The incidence ofCyclospora cayetanensisin stool samples submitted to a district general hospital

Abstract

SUMMARYCyclospora cayetanensis is the cause of a prolonged diarrhoeal syndrome. In the UK most cases are seen in travellers who have returned from countries in which the organism is endemic. The purpose of this investigation was to determine the incidence of C. cayetanensis in stool samples submitted to a district general hospital. A total of 6151 stools from 5374 different patients were screened for the presence of C. cayetanensis over a 1-year period using the modified Ziehl-Neelsen technique. Oocysts of C. cayetanensis were found in 7 stools (0 1 %) from 4 patients (007 %). All four patients were adult travellers who had visited countries in which C. cayetanensis is known to be endemic. In the population of this study, C. cayetanensis was found to be a rare cause of diarrhoea. Although C. cayetanensis infection should be considered in individuals of all ages who have lived in, or have travelled to endemic areas, there is no need to screen stool samples for the organism in those without such a travel history.

Cyclospora infection in five immunocompetent patients in a Turkish university hospital

“…It has caused a number of sporadic cases and epidemic outbreaks of diarrhoeal illness. The majority of the isolates from humans have been from residents of developing countries or from travellers returning from Haiti, Mexico, Guatemala, Puerto Rico, Morocco, Pakistan and India (Clarke & McIntyre, 1996;Pollok et al, 1992).…”

Cyclospora cayetanensis

“…Unlike the US and Canada, most cases of cyclosporiasis in Europe and Australia have been linked with international travel to endemic areas. Cyclosporiasis has been reported in Spain, France, Belgium, Italy, Germany, Greece, United Kingdom, Ireland, Sweden, Switzerland, The Netherlands, New Zealand, and Australia (Shlim et al, 1991;Clarke et al, 1996;Drenaggi et al, 1998;Puente et al, 2006;Bourée et al, 2006Bourée et al, , 2007Ortega et al, 2010). Outbreaks of cyclosporiasis have also been reported in travelers from Spain (Puente et al, 2006), Poland (Bednarska et al, 2015) and the United Kingdom (Nichols et al, 2015) (Table 2).…”

“…Young children, in the first five years of age, are more likely to develop clinical symptoms (Hoge et al, 1995;Madico et al, 1997;Sherchand et al 1999Sherchand et al , 2001Chacín-Bonilla et al, 2001;Bern et al, 2002). Among resident foreigners and expatriates, the disease is common (Clarke and McIntyre, 1996;Drenaggi et al, 1998;Shields et al, 2003a;Puente et al, 2006;Bourée et al, 2006Bourée et al, , 2007 and outbreaks have been reported (Shlim et al, 1991;Hoge et al, 1993;Rabold et al, 1994;Blans et al, 2005;Puente et al, 2006;Bednarska et al, 2015;Nichols, 2015) (Table 2). Among HIV-infected patients, Cyclospora is an important cause of diarrhea (Chacin-Bonilla, 2010).…”

Cyclospora cayetanensis, um novo protozoário a ser pesquisado

“…A infecção é observada em indivíduos de todas as idades, imunodeprimidos e imunocompetentes, que vivem ou viajam para áreas endêmicas 5 , coincidindo, principalmente, com a primavera e o verão 3 .…”
