Cyclospora Stain, Feces
Use
The Cyclospora Stain test aids in identifying Cyclospora cayetanensis as a causative agent of infectious gastroenteritis. Cyclospora cayetanensis is an apicomplexan protozoan parasite that can cause severe watery diarrhea, anorexia, malaise, and weight loss, particularly in immunocompromised individuals. This infection is transmitted via ingestion of contaminated food or water, and is endemic in parts of Asia, India, Southeast Asia, and Latin America. Without treatment, symptoms may persist for weeks, often requiring detection of oocysts for diagnosis.
Special Instructions
Not provided.
Limitations
The test uses modified safranin stain to detect Cyclospora cayetanensis oocysts, offering higher sensitivity compared to traditional acid-fast staining. However, the full spectrum of disease and extent of asymptomatic carriage are not entirely known. Moreover, Cryptosporidium oocysts are not reliably stained by this method, necessitating alternative testing methods for accurate detection where Cryptosporidium is suspected.
