From: Elucidating bacterial adhesion to mucosal surface by an original AFM approach
Deadhesion work for interactions between A. salmonicida and Y. ruckeri and proximal intestinal mucins of Atlantic salmon before and after neuraminidase-treatment of mucins. Three experimental parallels were performed with both pathogens, using three different mucin-coated surfaces and three bacterial probes. The analysis is based on 900 force-distance curves recorded on each mucin-coated surface. The histograms display the frequency (%) of magnitudes of deadhesion work (nN nm) for the interactions measured with AFM force spectroscopy. Inset; representative force-distance curves obtained when quantifying the interactions between the bacterial probes and the proximal intestinal mucin samples
