Figure 2From: Gene expression profile and pathogenicity of biofilm-forming Prevotella intermedia strain 17Cell surface structures of Prevotella intermedia strains 17 and 17-2. Scanning electron micrographs showing the surface structures of Prevotella intermedia strains 17 and 17-2. The specimen was prepared from a colony of each strain grown on a blood agar plate. Strain 17 had dense meshwork-like structures surrounding the cell surfaces (A), but strain 17-2 lacked this phenotype (B). Bars = 2 μm.Back to article page
