Figure 2. Lack of correlation between culture status of each chronic OME specimen and quantity of IHF (Panel A) or HU (Panel B) as determined by immunoblot assay.

Figure 2.

Caption: Of 13 samples that yielded negative culture results, all 13 were positive for the DNABII proteins IHF and HU by quantitative immunoblot assay, as depicted by the blue circles. Red squares indicate the concentration of IHF or HU detected by quantitative immunoblot in the 24 specimens that yielded positive culture results. White squares depict specimens wherein the quantitative immunoblot assay yielded zero IHF or HU, but positive culture results for bacteria or yeast were obtained. No significant difference in quantity of either IHF or HU was calculated between specimens that were culture-positive versus those that were culture-negative. In sum, DNABII proteins were shown to be present by objective immunoblot assay even in the 13 specimens that had been deemed culture-negative.
