Oligochitosan modulates non-specific immunity against Edwardsiella ictaluri infection in hybrid groupers Epinephelus fuscoguttatus f × E. lanceolatus m.

Diseases of Aquatic Organisms
Edwardsiella ictaluri is a pathogenic bacterium that poses a significant threat to the economic viability of aquaculture. However, the effects of E. ictaluri infection on the non-specific immune response of hybrid grouper and the regulatory mechanisms of

Identification and characterization of a two-component hemolysin from Edwardsiella ictaluri

Veterinary Microbiology, 2005
The channel catfish pathogen Edwardsiella ictaluri possesses hemolysin activity, and strains that are adapted for growth in fish tend to have greater hemolysin activity than strains that are adapted for in vitro growth conditions. To investigate its potential role in virulence, an isogenic hemolysin mutant strain of E. ictaluri R4383 was constructed by

Chemical characterization of lipopolysaccharide from Edwardsiella ictaluri, a fish pathogen

Canadian Journal of Microbiology, 1988
The chemical components of lipopolysaccharide (LPS) from the fish pathogen Edwardsiella ictaluri (Ed. ictaluri) were analyzed by SDS–PAGE, gas chromatography, and spectrophotometry, and compared with those of Salmonella typhimurium and Escherichia coli 0111:B4. Only four to five low molecular weight species of LPS from Ed.

Susceptibility of European catfish (Silurus gianis) to Edwardsiella ictaluri

Journal of Applied Ichthyology, 1987
Summary European catfish (Silurus glanis) were tested for their susceptibility to the bacterium Edwardsiella ictaluri. The LD50 of E. ictaluri when injected into European catfish was 5.4 × 106 compared to 7.1 times; 104 for channel catfish (Ictalurus punctatus). E.

Responses of channel catfish (Ictaluris punctatus) fed iron-deficient and replete diets to Edwardsiella ictaluri challenge

Aquaculture, 1997
Abstract Juvenile channel catfish were fed egg-white-based diets with or without 20 mg supplemental iron/kg from iron methionine for 13 weeks. Subsequently, fish from each treatment were divided into two groups and fed either the iron-deficient or replete diets for another 4 weeks.

Plasmid-Mediated Romet Resistance ofEdwardsiella ictaluri

Journal of Aquatic Animal Health, 1993
Abstract Romet®, a potentiated sulfa drug composed of five parts sulfadimethoxine and one part ormetoprim, is used to treat channel catfish Ictalurus punctatus infected with Edwardsiella ictaluri, the causal agent of enteric septicemia of catfish (ESC). Recently, several Romet-resistant isolates of E.

Biochemical, Biophysical, and Serological Homogeneity ofEdwardsiella ictaluri

Journal of Aquatic Animal Health, 1989
Abstract Edwardsiella ictaluri is the causative agent of enteric septicemia of catfish, which, during the past 5 years, has become the most serious infectious disease problem of cultured channel catfish Ictalurus punctatus. We compared 40 isolates of E. ictaluri from different geographical regions and host fish species. From the biophysical tests, a pH

The virulence and immune protection of Edwardsiella ictaluri HemR mutants in catfish

Fish & Shellfish Immunology, 2018
Edwardsiella ictaluri is a Gram-negative facultative intracellular rod, causing enteric septicemia of catfish (ESC). Several heme uptake systems have been described in bacterial pathogens, most of which involve outer membrane proteins (OMPs). We have shown recently that heme/hemoglobin receptor family protein (HemR) is significantly up-regulated in E ...

Susceptibility of Delta Select and Delta Control Channel Catfish lines to experimental Edwardsiella ictaluri and Edwardsiella piscicida infection

North American Journal of Aquaculture
The Delta Select line of Channel Catfish Ictalurus punctatus was established in 2006 and has undergone five generations of genetic selection, specifically targeting increased growth rate and carcass yield, and was released to U.S. catfish farmers in 2020.
