| A 35 year old male presented to the local clinic complaining of abdominal cramps, severe diarrhea, and intestinal gas discomfort. A stool was collected for parasite examination. It was foul-smelling and light colored in nature. This suspicious form was recovered and measured 10 µm by 12 µm. The patient is infected with: | View Page |
| A 43 year old female presented to her doctor for a routine check-up. Her only complaint was that she had been experiencing watery stools that occasionally contained pus and blood. Examination revealed tenderness in her abdomen. A stool for parasite study was sent to the lab. Two suspicious forms were seen. The oblong form on measured 53 µm by 60 µm whereas the rounder form measured 45 µm by 37 µm. Use the pulldown boxes to identify each picture: | View Page |
| A 65 year old Asian female presented to the emergency room exhibiting severe abdominal pain, fever and diarrhea. Examination revealed an enlarged liver that was tender to the touch. Patient history revealed that the woman worked in a fish processing plant for years prior to moving to the United States. Her diet was heavy in raw fish. Stool and duodenal contents were collected and sent to the laboratory for cultures and parasite examination. The cultures were unremarkable. This suspicious form was seen in both specimen types. It measures 27 µm by 14 µm. This patient is most likely suffering from: | View Page |
| A 17 year old female went to her doctor complaining of diarrhea. With the exception of seasonal allergies, she was in relatively good health. Patient history was unremarkable.
