    There have been increased reports of outbreaks of enteric redmouth disease (ERM) caused by Yersinia ruckeri in previously vaccinated salmonids in Europe, with some of these outbreaks being attributed to emergent non-motile, Tween negative, biotype 2 isolates. To gain information about their likely origins and relationships, a geographically and temporally diverse collection of isolates were Cited by: Yersinia ruckeri is the causative agent of enteric redmouth disease, a bacterial infection of marine and freshwater fish. The disease mainly affects salmonids, and outbreaks have significant economic impact on fish farms all over the world.

Yersinia ruckeri (Y. ruckeri) is a Gram-negative rod-shaped enterobacterium and the causative agent of enteric red mouth disease (ERM), one of the most serious septicemic bacterial disease of salmonid fish species ().It has been reported that Y. ruckeri has been increasingly widespread and been detected as an important pathogen of salmonid fish in many other countries (2–6 Cited by: 1.

Enteric redmouth disease (ERM) is a serious septicemic bacterial disease of salmonid fish species. It is caused by Yersinia ruckeri, a Gram-negative rod-shaped enterobacterium.

It has a wide host range, broad geographical distribution, and causes significant economic losses in the fish aquaculture by: Fish phagocytes exhibit the discriminatory capacity for their targets common to other vertebrates but the basis for this is ill-understood.

Surface phenomena are involved and the role of surface charge and the hydrophilic properties of the phagocyte and particle have been considered (Weir and Ögmundsdóttir, ; Van Oss, ).

It is however. Yersinia ruckeri causes enteric redmouth of fish, and the infection usually results in a hemorrhagic septicemia. Yersenia aldovae, Y. frederiksenii, Y. intermedia, and Y. kristensenii were previously biogroups of Y.

enterocolitica, and their role in human and animal infections has not been established. Yersinia pestis is the casual agent of human plague. Plague is basically a disease of rats and many.

The biotypes, serotypes and outer membrane protein-types (OMP-types) of isolates of Yersinia ruckeri were analysed in an attempt to identify clonoal groups and to examine to further detail the Author: Robert L Davies.

Yersinia ruckeri, a Gram-negative rod-shaped enterobacterium.

It has a wide host range, broad geographical distribution, and causes significant economic losses in the fish aquaculture industry. In addition, this medium proved useful for isolating Y. ruckeri from river water samples.

Serological properties of Yersinia ruckeri The terms serovar, serotype, and serogroup have been used interchangeably by various authors; in addition, both roman and Cited by: Yersinia ruckeri was obtained from one of largely asymptomatic rainbow trout from a farm on the Isle of Man, an island off the North West coast of Great Britain.

This is the first reported isolation of Y. ruckeri from the Isle of Man. The isolate was phenotypically and serologically indistinguishableCited by: 3. Although Yersinia enterocolitica is usually transmitted through contaminated food and untreated water, occasional transmission such as human-to-human, animal-to-human and blood transfusion associated transmission have also identified in human by: Yersinia ruckeri is a species of Gram-negative bacteria, known for causing enteric redmouth disease in some species of fish.

Biotype 2 (BT2) variants of the bacterium Yersinia ruckeri are an increasing disease problem in U.S. and European aquaculture and have been characterized as serovar 1 isolates that lack both peritrichous flagella and secreted phospholipase activity.

The emergence of this biotype has been associated with an increased frequency of enteric redmouth disease (ERM) outbreaks in previously vaccinated salmonid Cited by: Aims: The study investigated antigen characteristics of biotype (bt) 1 and bt 2 isolates of Yersinia ruckeri.

Methods and Results: The cell surface characteristics of Y. ruckeri were compared for their antigenic characteristics using polyclonal antibodies that revealed that both biotypes had a homogenous whole‐cell protein antigenic profile. Notable differences in the antigenic properties.

Eight bacteriophages effective against Yersinia ruckeri, the enteric redmouth disease bacterium, were isolated. Phage YerA41, a tailed icosahedral virus isolated from sewage enrichments, lysed 34 of 35 strains of Y. ruckeri serovar I, but was inactive against 15.

The virulence in rainbow trout (Oncorhynchus mykiss) of 32 isolates of Yersinia ruckeri, representing a range of biotypes, serotypes, and OMP-types, was examined.

Virulence was assayed in fish of average weight g by bath challenge for 1 h with approximately 5 × 10 7 cells per by: Y. ruckeri had low levels of hybridization with Hafnia alvei, Salmonella cholerae-suis subsp. arizonae, and Yersinia enterocolitica in dot blots and colony hybridization.

Phylogeographic patterns and population genetic structure of Yersinia ruckeri, the pathological agent of enteric redmouth disease (ERM) in salmonids, were investigated on the basis of concatenated multiloci sequences from isolates of different phenotypes obtained between and from diverse areas and hosts.
