Cyclospora cayetanensis is a unicellular parasite belonging to the Protista kingdom and is classified as a coccidian, a type of microorganism that produces oocysts. First identified in 1979, Cyclospora cayetanensis gained attention for its role in causing gastrointestinal illness in humans, particularly in tropical and subtropical regions. The parasite is typically associated with the consumption of contaminated fresh produce, particularly berries, lettuce, and herbs. Outbreaks have been reported in various countries, often linked to imported food items, highlighting the importance of food safety and public health measures. The oocysts of Cyclospora cayetanensis can survive in the environment for extended periods, complicating efforts to control its spread. Research into this bio marker continues to expand, focusing on its transmission dynamics, pathogenicity, and the development of effective diagnostic methods.

Elevated levels of Cyclospora cayetanensis may indicate an active infection, commonly associated with foodborne illness linked to contaminated produce, especially berries and salad greens. This can present with gastrointestinal symptoms such as diarrhea, abdominal cramps, and nausea. A higher level may suggest recent exposure or consumption of contaminated food sources. Conversely, low levels of Cyclospora cayetanensis typically indicate the absence of such an infection, with the individual likely not having been exposed to the pathogen. Maintaining low levels can reflect effective hygiene and food safety practices, though it is essential to consider other environmental and dietary factors that may influence gut health.

Cyclospora cayetanensis is included in the Gut Zoomer panel, which assesses a broad spectrum of gut health markers, including various pathogens and microbial imbalances. This bio marker is essential for identifying the presence of this parasite, which can cause gastrointestinal infections and disrupt overall gut function. By detecting Cyclospora cayetanensis, practitioners can better understand potential sources of gastrointestinal distress and tailor interventions to restore balance and improve gut health.
