Query: NC_016843:547149 Treponema pallidum subsp. pertenue str. Gauthier chromosome,
Lineage: Treponema pallidum; Treponema; Spirochaetaceae; Spirochaetales; Spirochaetes; Bacteria
General Information: This strain was isolated in Brazzaville, the Republic of Congo in 1960. Treponema pallidum subsp. pertenue causes 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_006085:854500 Propionibacterium acnes KPA171202, complete genome
Lineage: Propionibacterium acnes; Propionibacterium; Propionibacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Isolated from human skin. Acne causing bacterium. This bacterium is the most common gram-positive, non-spore forming, anaerobic rod encountered in clinical specimens. The causative agent of acne, it typically grows as an obligate anaerobe. Some strains are aerotolerant, but still show better growth as an anaerobe. It has the ability to produce propionic acid, as its name suggests. It also has the ability to produce catalase along with indole, nitrate, or both indole and nitrate. Propionibacterium resembles Corynebacterium in morphology and arrangement, but is non-toxigenic.It is a common resident of the pilosebaceous (hair follicle) glands of the human skin. The bacteria release lipases to digest a surplus of the skin oil, sebum, that has been produced. The combination of digestive products (fatty acids) and bacterial antigens stimulates an intense local inflammation that bursts the hair follicle. Since acne is caused in part from an infection, it can be suppressed with topical and oral antibiotics such as clindamycin, erythromycin, or tetracycline. Some other forms of therapy include chemicals that enhance skin removal or slow the production of sebum.
