F. donanaensis has been detected in this study in native and in
exotic turtles coexisting in Portil. Previously detection of the
same species in M. leprosa from Doñana (Hidalgo-Vila et al.,
2006), an area in which exotic turtles are not present, reveals
that the presence of these nematodes in exotic turtles has
resulted from the cross transmission of F. donanaensis from native
turtles.
