“…A few reports have described the presence of Cyclospora oocysts in the feces of chickens (70,168), ducks (197), and dogs (194). Other studies surveying feces of cattle, horses, pigs, goats, dogs, cats, guinea pigs, turkeys, chickens, ducks, and pigeons did not find Cyclospora in these animal species (27,62,141).…”

“…The role of other animal species as reservoirs or intermediary hosts has been examined, with conflicting results. Cyclospora oocysts have been found in feces of chickens (37,62,70), ducks (62,197), and dogs (27,37,62,194) collected in countries where Cyclospora is endemic (27,62,63). However, attempts to experimentally infect a variety of animals (63) and humans (5) have been unsuccessful.…”

SUMMARY The coccidian parasite Cyclospora cayetanensis is recognized as an emerging pathogen that causes protracted diarrhea in humans. The first cases of Cyclospora infection were reported in the late 1970s and were observed among expatriates and travelers in regions where infections are endemic. Since then, Cyclospora has been considered a cause of traveler's diarrhea. Epidemiological investigations were reported and examined in areas of endemicity even before the true identity of Cyclospora was elucidated. Cyclospora was fully characterized in the early 1990s, but it was not until the 1995 Cyclospora outbreak in the United States and Canada that it caught the attention of the public and physicians. The biology, clinical presentation, epidemiology, diagnosis, treatment, and control of cyclosporiasis are reviewed, with a focus on diagnostic assays currently being used for clinical and environmental samples. Challenges and limitations in working with Cyclospora are also discussed.

“…Contact with animals is considered a risk factor for infection in Guatemala (Bern et al, 1999), Peru (Bern et al, 2002), Jordan (Nimri, 2003), Nepal (Sherchand et al, 1999(Sherchand et al, , 2001Bhandari et al, 2015) and Egypt (el-Karamany et al, 2005). Oocystsresembling those of C. cayetanensis have been identified, using conventional methods, in the feces of several animals including ducks (Zerpa et al, 1995), chickens (García-López et al, 1996;Sherchand et al, 1999Sherchand et al, , 2001), mice and rats (Sherchand et al, 2001), dogs (Yai et al, 1997;Sherchand et al, 2001), and birds (Perez Cordon et al, 2009). Cyclospora-like oocysts were observed in feces of animals (carnivores, artiodactyla, and nonhuman primates) from a Spanish zoological garden (Perez Cordon et al, 2008).…”

“…En contraste con estos estudios, en Haití, el parásito no se observó en 327 animales domésticos, incluyendo vacas, caballos, cabras, cerdos, gatos, cobayos, patos, pavos, pollos y palomas (102). En Brasil, se identificó el parásito en dos perros (98), pero no se identificó en 140 perros de la misma región (103).…”

Cyclospora cayetanensis es un protozoo apicomplexa que ha emergido como un patógeno importante causante de diarrea endémica y epidémica en el mundo. En los países industrializados, el parásito se ha reconocido como agente causal de diversas epidemias asociadas, principalmente, con alimentos importados de áreas endémicas. En los países en vías de desarrollo, la ciclosporosis humana está ampliamente distribuida y, en la población general, se han descrito tasas de infección que varían de 0 % a 41,6 %. Sin embargo, la epidemiologia, biología y ecología de C. cayetanensis permanecen poco conocidas. Su ciclo de vida no está totalmente caracterizado y parece requerir un huésped único, el humano, para completarse. El papel que los animales puedan desempeñar como reservorios naturales del parásito permanece sin determinar. Se tiene poca información sobre la distribución ambiental de C. cayetanensis y los vehículos de transmisión del ambiente a los humanos. El agua, los alimentos y los suelos contaminados pueden actuar como vehículos de diseminación del coccidio. Permanecen incertidumbres significativas sobre el parásito, que reflejan la necesidad de continuar los esfuerzos de investigación en diversas áreas, incluyendo su biología básica y distribución ambiental.

Cyclospora cayetanensis: biology, environmental distribution and transfer Cyclospora cayetanensis is an apicomplexan protozoan that has emerged as an important pathogen causing endemic or epidemic diarrheal disease worldwide. In industrialized countries, the parasite has been recognized as the causative agent of several outbreaks of diarrheal illness mostly associated with produce imported from endemic areas. In developing countries, human cyclosporosis is widely distributed. Infection rates from 0% to 41.6% have been described in the general population. However, the epidemiology, biology, and ecology of C. cayetanensis are not fully understood. The life cycle is not completely characterized, although it appears to require a single human host to be accomplished. The role of animals as natural reservoirs of the parasite remains to be determined. Little information is available concerning the environmental distribution and vehicles of transmission of C. cayetanensis. Contaminated water, foods or soil can be vehicles of spread of the parasite. The significant uncertainties that remain in the knowledge of C. cayetanensis highlight the need for continuing research in several areas, including its basic biology and environmental distribution.
