Cyclospora species - A new protozoan pathogen of humans.

Ortega and colleagues identified a novel parasite resembling C. muris in the feces of Peruvian patients and 2 U.S. patients, with symptoms resembling those of infections with Cryptosporidium. The parasite infected both immunocompetent and immunocompromised hosts, but stained parasitic photos and electron microscope images revealed a parasite distinct from Cryptosporidium.
