A 25 year old graduate student who had recently visited Finland and Japan for meetings was seen at an outpatient clinic. He complained of abdominal discomfort, fever, diarrhea. A stool sample was requested for parasite and enteric pathogen examination. A wet mount of the stool sample was positive for heminth eggs and bacterial culture was negative for pathogenic bacteria. Small flask shaped eggs with distinct shoulders and larger operculated eggs were found in the wet mount. 1) What intestinal parasites caused the patients infections (specify type of helminth)? 2) How did the patient acquire the infections? (what was the source of infection?). 3) What part of the parasite life cycle is important for transmission of both parasites? 4) What effect can both parasites have on the host? 5) How are the infections treated?
