Lineage: Actinosynnema mirum; Actinosynnema; Pseudonocardiaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Isolation: Blade of grass from Raritan River NJ; Country: USA; Temp: Mesophile; Temp: 10-30C; Habitat: Soil. This bacterium produces the antibiotic nocardicin A. Soil dwelling, nonmotile aerobe it has fine hyphae which form aerial and substrate mycelia. Motile spores are borne on synnemata, compact groups of erect hyphae. It produces nocardicin antibiotics and is able to inhibit growth of several Gram-positive bacteria as well as some filamentous fungi and yeasts.

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.
