Comparison of Vietnamese and US isolates of Edwardsiella ictaluri

Diseases of Aquatic Organisms, 2013
We compared Edwardsiella ictaluri from striped catfish in Vietnam with US channel catfish isolates. Biochemical analyses and sequencing of the 16S rRNA gene confirmed that the Vietnamese isolates were E. ictaluri. Comparison using rep-PCR fingerprinting demonstrated no significant differences between the isolates, but plasmid analysis indicated that ...

Construction and evaluation of an Edwardsiella ictaluri fhuC mutant

Veterinary Microbiology, 2013
Edwardsiella ictaluri is a Gram-negative facultative intracellular pathogen causing enteric septicemia in channel catfish. Iron is an essential micronutrient needed for bacterial virulence, and to acquire iron, many Gram-negative bacteria secrete ferric iron chelating siderophores. The ferric hydroxamate uptake (Fhu) system consists of four genes (fhuC,

Proteome analysis of Edwardsiella ictaluri

PROTEOMICS, 2009
Abstract Edwardsiella ictaluri is a facultative intracellular Gram‐negative bacterium causing enteric septicemia of catfish (ESC), the most prevalent disease affecting farm‐raised channel catfish in the United States.

Distribution ofEdwardsiella ictaluriin California

Journal of Aquatic Animal Health, 1994
Abstract Wild and domestic populations of channel catfish Ictalurus punctatus were examined to determine the distribution of the disease called enteric septicemia of catfish (ESC) in California. The causative agent of ESC, Edwardsiella ictaluri, was isolated from five separate sites in California.

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 ...

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

Recovery of Edwardsiella ictaluri from danio (Danio devario)

Aquaculture, 1985
Abstract A disease outbreak in the danio ( Danio devario ) resulted in the isolation of Edwardsiella ictaluri as the etiologic agent. This isolate was compared with typical E. ictaluri and found to give identical reactions. It was also pathogenic for channel catfish. This is the second isolation of E. ictaluri from non-ictalurid fish.

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.

Survival of Edwardsiella ictaluri in Pond Water and Bottom Mud

The Progressive Fish-Culturist, 1986
Abstract Edwardsiella ictaluri, the causative agent of enteric septicemia of catfish, is involved in about one-third of all disease cases in diagnostic laboratories where channel catfish (Ictalurus punctatus) is the predominant species examined. Edwardsiella ictaluri causes disease primarily when water temperatures range from 18°C to 28°C; these ...

The structure of the antigenic O-polysaccharide of the lipopolysaccharide of Edwardsiella ictaluri strain MT104

Carbohydrate Research, 2005
The structural characterization of the antigenic O-polysaccharide component of the lipopolysaccharide produced by the fish pathogenic bacterium Edwardsiella ictaluri MT104 was undertaken by the application of NMR spectroscopy and chemical analysis. The O-chain was found to be a linear polymer of a repeating tetrasaccharide unit composed of D-glucose, 2-
