In this paper, we employ the equation of state (EOS) of the quasiparticle model proposed in A. M. Zhao , Mod. Phys. Lett. A 25, 47 (2010)MPLAEQ0217-732310.1142/S0217732310031361] which incorporates the effect of vacuum negative pressure to study the properties of quark stars. In our model the EOS has the correct behavior required by QCD in the small and large μ limit. We employ this EOS to calculate the mass-radii relation and mass-energy density relation of quark stars. Our results are found to be consistent with the most recent astronomical observations.
