For insights into the environmental risk of<jats:italic>S. haematobium<\/jats:italic>transmission on Pemba Island, malacological surveys collecting<jats:italic>Bulinus globosus<\/jats:italic>and<jats:italic>B. nasutus<\/jats:italic>, two closely related potential intermediate hosts of<jats:italic>S. haematobium<\/jats:italic>were conducted across the island in November 2016. Of 1317<jats:italic>B. globosus<\/jats:italic>\/<jats:italic>B. nasutus<\/jats:italic>collected, seven<jats:italic>B. globosus<\/jats:italic>, identified through sequencing a DNA region of the mitochondrial cytochrome oxidase subunit 1 (<jats:italic>cox<\/jats:italic>1), were observed with patent infections assumed to be<jats:italic>S. haematobium<\/jats:italic>. However, when the collected cercariae were identified through sequencing a region of the<jats:italic>cox<\/jats:italic>1 and the nuclear internal transcribed spacer (ITS1 + 2), schistosomes from five of these<jats:italic>B. globosus<\/jats:italic>collected from a single locality were in fact<jats:italic>S. bovis<\/jats:italic>. The identified presence of<jats:italic>S. bovis<\/jats:italic>raises concerns for animal health on Pemba, and complicates future transmission monitoring of<jats:italic>S. haematobium<\/jats:italic>. These results show the pertinence for not only sensitive, but also species-specific markers to be used when identifying cercariae during transmission monitoring, and also provide the first molecular confirmation for<jats:italic>B. globosus<\/jats:italic>transmitting<jats:italic>S. bovis<\/jats:italic>in East Africa.<\/jats:p>","DOI":"10.1017\/s0031182018001154","type":"journal-article","created":{"date-parts":[[2018,8,8]],"date-time":"2018-08-08T08:12:50Z","timestamp":1533715970000},"page":"1727-1731","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":28,"title":["Occurrence of<i>Schistosoma bovis<\/i>on Pemba Island, Zanzibar: implications for urogenital schistosomiasis transmission monitoring"],"prefix":"10.1017","volume":"145","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4898-462X","authenticated-orcid":false,"given":"Tom","family":"Pennance","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaali M.","family":"Ame","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armour Khamis","family":"Amour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khamis Rashid","family":"Suleiman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fiona","family":"Allan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Rollinson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0930-9314","authenticated-orcid":false,"given":"Bonnie L.","family":"Webster","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2018,8,8]]},"reference":[{"key":"S0031182018001154_ref48","first-page":"427","article-title":"Recent work on schistosomes and snails in Kenya","volume":"35","author":"Teesdale","year":"1958","journal-title":"East African Medical Journal"},{"key":"S0031182018001154_ref17","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.1000571"},{"key":"S0031182018001154_ref10","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-308X(08)60426-1"},{"key":"S0031182018001154_ref38","first-page":"1","article-title":"Helminths in the induction of cancer II.
