UNLABELLED Yersinia ruckeri is the etiological agent of enteric redmouth (ERM) disease of farmed salmonids. Enteric redmouth disease is traditionally associated with rainbow trout (Oncorhynchus mykiss, Walbaum), but its incidence in Atlantic salmon (Salmo salar) is increasing. Yersinia ruckeri isolates recovered from diseased Atlantic salmon have been poorly characterized, and very little is kn...

The effect of oral vaccines against bacterial fish diseases has been a topic for debate for decades. Recently both M-like cells and dendritic cells have been discovered in the intestine of rainbow trout. It is therefore likely that antigens reaching the intestine can be taken up and thereby induce immunity in orally vaccinated fish. The objective of this project was to investigate whether oral ...

Abstract Background Yersinia ruckeri is a pathogen that can cause enteric redmouth disease in salmonid species, damaging global production of economically important fish including rainbow trout ( Oncorhynchus mykiss ). Herein, we conducted the transcriptomic profiling spleen samples from at 24 h post- Y. infection via RNA-seq an effort to more fully understand their immunological responses. Res...

The aim of this study was to assess the effect oral vaccination against Yersinia ruckeri based on oxidative stress biomarkers in gills rainbow trout (Oncorhynchus mykiss Walbaum). vaccine consisted three Y. strains (O1 serotype) that originated from cultured different farms, where fish exhibited clinical signs enteric redmouth disease. concentrated incorporated into food; treatment delivered ti...

From the winter 2002 to spring 2006, 126 moribund rainbow trout with clinical signs of external body haemorrhages around and within the oral cavity were sampled from 10 rainbow trout farms situated in the northwest and west of Fars province, Iran and examined for the detection and identification of Yersinia ruckeri, the causative agent of enteric redmouth disease. Fish kidneys were cultured ase...
