The possibility of large-scale adiabatic density fluctuations being generated by stress perturbations associated with transition phenomena in the early universe is investigated using Bardeen's gauge invariant formalism. Especially the effect of small change in the equation of state of background matter is estimated. It is shown that such effect is not important and the conclusion obtained by Press and Vishniac in the case of no change in the equation of state holds even if a small change in the equation of state of background matter coexists with stress perturbations. Namely the amplitudes of generated density fluctuations when they enter within the particle horizon are of the order of the strength of seed stress perturbations regardless of their type, isotropic or anisotropic.
