    abstract = {<I>Edwardsiella ictaluri</I>, the causative agent of Enteric Septicemia of Catfish (ESC) has been isolated from other fish species from ten families, but not white perch (<I>Morone americana</I>).  In order to determine whether white perch could be experimentally-infected with <I>E. ictaluri</I>, white perch were captured from the Corsica River in Centreville, Maryland, USA, using a castnet.  Four perch and 4 cultured channel catfish were experimentally challenged by intraperitoneal injection with 1.0×10<SUP>7</SUP> colony-forming units of <I>E. ictaluri</I>/fish.  While channel catfish exhibited clinical signs characteristic of ESC, the white perch showed limited and non-specific clinical signs.  All challenged fish died within 48 h and 97.5% of nare, brain, head kidney, intestine and posterior kidney samples from the catfish and perch produced growth on 5% de-fibrinated sheep blood agar.  The colonies were formed by oxidase-negative, Gram-negative rods and biolog analysis identified the isolates as <I>E. ictaluri</I> (Probability = 99%; SI = 0.91).  Despite some differences in clinical presentation, both the channel catfish and white perch were susceptible to <I>E. ictaluri</I> and died due to acute systemic infections.  The results of this study demonstrated that white perch are experimentally susceptible to <I>E. ictaluri</I> and this study provides the first description of <I>E. ictaluri</I> infection in white perch.}
