Cattle are known to be significant reservoirs of C. parvum, but transmission routes are complex and recent studies have implicated the potential role of wildlife in parasite transmission to cattle and water sources. On the Orkney Isles, high densities of Greylag geese (Anser anser) cause widespread faecal contamination of cattle pastures, where cryptosporidiosis is known to be the main cause of neonatal calf diarrhoea and Cryptosporidium contamination frequently occurs in two reservoirs supplying Mainland Orkney\u2019s public water. This study aimed to determine the Cryptosporidium species and subtypes present in geese and calves co-grazing on four farms surrounding two reservoirs on Mainland Orkney. Results indicated a high level of C. parvum prevalence in calves, geese and water samples. gp60 analysis illustrated that higher genotypic diversity was present in the goose population compared with calves, but did not yield sequence results for any of the water samples. It can be concluded that the high levels of C. parvum evident in calves, geese and water samples tested represents a significant risk to water quality and public health.<\/jats:p>","DOI":"10.3390\/microorganisms7110513","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"513","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Cryptosporidium Prevalence in Calves and Geese Co-Grazing on Four Livestock Farms Surrounding Two Reservoirs Supplying Public Water to Mainland Orkney, Scotland"],"prefix":"10.3390","volume":"7","author":[{"given":"Beth","family":"Wells","sequence":"first","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire","family":"Paton","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross","family":"Bacchetti","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hannah","family":"Shaw","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Stewart","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Plowman","sequence":"additional","affiliation":[{"name":"Scottish Natural Heritage, 54-56 Junction Road, Kirkwall, Orkney KW15 1AG, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5902-4136","authenticated-orcid":false,"given":"Frank","family":"Katzer","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabeth A","family":"Innes","sequence":"additional","affiliation":[{"name":"Moredun Research Institute, Pentlands Science Park, Penicuik, Midlothian EH26 0PZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/00480169.2012.731681","article-title":"Clinical and subclinical infections with Cryptosporidium in animals","volume":"61","author":"Santin","year":"2013","journal-title":"N Z Vet.
