Attachment ofSalmonella typhimurium andListeria monocytogenes to glass as affected by surface film thickness, cell density, and bacterial motility

With equal cell densities, surface film thickness did not influence the numbers ofSalmonella typhimurium andListeria monocytogenes cells which attached to glass. MotileL. monocytogenes cells had a greater cell surface charge and generally attached in higher numbers than non-motile cells.
