Genes predicted to contribute to EPS biosynthesis that were significantly (P < 0.05) upregulated during biofilm growth (red bars) relative to planktonic growth (blue bars). The bacteria were grown as biofilms or in broth (planktonic) and samples taken at 3, 5 and 7 days for analysis by qRT-PCR from H. somni 2336 (left) or 129Pt (right). Fourteen of 19 genes were significantly upregulated in 2336, whereas only 5 genes were upregulated (predominately at 7 days) in 129Pt. The data were expressed as the means and SDs of three independent experiments performed in triplicate.
