| sphaeridiotrema globulus and sphaeridiotrema pseudoglobulus (digenea): species differentiation based on mtdna (barcode) and partial lsu-rdna sequences. | flukes belonging to sphaeridiotrema are important parasites of waterfowl, and 2 morphologically similar species sphaeridiotrema globulus and sphaeridiotrema pseudoglobulus, have been implicated in waterfowl mortality in north america. cytochrome oxidase i (barcode region) and partial lsu-rdna sequences from specimens of s. globulus and s. pseudoglobulus, obtained from naturally and experimentally infected hosts from new jersey and quebec, respectively, confirmed that these species were distinct. ... | 2011 | 21671715 |
