In order to improve the taxonomic knowledge on this parasite, studies of miracidial chemo-orientation as well as experimental infections of different snail species were conducted using strains of <jats:italic>T. ocellata<\/jats:italic> and <jats:italic>T. franki<\/jats:italic>. Both schistosomes exhibited a high intermediate host specificity. The miracidia clearly preferred the SCW (snail-conditioned water) of the respective natural intermediate host to SCW of other sympatric snail species. <jats:italic>T. ocellata<\/jats:italic> proved to be capable of infecting <jats:italic>Lymnaea stagnalis<\/jats:italic> and <jats:italic>Stagnicola palustris<\/jats:italic>, but could not develop in <jats:italic>Radix ovata<\/jats:italic> or <jats:italic>R. auricularia<\/jats:italic>. <jats:italic>T. franki<\/jats:italic> established an infection in specimens of <jats:italic>R. auricularia<\/jats:italic> and <jats:italic>R. ovata<\/jats:italic>, but not in <jats:italic>L. stagnalis<\/jats:italic> or <jats:italic>S. palustris<\/jats:italic>. The results imply that the intermediate host spectrum of <jats:italic>T. ocellata<\/jats:italic> is limited to <jats:italic>L. stagnalis<\/jats:italic> and <jats:italic>S. palustris.<\/jats:italic> Findings of <jats:italic>T. ocellata <\/jats:italic>(or <jats:italic>Cercaria ocellata<\/jats:italic>) that originated from snails of the genus <jats:italic>Radix<\/jats:italic> are likely to have actually belonged to species such as <jats:italic>T. franki <\/jats:italic>or <jats:italic>T. regenti<\/jats:italic>. The assumption that <jats:italic>T. szidati<\/jats:italic> is synonymous to <jats:italic>T. ocellata<\/jats:italic> is also discussed.<\/jats:p>","DOI":"10.1017\/s0031182001008101","type":"journal-article","created":{"date-parts":[[2002,10,30]],"date-time":"2002-10-30T10:58:26Z","timestamp":1035975506000},"page":"67-70","source":"Crossref","is-referenced-by-count":35,"title":["Investigations of intermediate host specificity help to elucidate the taxonomic status of <i>Trichobilharzia ocellata<\/i> (Digenea: Schistosomatidae)"],"prefix":"10.1017","volume":"123","author":[{"given":"S.","family":"KOCK","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2001,7,23]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182001008101","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T15:49:27Z","timestamp":1554306567000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182001008101\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,7]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2001,7]]}},"alternative-id":["S0031182001008101"],"URL":"https:\/\/doi.org\/10.1017\/s0031182001008101","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001,7]]}}}
