Recent evidence from mixed infections has shown that <jats:italic>Schistosoma mansoni<\/jats:italic> males can \ndisplace <jats:italic>S. intercalatum<\/jats:italic> males from their homologous partners, but no information exists about the existence of similar \nphenomena within a single schistosome species. Here, we determine whether male <jats:italic>S. mansoni<\/jats:italic> can displace males of the \nsame species from pre-formed pairs <jats:italic>in vivo<\/jats:italic>. The availability of clear-cut genetic markers of drug resistance in schistosomes \nwas exploited to show that hycanthone sensitive <jats:italic>S. mansoni<\/jats:italic> males can displace homospecific hycanthone resistant males \nfrom pre-formed pairs and <jats:italic>vice versa<\/jats:italic>. The frequency of changes is dependent on the magnitude of the excess single males \ncompeting with paired worms. The possible mechanics and the biological significance of mate changing are discussed.<\/jats:p>","DOI":"10.1017\/s0031182099005685","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:30:22Z","timestamp":1027762222000},"page":"495-500","source":"Crossref","is-referenced-by-count":15,"title":["Changes of mate occur in <i>Schistosoma mansoni<\/i>"],"prefix":"10.1017","volume":"120","author":[{"given":"L.","family":"PICA-MATTOCCIA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"MORONI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.
