An equation of state (EOS) for uniform nuclear matter is constructed at zero and finite temperatures with the variational method starting from a realistic nuclear Hamiltonian composed of the AV18 two-body potential and the UIX three-nucleon interaction (TNI). The two-body energy is calculated with a Jastrow wave function, and the TNI energy with the Fermi-gas wave function. In this calculation, the Fujita-Miyazawa (FM) 2{pi}-exchange term of the TNI energy is positive for symmetric nuclear matter. By taking into account the correlation between nucleons perturbatively, the expectation value of the FM term is modified to be negative in the low density region.
