Subclinical Edwardsiella ictaluri Infection of Wild Ayu Plecoglossus altivelis

Infection Status of Ayu and Other Wild Fish with <i>Flavobacterium psychrophilum</i> and <i>Edwardsiella ictaluri</i> in the Tama River, Japan

“…Our results and the details described above indicate that river environmental factors that might affect the occurrence of E. ictaluri infection should be investigated in addition to the impact of high water temperatures. E. ictaluri has been isolated from many fish species (Tensha and Hatama, 2009;Evance et al, 2011;Plumb and Hanson, 2011), and the isolates from ayu showed pathogenicity against several native fish species in Japan (Hassan et al, 2012). In our survey, E. ictaluri was detected in 6 wild fish species other than ayu (Fig.…”

“…3). Hassan et al (2012) have reported that E. ictaluri is ubiquitous in the river environment, and that the infection cycle might be completed between environmental E. ictaluri and susceptible hosts in the riverine settings. Thus, many wild fish species inhabiting the Tama River basin might play an important role in the infection dynamics of E. ictaluri.…”

Full-genome sequence of a novel myovirus, GF-2, infecting Edwardsiella tarda: comparison with other Edwardsiella myoviral genomes

“…Genomic DNA was extracted from 100 ll of purified phage particles (10 11 PFU/ml) using a standard phenol-chloroform extraction method. A comparison of the genomes of GF-2, MSW-3 and E. ictaluri myovirus phage PEi21 [7,24] was carried out by BLAST analysis. Titanium sequencing platform.…”

Complete Genome Sequence of the Edwardsiella ictaluri-Specific Bacteriophage PEi21, Isolated from River Water in Japan

“…Recently, E. ictaluri -specific phages have also been isolated from rivers in Japan, in association with E. ictaluri infections of ayu (7). These phages exhibited the morphology of the family Myoviridae (7).…”
