Query: NC_016612:3087615 Klebsiella oxytoca KCTC 1686 chromosome, complete genome
Lineage: Klebsiella oxytoca; Klebsiella; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This bacterium can cause spontaneous infectious spondylodiscitis (SIS), an uncommon cause of low back pain in adults, but most commonly described in children. This species can be differentiated from Klebsiella pneumoniae by its inability to produce indole from tryptophan.
Subject: NC_006177:520055 Symbiobacterium thermophilum IAM 14863, complete genome
Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria
General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
