Query: NC_014909:619407 Candidatus Blochmannia vafer str. BVAF chromosome, complete genome
Lineage: Blochmannia vafer; Blochmannia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Candidatus Blochmannia is an obligate bacterial associate of Camponotus and related ant genera. Blochmannia vafer was isolated from Camponotus vafer workers and larvae collected from a single colony in the Coronado National Forest near Portal, Arizona, USA. Blochmannia is located within bacteriocytes, where the bacterial cells float freely in the host cytoplasm, and within oocytes of queens.
Subject: NC_006177:3457637 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.
