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 1965 and 2009 from diverse areas and hosts. Sequence analyses revealed genetic differentiation among subpopulations with the ...
BACKGROUND Enteric Redmouth Disease (ERM), caused by Yersinia ruckeri, is one of the most important infectious diseases in rainbow trout (Oncorhynchus mykiss) aquaculture in Europe. More recently, non-motile vaccine resistant isolates appear to have evolved and are causing disease problems throughout Europe, including Germany. The aim of this study was to analyse the variation of biochemical an...
Bacterial cold water disease, enteric red mouth disease and frunculosis are the common bacterial diseases of fish worldwide. The etiologic agents of these diseases are Flavobacterium (F.) psychrophilum, Yersinia (Y.) ruckeri and Aeromonas (A.) salmonicida subsp. salmonicida, respectively. In this study, a multiplex polymerase chain reaction (m-PCR) method with YER8/10-Fer3/4-FP1/3 primer pairs ...
Five strains of a newly described Escherichia species, Escherichia albertii, were extensively characterized by conventional biochemical methods and by commercial identification panels. E. albertii is an indole-negative species that ferments D-mannitol but not D-xylose. Because these strains are not included in the databases of commercial systems at present, they were most often identified as Ha...
A case of skin alterations and mortalities associated with Yersinia ruckeri in two summer old common carp after over-wintering a hibernation pond is described the present work. The disease was characterised mainly by erosions around orbital area fish. bacterium cultivated on Columbia agar identified MALDI-TOF, biochemical characteristics sequencing 16s rDNA. Parasitological virological examinat...
Bu çalışmada, bitkilerden doğal ekstraksiyon işlemiyle elde edilen ve su ürünleri yetiştiriciliğinde tatlandırıcı yem katkı maddesi olarak kullanılan Silvafeed TSP (tannik asit) antimikrobiyal duyarlılığı araştırıldı. Balıklarda önemli ekonomik kayıplara neden olan Aeromonas hydrophila, Pseudomonas fluorescens, Yersinia ruckeri Vibrio anguillarum izolatlarına karşı tannik asitin farklı konsantr...
A strain of Carnobacterium sp., isolated from the intestine of Atlantic salmon, was evaluated for potential use as a probiotic for salmonids. In vitro studies demonstrated antagonism against Aeromonas hydrophila, A. salmonicida, FlaÕobacterium psychrophilum, Photobacterium damselae subsp. piscicida, Streptococcus milleri, Vibrio anguillarum and V. ordalii but not towards Debaryomyces hansenii, ...
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...
Background: Enteric Redmouth (ERM) disease also known as Yersiniosis is a contagious disease affecting salmonids, mainly rainbow trout. The causative agent is the gram-negative bacterium Yersinia ruckeri. The disease can be diagnosed by isolation and identification of the causative agent, or detection of the Pathogen using fluorescent antibody tests, ELISA and PCR assays. These diagnostic metho...
In the present study bacteriophages isolated from rainbow trout farms and sewage treatment plants were genetically identified and their effectiveness on Yersinia ruckeri isolates from clinical cases of red mouth disease was investigated. Fish samples suspected to red mouth disease were collected from rainbow trout farms located in west Azerbaijan. Y. ruckeri, the causative agent of red mouth d...
