We derive the string representation of the Abelian Higgs theory in whi
ch dyons are condensed. It happens that in such a representation the t
opological interaction exists in the expectation value of the Wilson l
oop. Due to this interaction the dynamics of the string spanned on the
Wilson loop is nontrivial. (C) 1998 American Institute of Physics. [S
