Figure. 4. Bacterial burden in peri-implant tissue.

Figure. 4

(A) Gram stain of peri-implant tissue (S. aureus dark purple, Red arrow: bacteria, Scale bar: 100 μm). (B) Bacterial CFU in local tissue three days and 7 days (C) after inoculation. Local tissue was collected, digested, diluted and plated on agar plate to count CFU, which was normalized by tissue weight. Results are presented from individual implants. (D) Infection rate was calculated at day 7 by dividing the number of infected tissue samples by total sample number.
