The prevalence of <jats:italic>E. multilocularis<\/jats:italic> \nin foxes sampled during winter increased significantly from 47% in the urban to 67% in the adjacent recreational area, \nwhereas prevalence rates of other helminths were similar in both areas. Seasonal differences in the prevalence of <jats:italic>E. \nmultilocularis<\/jats:italic> were only found in urban subadult male foxes which were significantly less frequently infected in summer \nthan in winter. The distribution of the <jats:italic>Echinococcus<\/jats:italic> biomass, as expressed by worm numbers per fox was overdispersed \nin 133 infected foxes randomly sampled in winter. Ten of these foxes (8%) were infected with more than 10000 specimens \nand carried 72% of the total biomass of <jats:italic>E. multilocularis<\/jats:italic> (398653 worms). Prevalences did not differ significantly in these \nfoxes in regard to age and sex but worm burdens were significantly higher in subadult foxes as compared with adult foxes. \nIn voles (<jats:italic>Arvicola terrestris<\/jats:italic>) trapped in a city park of Z\u00fcrich, <jats:italic>E. multilocularis<\/jats:italic> metacestodes were identified by morphological \nexamination and by PCR. The prevalence was 20% among 60 rodents in 1997 and 9% among 75 rodents in 1998. \nProtoscoleces occurred in 2 of the cases from 1997. The possible risk for human infection is discussed with respect to the \nestablished urban <jats:italic>E. multilocularis<\/jats:italic> cycle.<\/jats:p>","DOI":"10.1017\/s0031182099005351","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:36:03Z","timestamp":1027776963000},"page":"135-142","source":"Crossref","is-referenced-by-count":293,"title":["High prevalence of <i>Echinococcus multilocularis<\/i> in urban red \nfoxes (<i>Vulpes vulpes<\/i>) and voles (<i>Arvicola terrestris<\/i>) in the \ncity of Z\u00fcrich, Switzerland"],"prefix":"10.1017","volume":"120","author":[{"given":"S.","family":"HOFER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"GLOOR","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"M\u00dcLLER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"MATHIS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"HEGGLIN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"DEPLAZES","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2000,2,1]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182099005351","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T19:23:23Z","timestamp":1554233003000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182099005351\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2000,2]]}},"alternative-id":["S0031182099005351"],"URL":"https:\/\/doi.org\/10.1017\/s0031182099005351","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,2]]}}}
