AB Cyclospora  cayetanensis  is  a  coccidian  parasite  that  causes  acute  or  chronic,  food-  and  waterborne  diarrhea  in  both  immunocompetent  and  immunocompromised  hosts.  Cyclospora  is  a  distinct  protozoan  genus  phylogenetically  related  to  other  coccidian  parasites,  including  Cryptosporidium,  Cystoisospora,  Toxoplasma,  and  Sarcocystis.  Initially  described  in  1979  as  cyanobacteria-like  (blue-green  algae)  bodies  in  the  stools  of  patients  in  Papua  New  Guinea  with  prolonged  diarrhea,  anorexia,  and  fatigue,  Cyclospora  species  are  now  known  to  be  ubiquitous,  infecting  a  variety  of  animals,  birds,  reptiles,  insectivores,  and  rodents.  However,  C  cayetanensis  is  the  only  species  that  is  known  to  infect  humans,  and  the  role  of  animals  as  a  natural  reservoir  is  uncertain.
