We study the properties of quark-antiquark interactions in the Quark-Gluon Plasma at moderate temperatures, T {approx_equal} 1-2 Tc, within a Brueckner-type many-body approach. The quark-antiquark T-matrix, including both color-singlet and -octet channels, and corresponding quark self-energies are evaluated self-consistently. We find that light mesonic states persist as resonances in the Quark-Gluon Plasma up to temperatures T {approx_equal} 1.75Tc and fermionic quasiparticles acquire masses of up to {approx}150 MeV and widths of around {approx}200 MeV.
