P. gingivalis adheres to and invades dermal fibroblasts. Dermal fibroblasts were seeded on a coverslip and incubated for 24 h. The cells were then stimulated with FITC-labeled P. gingivalis (MOI:100) for 6 h. F-actin was visualized by incubating the cells with Alexa Fluor® 594 phalloidin (TRITC) and the nuclei were visualized by counterstaining the cells with DAPI. Magnification is 60× (Olympus FluoviewTM FV1000, Germany).
