AB  - In the present research, anatase nanoparticles as reinforcement and bacterial adhesion reducer were incorporated into a matrix of poly (methyl methacrylate) to obtain a composite material which combines adequate mechanical properties and high resistance to bacterial adhesion. The common pathological bacterial species, <i>Pseudomonas aeruginosa</i>, <i>Staphylococcus aureus</i> and <i>Klebsiella pneumonia</i> were selected for the bacterial adhesion tests. The surface properties of the composites were investigated and correlated to the adhesion behavior using nonlinear regression technique. The results showed that anatase nanoparticles improve the stiffness and the compressive strength of the PMMA matrix, however, the flexural strength is reduced noticeably. Nevertheless, a composite containing 10 wt.% of the anatase nanoparticles has the highest resistance to the bacterial adhesion and adequate flexural strength. Moreover, the regression analysis produced a common nonlinear model which excellently fits the experimental data for the different bacterial species using the contact angle, the nanoscale roughness and the microscale roughness as independent variables.
