The strains were extremely homogeneous in protein and lipopolysaccharide preparations as observed by sodium-dodecyl-sulfate polyacrylamide gel electrophoresis. Only minor variations were observed in the structural O-side chain subunits in three isolates; however, such variation did not preclude antigenic recognition by two<span> </span><i>E. ictaluri</i><span> </span>antisera in either microagglutination or Western blot immunoassays. The antigenic homogeneity of<span> </span><i>E. ictaluri</i><span> </span>was further demonstrated by microagglutination assays with both formalin-killed and heat inactivated cellular antigens. The minimal degree of antigenic variability observed suggested that most isolates of<span> </span><i>E. ictaluri</i><span> </span>compose a single antigenic serotype.</p></div>
