RESEARCH Open Access The effect of octopaminergic compounds on the behaviour and transmission of Gyrodactylus
Background: The high transmission potential of species belonging to the monogenean parasite genus Gyrodactylus, coupled with their high fecundity, allows them to rapidly colonise new hosts and to increase in number. One gyrodactylid, Gyrodactylus salaris Malmberg, 1957, has been responsible for deva...
