Siderophore 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 کاملAcquisition of iron by Aeromonas salmonicida.
The ability of six typical and three atypical strains of Aeromonas salmonicida to sequester Fe3+ from the high-affinity iron chelators ethylenediaminedihydroxy-phenylacetic acid, lactoferrin, and transferrin was determined. Typical strains were readily able to sequester Fe3+ and used two different mechanisms. One mechanism was inducible and appeared to involve production of a low-molecular-weig...
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...
متن کاملAeromonas salmonicida subsp. salmonicida type strain does not possess a type III secretion system.
A study by Chacón et al. examined the presence of type III secretion genes in Aeromonas species of clinical significance (2). The authors demonstrated, by dot blot hybridization at 50°C, that the prevalence of these genes was high in clinical strains of A. hydrophila and A. veronii, particularly those isolated from extraintestinal infections. However, the positive control used in this study was...
