Draft genome sequence of the fish pathogen Flavobacterium columnare strain CSF-298-10 Genome announcements

Jason P Evenhuis, Scott E LaPatra, Joerg Graf

2017

We announce here the draft genome assembly of Flavobacterium columnare CSF-298-10, a strain isolated from an outbreak of columnaris disease at a commercial trout farm in Hagerman Valley, Idaho, USA. The complete genome consists of 13 contigs totaling 3,284,579 bp, with an average G+C content of 31.5% and 2,933 predicted coding genes.

Oxidized derivatives of linoleic acid in pediatric metabolic syndrome: is their pathogenic role modulated by the genetic background and the gut microbiota? Antioxidants & Redox Signaling

2017

We tested whether oxidized linoleic acid metabolites (OXLAM) are associated with pediatric metabolic syndrome (MetS) and a proatherogenic lipoprotein profile in 122 obese adolescents. Furthermore, we examined whether genetic and metagenomic factors can modulate plasma OXLAM concentrations by genotyping the fatty acid desaturase 1/2 (FADS) gene and by characterizing the gut microbiota. Subjects with MetS (n = 50) showed higher concentrations of 9- and 13-oxo-octadecadienoic acid (9- and 13-oxo-ODE) than subjects without MetS (n = 72). Both metabolites were associated with an adverse lipoprotein profile that was characterized by elevated very small-dense low-density lipoprotein (p

The flagellar master operon flhDC is a pleiotropic regulator involved in motility and virulence of the fish pathogen Yersinia ruckeri Authors Journal of applied microbiology

Anna K Snyder Jozwick, Joerg Graf, Timothy J Welch

2017

To investigate the function of the master flagellar operon flhDC in the fish pathogen Yersinia ruckeri and compare the effect of a constructed flhD mutation to a naturally occurring fliR mutation causing loss-of-motility in emergent biotype 2 (BT2) strains.

Delineation of Taxonomic Species within Complex of Species: Aeromonas media and Related Species as a Test Case Frontiers in microbiology

Emilie Talagrand-Reboul, Frédéric Roger, Jean-Luc Kimper, Sophie M Colston, Joerg Graf, Fadua Latif-Eugenín, Maria José Figueras, Fabienne Petit, Hélène Marchandin, Estelle Jumas-Bilak, Brigitte Lamy

2017

Aeromonas media is an opportunistic pathogen for human and animals mainly found in aquatic habitats and which has been noted for significant genomic and phenotypic heterogeneities. We aimed to better understand the population structure and diversity of strains currently affiliated to A. media and the related species A. rivipollensis.
