| tenacibaculum geojense sp. nov., isolated from seawater. | a gram-staining-negative, non-flagellated, non-spore-forming bacterial strain motile by gliding, designated ycs-6(t), was isolated from seawater on the southern coast in korea, and its taxonomic position was investigated by using a polyphasic approach. strain ycs-6(t) grew optimally at 30°c and in the presence of 2 % (w/v) nacl. phylogenetic analyses based on 16s rrna gene sequences revealed that strain ycs-6(t) fell within the clade comprising tenacibaculum species, clustering with tenacibaculu ... | 2011 | 21257684 |
| experimentally induced marine flexibacteriosis in atlantic salmon smolts salmo salar. i. pathogenicity. | tenacibaculum maritimum causes marine flexibacteriosis in many cultured fish species, including atlantic salmon salmo salar in tasmania, australia. several aspects of the pathogenicity of this bacterium were investigated in naive atlantic salmon smolts using different isolates, growth conditions and doses to produce a model of infection. we found that t. maritimum is pathogenic to atlantic salmon using either marine shieh's or marine ordal's culture medium. the use of aeration in broth culture p ... | 2010 | 21387991 |
| a review of infectious gill disease in marine salmonid fish. | infectious gill diseases of marine salmonid fish present a significant challenge in salmon-farming regions. infectious syndromes or disease conditions affecting marine-farmed salmonids include amoebic gill disease (agd), proliferative gill inflammation (pgi) and tenacibaculosis. pathogens involved include parasites, such as neoparamoeba perurans, bacteria, such as piscichlamydia salmonis and tenacibaculum maritimum, and viruses, such as the atlantic salmon paramyxovirus (aspv). the present level ... | 2011 | 21401646 |
| tenacibaculum dicentrarchi sp. nov. a novel marine bacteria of the family flavobacteriaceae isolated from european sea bass (dicentrarchus labrax, l.). | a novel gram-negative rod-shaped gliding bacterial strain designated 35/09t was isolated from diseased european sea bass (dicentrarchus labrax, l.) in spain. colonies were pale yellow-pigmented with uneven edges and did not adhere to the agar. the dna g+c content was 31.3 mol%. 16s rrna gene sequence analysis indicated affiliation to the genus tenacibaculum (family flavobacteriaceae, phylum bacteroidetes). the sequence similarity of the isolate with respect to the type strains of other members o ... | 2011 | 21460137 |
| tenacibaculum jejuense sp. nov., isolated from a coastal seawater. | aa gram-staining-negative, strictly aerobic and rod-shaped bacterium, designated strain cnuric013t was isolated from seawater collected on the coast of jeju island, south korea. phylogenetic analyses based on 16s rrna gene sequences showed that the strain cnuric013t belonged to the genus tenacibaculum, a member of the family flavobacteriaceae. sequence similarities between the novel strain and the type strains of recognized tenacibaculum species were 93.6-96.0 %, the highest values being with te ... | 2011 | 21460140 |
| tenacibaculum sp. associated with winter ulcers in sea-reared atlantic salmon salmo salar. | coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared atlantic salmon salmo salar l. have been reported in norway since the late 1980s, and moritella viscosa has been established as an important factor in the pathogenesis of this condition. as routine histopathological examination of winter ulcer cases in our laboratory revealed frequent presence in ulcers of long, slender rods clearly different from m. viscosa, a closer study focusing on these bacteria was conducted. field cases o ... | 2011 | 21790066 |
| experimentally induced marine flexibacteriosis in atlantic salmon smolts salmo salar. ii. pathology. | the fish disease marine flexibacteriosis is characterised by necrotic lesions on the body, head, fins, and occasionally gills, with erosive lesions on the external surface as the prominent clinical sign. in australia, the main species affected are atlantic salmon salmo salar and rainbow trout oncorhynchus mykiss in sea-cage culture in tasmania. using a dose-dependent trial to determine pathology, 2 forms of the disease were noted in atlantic salmon. the acute form occurs within 2 to 3 d after in ... | 2011 | 21848120 |
| characterization of isr region and development of a pcr assay for rapid detection of the fish pathogen tenacibaculum soleae. | the aims of this work were to characterize the 16s-23s internal spacer region of the fish pathogen tenacibaculum soleae and to develop a pcr assay for its identification and detection. all t. soleae strains tested displayed a single internal spacer region class, containing trna(i) (le) and trna(a) (la) genes; nevertheless, a considerable intraspecific heterogeneity was observed. however, this region proved to be useful for differentiation of t. soleae from related and n ... | 2011 | 22092820 |
