Disease relevance of Rahnella

• Group B embraces two phylogenetically separate Serratia clusters, a lineage containing Yersinia species, Rahnella aquatica, Ewingella americana, and also the highly related pair Hafnia alvei and Obesumbacterium proteus [1].

High impact information on Rahnella

• Expression of the lsrA gene from Rahnella aquatilis, encoding levansucrase, is tightly regulated by the growth phase of the host cell; low-level expression was observed in the early phase of cell growth, but expression was significantly stimulated in the late phase [2].
• A major outer membrane protein of Rahnella aquatilis functions as a porin and root adhesin [3].
• A 38-kDa major outer membrane protein (OMP) was isolated from the nitrogen-fixing enterobacterium Rahnella aquatilis CF3 [3].
• Fifty-one Rahnella aquatilis and R. aquatilis-like strains from water, snails and human sources were characterized by routine biochemical tests, carbon source utilization tests, DNA relatedness (hydroxyapatite method) and 16S rRNA sequencing [4].
• Structures of two putative O-specific polysaccharides from the Rahnella aquatilis 3-95 lipopolysaccharide [5].

Chemical compound and disease context of Rahnella

• Structure of the O-polysaccharide of the lipopolysaccharide of Rahnella aquatilis 1-95 [6].
• Formation of guaiacol in chocolate milk by the psychrotrophic bacterium Rahnella aquatilis [7].
• Two strains in phenotypic group III, which is negative for indole production and positive for gas production from D-glucose, were identified as Rahnella aquatilis [8].
• Two polysaccharide preparations (OPSI and OPSII) were obtained by mild acid degradation of the lipopolysaccharide of Rahnella aquatilis 3-95 [5].
• Rahnella strains were also naturally resistant or intermediate to cefazolin, cefuroxime and loracarbef [9].

Gene context of Rahnella

• Molecular characterization of the growth phase-dependent expression of the lsrA gene, encoding levansucrase of Rahnella aquatilis [2].
• The application of polyacrylamide gel electrophoresis of soluble proteins, DNA-DNA hybridizations and API 20 E systems has shown that Rahnella aquatilis might also be encountered as a contaminant in lager beer breweries [10].
