Figure 2. Adherence of P. aeruginosa strains to unmodified and charge modified surfaces.

Figure 2

Wild type strains of Pseudomonas aeruginosa (PAO1 and PA14) and otopathogenic strains of P. aeruginosa (OPPA 8, 13, 15) were bound to unmodified, positive and negative charge modified plates. The plates were incubated for 30, 60, and 120 minutes, washed and the bacteria were enumerated by microscopy (bacteria/hpf). P-values represent statistical difference between unmodified and modified samples.
