SEM-images of P. stuartii NK adhesion onto HeLa-M cells. Subconfluent HeLa-M monolayers were infected with P. stuartii NK at a ratio of 50 bacterial cells to 1 eukaryotic cell at 37°C. (a) Control (HeLa-M cells were not infected with bacteria); (b) 30 minutes of postinfection with P. stuartii NK; (c) 60 minutes of postinfection with P. stuartii NK. Magnification 15. 00 K X.
