In recent years, human cyclosporiasis has emerged as an important infection, with large outbreaks in the United States and Canada. Understanding the biology and epidemiology of Cyclospora has been difficult and slow and has been complicated by not knowing the pathogen s origins, animal reservoirs (if any), and relationship to other coccidian parasites. This report provides morphologic and molec...

354 Letters To the Editor: The organism now named Cyclospora cayetanensis was first recognized as a cause of human illness in 1977. For several years, as its taxonomy was deliberated , it was referred to as " cyanobacterium-, or coccidia-like bodies " (CLBs), or considered to be blue-green algae. In 1993, C. cayetanensis was reported to be a protozoan parasite, a coccidian member of the family ...

Cyclospora cayetanensis is a cause of prolonged diarrhoea, mainly in travellers. Laboratory diagnosis may be achieved by a number of methods such as the staining of faecal smears by the modified Ziehl-Neelsen (ZN) technique. Safer methods using this technique have been described for the staining of acid fast bacilli and cryptosporidia by replacing the phenol content of the carbol fuschin stain ...

Recent studies suggest the involvement of water in the epidemiology of Cyclospora cayetanensis and some microsporidia. A total of 223 samples from four drinking water treatment plants (DWTPs), seven wastewater treatment plants (WWTPs), and six locations of influence (LI) on four river basins from Madrid, Spain, were analyzed from spring 2008 to winter 2009. Microsporidia were detected in 49% of...

Cylospora cayetanensis, an emerging parasitic pathogen of human is being increasingly recognized throughout the world, however the means of transmission and the possibility of a reservoir host remain an enigma. A longitudinal study on cyclosporiasis in different parts of Nepal was carried out from April, 1995 until November, 2000. Fecal specimens were collected from symptomatic and asymptomatic...
