After constructing a self-consistent first-order perturbation scheme, being suitable for all (sub-horizon and super-horizon) scales, for the concordance cosmological model and discrete presentation of matter sources in the recent paper arXiv:1509.03835, the next natural step consists in generalizing its approach to the case of extended models with extra perfect fluids and continuous presentation. In the given paper this suggesting itself generalization is made. Namely, we derive a single equation determining the scalar perturbation and covering the whole space as well as define the corresponding universal Yukawa interaction range.
