  • a All results are significant at a P value of <0.05 except where otherwise indicated. Confirmatory real-time PCR was performed with fhp and norB as detailed in the text. Values in parentheses represent gene expression ratios as determined by PCR.

  • b Ratio indicates no significant difference in gene expression.
