Draft Genome Sequence of the Type Strain Aeromonas salmonicida subsp. salmonicida ATCC 33658
Here, we report the draft genome sequence of the type strain Aeromonas salmonicida subsp. salmonicida ATCC 33658 isolated from Salmo salar The size of the genome is 4,728,143 bp with a G+C content of 58.5%. The A. salmonicida subsp. salmonicida ATCC 33658 genome lacks essential virulence genes that were likely lost during genomic rearrangements.
متن کاملSiderophore production by Aeromonas salmonicida.
Growth under conditions of iron-restriction and the production of siderophores was examined in 21 typical and 14 atypical strains of Aeromonas salmonicida. With the exception of one atypical strain, all strains grew and multiplied in the presence of the high-affinity iron chelators ethylenediamine di(o-hydroxyphenylacetic acid), alpha, alpha'-dipyridyl or transferrin. Chrome azurol S agar was u...
متن کاملThe mosaic architecture of Aeromonas salmonicida subsp. salmonicida pAsa4 plasmid and its consequences on antibiotic resistance
Aeromonas salmonicida subsp. salmonicida, the causative agent of furunculosis in salmonids, is an issue especially because many isolates of this bacterium display antibiotic resistances, which limit treatments against the disease. Recent results suggested the possible existence of alternative forms of pAsa4, a large plasmid found in A. salmonicida subsp. salmonicida and bearing multiple antibio...
متن کاملAeromonas salmonicida subsp. salmonicida in the light of its type-three secretion system
Aeromonas salmonicida subsp. salmonicida is an important pathogen in salmonid aquaculture and is responsible for the typical furunculosis. The type-three secretion system (T3SS) is a major virulence system. In this work, we review structure and function of this highly sophisticated nanosyringe in A. salmonicida. Based on the literature as well as personal experimental observations, we document ...
متن کاملContribution of the type III secretion system (TTSS) to virulence of Aeromonas salmonicida subsp. salmonicida.
The recently described type III secretion system (TTSS) of Aeromonas salmonicida subsp. salmonicida has been linked to virulence in salmonids. In this study, three TTSS effector genes, aexT, aopH or aopO, were inactivated by deletion, as was ascC, the gene encoding the outer-membrane pore of the secretion apparatus. Effects on virulence were assayed by live challenge of Atlantic salmon (Salmo s...
