We investigate two-loop gluino corrections to the effective Lagrangian for b{yields}s+{gamma}(g) in the minimal supersymmetric extension of the standard model (MSSM) at large tan{beta}, including the contributions in which quark flavor change is mediated by charginos. Using the translation invariance of loop momenta and the Ward-Takahashi identities that are required by the SU(3){sub c}xU(1){sub em} gauge invariance, we simplify our expressions to concise forms. As an example, we discuss two-loop gluino corrections to the CP asymmetry of inclusive B{yields}X{sub s}{gamma} decay in CP violating MSSM.
