Localisation and effect of SCPPPQ1 on the surface of P. gingivalis using SEM. (a) SEM micrographs of colloidal gold immunolabeled preparation showing the presence of gold particles (white dot) on bacteria from samples treated with + SCPPPQ1 (right) and their paucity in the negative control (left) at 20 min. (b) SEM micrographs showing the normal appearance of the bacterial surface in the negative control (left) and its disruption of the bacterial surface in samples treated with + SCPPPQ1 (right) at 20 min. Micrographs are representative from four different experiments.
