Brightfield images showing typical biofilms.

<p>This example was cultured from inoculum from a clinically low-fluorescent, low-bleeding on marginal probing participant. <b>A:</b> anaerobic biofilm grown with artificial saliva medium and 10% serum; <b>B:</b> anaerobic biofilm grown with artificial saliva medium and 0.2% sucrose; <b>C:</b> aerobic biofilm grown with artificial saliva medium and 0.2% sucrose. <b>I:</b> at time point 0 (one hour after inoculation); <b>II:</b> after 6 hours of biofilm growth; <b>III:</b> after 12 hours of biofilm growth.
