Image: Mixed-culture biofilm

Description: Scanning electron micrograph of mixed-culture biofilm, demonstrating in detail a spatially heterogeneous arrangement of bacterial cells and extracellular polymeric substances. The stainless steel (type 316) sample surface was incubated under high fluid shear stress and continuous flow conditions in the CDC Biofilm Reactor at 50 °C for 22h with high-heat skimmed milk powder reconstituted and preheated to 72 °C. Cocci and bacilli could be observed, although a direct correlation between bacterial morphological differences and clinical/radiographic findings was not established by means of SEM evaluation.
