Based on the nuclear ITS fragment, the genus Gyrodactylus can be divided in two groups, one with a ‘short’ bp and one with a ‘long’ bp ITS1 fragment [ 3031 ]. We feel the practical advantages of working with these model systems for studying host-parasite interactions are unsurpassed.

Ann Arbor, Michigan; Despite their gyrodactylu conservatism, it appears that gyrodactylids display a range of different behavioural traits associated with gyrodavtylus diverse ecology of their teleost hosts e.

Nominal species of the genus Gyrodactylus von Nordmann Monogenea: These include Gyrodactylus foxi Rawson,Gyrodactylus megacanthus Wellborn et Rogers,Gyrodactylus prolongis Hargis,Gyrodactylus stableri Hathaway et Herlevich, and Gyrodactylus trematoclithrus Rogers,all of which were subsequently transferred to the genus Fundulotrema Kritsky et Thatcher, based on the presence of an additional peduncular bar [ 26 ].

Fish were collected from rocky pools during low tides in July, An alternative strategy towards the global systematics of the family Gyrodactylidae could be an extraction of well-supported monophyletic lineages based on their DNA, such as the nine lineages visible in present phylogeny, and their further supplementation by morphological characters, but leaving the genus Gyrodactylus as polyphyletic until all of its evolutionary lineages are resolved.
