A major reason for the high biodiversity of parasites is considered to be adaptive speciation after host-switching. Central to such a speciation process are genes which show differing fitnesses in the old and new hosts. Individual genomic regions, even without complete isolation of the diverging populations, cannot be freely exchanged when such genes are present. The swimbladder nematode Anguillicola crassus, which originally parasitized the Asian eel Anguilla japonica, was first reported from Europe in the early 1980s where it showed increased pathogenicity in its new European host An...
