TranscriptomicsThe immediate global responses of Aliivibrio salmonicida to iron limitations
Iron is an essential micronutrient for all living organisms, and sequestering of iron and the virulence of pathogenic bacteria are believed to be correlated. As the defense mechanisms, potential hosts therefore keep the level of free iron inside the body to a minimum. The iron metabolism is well stu...

TranscriptomicsExpression profiling of a spf deletion mutant suggests biological roles and mRNA targets for Spot 42 in the fish pathogen Aliivibrio salmonicida
Spot 42 was discovered in Escherichia coli nearly 40 years ago as an abundant, small and unstable RNA. Its biological role remained obscure until it was shown to cause discoordinate expression of the galactose operon (gal operon). Recently Spot 42 has also been implicated in having broader roles in ...

TranscriptomicsPrediction, microarray and Northern blot analyses identify new intergenic small RNAs in Aliivibrio salmonicida (LB medium vs. iron-limited condition)
Bacterial small RNAs (sRNAs) are trans-encoded regulatory RNAs that typically bind mRNAs by short sequence complementarities and change the expression of the corresponding proteins. Some of the well characterized sRNAs serve critical steps in the regulation of important cellular processes, such as q...

TranscriptomicsPrediction, microarray and Northern blot analyses identify new intergenic small RNAs in Aliivibrio salmonicida (wild type vs. LitR mutant)
Bacterial small RNAs (sRNAs) are trans-encoded regulatory RNAs that typically bind mRNAs by short sequence complementarities and change the expression of the corresponding proteins. Some of the well characterized sRNAs serve critical steps in the regulation of important cellular processes, such as q...

TranscriptomicsGlobal responses of Aliivibrio salmonicida to hydrogen peroxide
Aliivibrio salmonicida causes “cold-water vibriosis” (or “Hitra disease”) in fish, including marine-reared Atlantic salmon. During development of the disease the bacterium will encounter macrophages with antibacterial activities such as production of damaging reactive oxygen species (ROS). T...
