Technical Abstract: Arbitrarily Primed Polymerase Chain Reaction (AP-PCR) utilizing a Enterobacterial Repetitive Intergenic Consensus PCR primer (ERIC II) to genomically subtype 19 isolates of Edwardsiella ictaluri from channel catfish from throughout the Southeastern United States, an American Type Culture Collection reference strain, and an isolate from a walking catfish, Clarias batrachus from Thailand. Four major subgroupings of E. ictaluri were observed. These subgroups were distributed with the following prevelences: subgroup 1 (55%), subgroup 4 (20%), 2 (15%), and 3 (10%). Biochemical analysis showed biochemical homogeneity among isolates and was not useful for discriminating between isolates.
