An anxious but healthy 32-year-old male physician presented to the family medicine clinic with a sample of suspected parasites from his stools, which had been retrieved from the toilet that same day. Having a background in clinical health sciences, he had a number of questions and concerns regarding the stool contents and intestinal parasites. Upon questioning, the patient reported traveling to India 2 years before. Soon after the trip he experienced an episode of extreme gastrointestinal upset involving nausea and diarrhea that lasted 2 weeks before resolving. He also had a long-standing history of loose stools and difficulty gaining and maintaining weight. In addition, the patient noted that he had eaten Chinese food the night before.
The patient was otherwise asymptomatic, and results of physical examination were normal. After examining the stool samples (Figures 1 and 2), and in the light of his travel history and symptoms, a possible diagnosis of hookworms was considered. The sample was sent to the microbiology laboratory for further analysis.
Later that day, the microbiology physician called to report positive identification of Vigna radiata (previously known as Phaseolus aureus) in the stool sample.
