We discuss the role of quarks and baryons near the QCD phase transition. The former is modelled in the spirit of PNJL model, while the latter is splitted into two classes: 'stringy' and 'non-stringy' baryons. We represent the non-stringy baryons by a sum over the resonance on equal footing, and obtain the density of states of stringy baryons from string inspired model at finite-T. Our model produce a rise and fall of baryonic contribution to the susceptibility, which is in qualitative agreement with lattice results. We also discuss the chiral effect on the baryonic mass and susceptibility.
