parasites, which measures 10 µm. Label these two suspicious forms: | View Page |

| Parasites which can be found in urinary sediment include all of the following EXCEPT: | View Page |
| What element is present in this slide? | 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. | View Page |
| Enterobius Vermicularis Pinworm Ova Another parasite which may be seen in urine is the Enterobius vermicularis (pinworm) ova. The ovum is ovoid in shape with one side flattened. The embryo is separated from the shell by a clear space. | View Page |
| High Power of Enterobius vermicularis Ova On high power brightfield, the larva of Enterobius vermicularis can be seen within the thick hyaline shell. The egg measures 25 X 55 microns. | View Page |
| Phase-Contrast of Enterobius vermicularis On phase contrast, the larva appears darker. Note the clear space surrounding the larva. | View Page |
