Representative axial microCT scans of the experimental animals. Indicated bacteria were inoculated into the induced cholesteatomas on the right side (left side of image) and vehicle only was introduced into the left side (right side of image.) Note that OPPA8 and PA14 scans show increased cholesteatoma size and bony change compared to the non-piliated OPPA8 and the E. coli strain DH5α.
