Figure 3. Bioluminescence imaging of juvenile catfish after immersion exposure to wild type E. ictaluri.

Figure 3

Fish were challenged with E. ictaluri mutants as described in the virulence trial, and at 4 weeks post-vaccination they were challenged with bioluminescent wild type E. ictaluri. A, BLI imaging of catfish. B, Total photon emissions from each fish. Each data point represents the mean photon emissions from four fish. Star indicates significant difference between the E. ictaluri mutants and wild type.
