  In this paper we give an electrically charged traversable wormhole solution
for the Einstein-Maxwell-dilaton theory when the dilaton is a phantom field,
i.e. it has flipped sign kinetic term appearing in the action. In the limit
when the charge is zero, we recover the anti-Fisher solution, which can be
reduced to the Bronnikov-Ellis solution under certain choices of integration
constants. The equations of motion of this theory share the same S-duality
invariance of string theory, so the electrically charged solution is rotated
into the magnetically charged one by applying such transformations. The scalar
field is topological, so we compute its topological charge, and discuss that
under appropriate boundary conditions we can have a lump, a kink, or an
anti-kink profile. We determine the position of the throat, and show the
embedding diagram of the wormhole. As a physical application, we apply the
Gauss-Bonnet theorem to compute the deflection angle of a light-ray that passes
close to the wormhole.
