Ability of Corynebacterium spp. isolates to invade osteoblastic cells. (A) Internalization rates of Corynebacterium isolates in MG63 human osteoblasts according to bone and joint infection (BJI) evolution delay, in comparison with S. aureus 6850 (positive control) and S. aureus DU5883 strain, inactivated for the fnbA/B genes (FnBP, negative control). (B) Internalization rates of the Corynebacterium isolates in murine osteoblasts with functional (OB-β1fl/fl) or deficient (OB-β1−/−) expression of the integrin β1 subunit, in comparison with S. aureus 6850.
