Detection of Edwardsiella Infections in Opsanus tau by Polymerase Chain Reaction

Opanus tau, the oyster toadfish, is an important laboratory animal used in hearing and balance research at the Marine Biological Laboratory. Baird et al observes Edwardsiella tarda, a member of the Enterobacteriaceae as the major cause of disease in toadfish held at the Marine Research Center. The results as determined by electrophoresis, showed that the appropriate primers could distinctly amplify DNA of E. tarda and E. ictaluri.
