| molecular markers for gyrodactylids (gyrodactylidae: monogenea) from five fish families (teleostei). | thirty-one gyrodactylid species from five families of freshwater fish were examined and variable region v4 of the 18s small subunit ribosomal rna gene and ribosomal rna internal transcribed spacers its1 and its2 were sequenced. both the v4 region and spacers its1 and its2 proved useful for gyrodactylid diagnosis. sequences of these fragments exhibited interspecific variations and allowed clear determination at the species level. in some cases, the length of the its1 pcr fragment provided useful ... | 2001 | 11336756 |
| parasite assemblages of european bitterling (rhodeus amarus), composition and effects of habitat type and host body size. | parasite community composition of european bitterling (rhodeus amarus), the only bitterling species occurring on the european continent, was investigated in 16 different localities from four european sea drainages during 1998-2007. a total of 41 species of metazoan parasites was identified. nine parasite species are new records for european bitterling, namely dactylogyrus rarissimus, d. suecicus, d. yinwenyingae, gyrodactylus vimbi, sphaerostomum globiporum, petasiger sp., paryphostomum radiatum ... | 2008 | 18180954 |
| monogenean assemblages and the apparent transmission capability of monogeneans between related fish species: an experimental study. | gyrodactylid monogeneans are considered to be the most invasive fish parasites. they are omnipresent on teleost fishes and host change might play a crucial role in their biology. in the present study, related fish species were kept in single- or mixed-species groups to test the ability of gyrodactylus species to change their host fish under experimental conditions. the first group included two percid fish species, perch perca fluviatilis l. and ruffe gymnocephalus cernuus (l.), and the second gr ... | 2008 | 18288490 |
