Pathogenesis of Experimental Edwardsiella ictaluri Infections in Channel Catfish (Icta lurus punctatus)

Abstract: The lesions observed in channel catfish (Ictalurus punctatus) as a consequence of exposure to Edwardsiella ictaluri via gut and water were studied. Channel catfish fingerlings were exposed to 1010 bacterial cells via the gut and placed in tanks with unexposed fish. Both groups of fish were sampled periodically over a 35-day period. The gut-exposed fish exhibited gross signs of a systemic infection within 2 wk. Enteritis, hepatitis, interstitial nephritis, and myositis, all of which began as acute reactions and… Show more

“…The disease caused by this Gram-negative bacterial pathogen is considered to be one of the most economically important in commercial catfish farms in the southeastern USA (Francis-Floyd et al 1987). The number of documented disease outbreaks due to E. ictaluri represented more than 50 O/O of all fish mortalities in Mississippi in 1985and 1986(Francis-Floyd et al 1987. Chen & Kumlin (1989) first reported the occurrence of an epizootic in channel catfish in California during the summer of 1987.…”

“…E. ictaluri infects and colonizes catfish internal lymphoid tissues upon oral or bath infection, making it a promising strain to develop effective live attenuated recombinant vaccines for the catfish industry. Both gut and olfactory organs are the primary sites of invasion of E. ictaluri in natural outbreaks (5). E. ictaluri crosses the intestinal mucosa of channel catfish in 15 min after oral inoculation with 10 9 CFU (6).…”
