Aug 10th – Cyclospora cayetanensis is a protozoan that causes disease in humans, and perhaps primates. It has been linked in the United States to fecally contaminated imported produce, and was virtually unknown before about 1990, but has been on the rise since. The health risk associated with the disease is usually confined to adult foreigners visiting regions where the species is endemic and acquiring the infection; consequently, C. cayetanensis is a cause of “traveler’s diarrhea”.
