Bacterial attachment to host tissues is the first step of infection. Blocking this bacterial binding provides novel potential to control infections. Cranberry is known to prevent the adhesion of E. coli, Helicobacter pylori, and mutans streptococci. This study carried out at the Department of Pharmaceutical Chemistry and the School of Public Health and Clinical Nutrition, University of Kuopio, was directed to binding and inhibitory activity of different berries and fruits against Neisseria meningitidis, which cause meningitis and septicemia. It adheres to human cells by pili which are long and flexible filamentous structures on the surface of bacteria.
