  Isomorph theory is employed in order to establish a mapping between the
bridge function of Coulomb and Yukawa one-component plasmas. Within an exact
invariance ansatz for the bridge functions and by capitalizing on the
availability of simulation-extracted Coulomb bridge functions, an analytical
Yukawa bridge function is derived which is inserted into the integral theory
framework. In spite of its simplicity and computational speed, the proposed
integral approach exhibits an excellent agreement with computer simulations of
dense Yukawa liquids without invoking adjustable parameters.
