Involvement of tolQ and tolR genes in Edwardsiella ictaluri virulence [PDF]

Microbial Pathogenesis, 2016
Edwardsiella ictaluri is a Gram-negative intracellular facultative pathogen causing enteric septicemia of channel catfish (ESC). The Tol system, consisting of four envelope proteins TolQ, TolR, TolA, and TolB, are required for colicin import and contributes to bacterial virulence in several pathogenic bacteria.

Exploring the genetic diversity of Edwardsiella ictaluri in Vietnamese striped catfish (Pangasianodon hypophthalmus) farms over a 20-year period

Frontiers in Marine Science, 2023
Since first being identified in 1999, disease outbreaks from Edwardsiella ictaluri remain a significant health challenge for the farmed catfish sector in Vietnam. To better understand the population structure of E.

The aspartate-semialdehyde dehydrogenase of Edwardsiella ictaluri and its use as balanced-lethal system in fish vaccinology. [PDF]

PLoS ONE, 2010
asdA mutants of gram-negative bacteria have an obligate requirement for diaminopimelic acid (DAP), which is an essential constituent of the peptidoglycan layer of the cell wall of these organisms.

Attenuation, persistence, and vaccine potential of an Edwardsiella ictaluri purA mutant [PDF]

Infection and Immunity, 1997
In this study, an adenine-auxotrophic strain of Edwardsiella ictaluri was constructed and its virulence, tissue persistence, and vaccine efficacy were evaluated. A clone containing the purA gene was isolated from an E. ictaluri genomic library, sequenced, and shown to have an overall sequence identity of 79.3% at the nucleotide level and 85.7% at the ...

Bioencapsulation and Colonization Characteristics of Lactococcus lactis subsp. lactis CF4MRS in Artemia franciscana: a Biological Approach for the Control of Edwardsiellosis in Larviculture [PDF]

, 2018
Predominance of beneficial bacteria helps to establish a healthy microbiota in fish gastrointestinal system and thus to reduce emerging pathogen. In this study, the colonization efficacy of Lactococcus lactis subsp.

Immunofluorescent test for simultaneous detection of Edwardsiella ictaluri and Flavobacterium columnare [PDF]

Diseases of Aquatic Organisms, 2006
Enteric septicemia of catfish (ESC) and columnaris disease are 2 bacterial diseases significantly affecting the aquaculture industry, and thus rapid diagnosis of disease is imperative for making judicious management decisions. A rapid indirect fluorescent antibody (IFA) test with antibody conjugated fluorochromes having 2 different spectral properties (
