ictaluri strain were evaluated for each mutant. METHODS. In this study, three isogenic mutants were constructed that introduced deletions in esrC, eseG, and evpC. EsrC is a T3SS-encoded protein that regulates expression of multiple virulence genes, including the T3SS effector EseG and the T6...
ictaluri strain, and it was avirulent by immersion and oral routes. Tissue persistence studies indicated that the mutant maintained the ability to invade following immersion exposure, but no viable cells were detected after 48–72 h. Significant levels of protection from disease were demonstrated ...

Moreover, a label free quantitativeproteomicsworkflow was used to study how salinity affects theproteomeof...
中文摘要:根据GenBank中鮰爱德华氏菌 Edwardsiella ictaluri外膜微孔蛋白N( porin N)基因序列(GenBank No: NC_012779.2)设计了1对引物,预计目的片段大小为381 bp。通过对反应体系和条件的优化,并进行特异性试验、敏感性试验及人工感染组织样品检测,建立了一种快速检测鮰爱德华氏菌的PCR方法。结果表明,在所检测的鮰爱德...
The three species recognised in the genus Edwardsiella are Edwardsiella ictaluri, Edwardsiella tarda (synonym Edwardsiella anguillimortifera) and Edwardsiella hoshinae. A further fish-pathogenic species, Edwardsiella piscicida, has been proposed (Abayneh et al., 2013). E. ictaluri is a serious path...
Outbreaks of disease caused by the infection of Edwardsiella ictaluri in ayu Plecoglossus altivelis have been reported in rivers in Japan since 2007. In this study, we performed comparative proteomic analysis between the virulent strain FPC1091 and the less virulent strain FPC1214 to identify virulence...
ictaluri [36, 37], pEIB202 (43 kb) found in E. piscicida strain EIB202 is medium sized. In some Edwardsiella strains, there are no plasmids. While some of the plasmids, i.e. pEI1/2 encoding T3SS genes, are highly associated to the bacterial pathogenesis [34, 36], many of the ...
ictaluri two days after they were weighed as part of the 6-week feeding study. Fish from both groups averaged 24.2 ± 0.5 g/fish at the beginning of the challenge. An E. ictaluri isolate (Strain 93e146) from a natural outbreak (confirmed by the Mississippi State Uni- versity, Aquat...

ictaluri vaccine strain in AQUAVAC-ESC harbors such plasmids, so that the use of this vaccine will not directly contribute to the pool of bacteria carrying plasmid-borne resistance. Antimicrobial sensitivity testing of the E. ictaluri parent isolate and vaccine strain demonstrated that both were ...
