      abstract     = {The effects of sulfadiazine (SD), one of the generally used
                      antibiotics was studied on bacteria-membrane mimetic model
                      systems consisting of pure
                      dipalmitoylphosphatidylethanolamine (DPPE) and
                      DPPE/dipalmitoylphosphatidylglycerol (DPPG) at 95/5, 80/20
                      and 50/50 DPPE/DPPG ratios by using differential scanning
                      calorimetry (DSC), simultaneous small- and wide-angle X-ray
                      scattering (SWAXS) and freeze-fracture technique. In the
                      presence of SD, varied between 10-3 and 1 SD/lipid molar
                      ratios, the 95/5 DPPE/DPPG system shows tendentious
                      destruction in the layer arrangement which is accompanied by
                      minor perturbations in the thermotropic behaviour. Moreover,
                      at this lipid composition the addition of SD results in the
                      formation of stacks of extremely extended flat bilayers.
                      Systems having a higher DPPG molar ratio exhibit complex and
                      diffuse morphologies. At 50/50 DPPE/DPPG ratio DPPG and SD
                      act together and form large spherical vesicles. The uniform
                      morphology is not accompanied by a regular lamellar
                      arrangement. The range of the SD/lipid ratio, where the SD
                      molecules are embedded into the lipid bilayers, extends to
                      about 10-1. Over this limit the separation of SD molecules
                      can be observed at all investigated DPPE/DPPG ratios.},
