What causes Cyclospora infection?

Cyclospora cayetanensis is a parasite which passes between the outside environment and humans during its life cycle. It exists for long times in nature in a highly stable form called an oocyst. The oocyst for can resist extreme temperatures and is not killed by usual concentrations of formalin or chlorine. When temperatures warm, the oocyst matures in a process called sporulation, producing forms known as sporozoites. When the sporozoites are inadvertently ingested by a human, they begin to reproduce, eventually forming new oocysts that are excreted in feces, starting the cycle all over again.
