Anotace

V originále

Anacanthorus is a Neotropical genus of gill monogeneans which are known to parasitize Characiform fishes, mainly the members of Serrasalmidae and some species of Characidae. The host-parasite associations between the serrasalmids and the Anacanthorus parasites have been known for a long time. The family Serrasalmidae is restricted to South America and currently consists of 95 species representing 16 genera, which are commonly divided in three main clades (i.e. pacu, true piranhas and a Myleus-like pacus clade). Further, the majority of serrasalmids (69) are distributed in Brazil. To date there are 73 valid species of Anacanthorus, and more than half of the species (37) were described from serrasalmids. According to literature, some species within this host-parasite system can be considered generalists (e.g. A. jegui and A. mesocondylus, which can be found in 6 different hosts), but most of them (22) are strictly specialists (parasitizing a single host species). Previous studies have demonstrated that monogeneans may provide good model for the study of host-parasite coevolution, therefore the main aim of this study is to reconstruct phylogenies for the hosts (serrasalmids) and their monogenean parasites (Anacanthorus) to investigate host-parasite coevolution and with the use of molecular analyses (based on the sequences of 28S rDNA) to define the systematic position of these monogeneans among other dactylogyrids. During our parasitological surveys carried out from 2015-2016 in different Brazilian river basins, eleven species of serrasalmids (including representatives of the three clades), were dissected. Molecular identification of fish species was performed using cytochrome b gene. Nineteen species (8 unidentified) of Anacanthorus were found and the phylogenetic relationships of some of these species were assessed using molecular sequences. Preliminary results of our analyses are presented.
