Query: NC_016842:546661 Treponema pallidum subsp. pertenue str. SamoaD chromosome, complete
Lineage: Treponema pallidum; Treponema; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated in Western Samoa in 1953. Treponema pallidum subsp. pertenue causes the chronic and disfiguring illness called yaws. The disease starts as a skin infection causing persistent ulcers and progresses to form tumor-like masses. This disease tends to infect children and is common in rural areas in Africa, Southeast Asia and equatorial South America.
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.
