As a preliminary step to our future work on the back reaction of a quantized field in an isotropic closed universe through its vacuum fluctuation, a massive scalar field is canonically quantized by taking full account of its coupling with the background universe and of the latter's topological (spherical or elliptic) nature. In terms of a vacuum state corresponding to our time-independent set of annihilation and creation operators, the most general formulae (without regularization) for the energy density and pressure are derived from two components of the stress-energy tensor. If the universe becomes static in particular, the formulate are reduced to a generalized version of Streeruwitz's ones in the Einstein universe. General formulate for various propagators of the quantized scalar field are also presented for future usefulness.
