  In this paper, we study the existence and uniqueness of mild solution for a
stochastic neutral partial functional integro-differential equation with delay
in a Hilbert space driven by a fractional Brownian motion and with
non-deterministic diffusion coefficient. We suppose that the linear part has a
resolvent operator. We also establish a sufficient condition for the existence
of the density of a function of the solution. An example is provided to
illustrate the results of this work
