Sequencing and Analysis of the Edwardsiella ictaluri Plasmids

Plasmid, 2001
To determine possible functions of the Edwardsiella ictaluri plasmids, pEI1 and pEI2, we analyzed the sequence of both plasmids. Plasmid pEI1 is 4807 bp, with 51% G + C, and 23 possible open reading frames of 40 amino acids or greater. Plasmid pEI2 is 5643 bp, with 51% G + C, and 24 possible reading frames.

A MEDIUM FOR THE SELECTIVE ISOLATION OF EDWARDSIELLA ICTALURI

Journal of Wildlife Diseases, 1990
A selective medium, called Edwardsiella ictaluri medium (EIM), has been formulated for the isolation of Edwardsiella ictaluri. The medium inhibits the growth of most gram-negative bacteria, except Proteus sp., Serratia marcescens and some isolates of Aeromonas hydrophila and Yersinia ruckeri.

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.

Characterization of a virulence related hypothetical protein in Edwardsiella ictaluri [PDF]

, 2022
Although the biochemical characterization of E. ictaluri, the subsequent disease progression of enteric septicemia of catfish (ESC), and the associated pathologic lesions are well characterized, the mechanism of invasion of E. ictaluri into a susceptible

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.

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

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 ...

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.

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 ...
