| A 16 year old male champion athlete went to his doctor complaining of a persistent cough, fever, bloody diarrhea and overall weakness. Upon questioning the patient, it was learned that he had recently competed in a freshwater swimming competition in the Caribbean. Examination revealed a dermatitis on the patient's right calf. A battery of tests were ordered including a CBC, chemistry profile, and a stool for culture and parasitic examination. The CBC revealed the presence of eosinophilia. The other hematology and chemistry tests were unremarkable. The culture was negative. This suspicious form was seen on all parasite preparations made from the stool sample submitted. This form measures 165 µm by 68 µm. This patient is most likely suffering from an infection with: | View Page |
| A 40 year old male just returned from a six-month tour of the Far East. He went to his doctor upon his return complaining of weakness, diarrhea, fever and cough. Upon questioning the patient it was learned that he spent many an evening swimming in the various local fresh water ponds. The doctor, suspicious of a parasitic infection, ordered a stool for examination. Two suspicious forms were seen: form 1 is roundish and measures 77 µm by 62 µm. Form 2 is long and ladder-like and lays on the edge of form 1. What are these two structures? | 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 |
| Schistosoma Haematobium Ova The third parasite which may be seen is the Schistosoma haematobium ovum. This parasite is considered an important factor in the etiology of carcinoma of the bladder. The ova are elongated and are 60 X 160 microns. They are a yellowish color, slightly transparent, and possess a delicate terminal spine. | View Page |
