General Information: 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.

Subject: NC_009480:739395 Clavibacter michiganensis subsp. michiganensis NCPPB 382, complete

Lineage: Clavibacter michiganensis; Clavibacter; Microbacteriaceae; Actinomycetales; Actinobacteria; Bacteria

General Information: Phytopathogen that causes bacterial wilt and canker of tomato (Lycopersicon esculentum). This is considered to be the most important bacterial disease of tomato causing substantial economic losses worldwide. Bacteria enter the plant by wounds on root or stem and then find their way into the xylem allowing a massive systemic colonization. The first stage of the disease is characterized by unilateral wilting of leaves. Wilting then spreads to all leaves, canker lesions develop on the stem and the plant dies. If infection occurs at a late stage of plant development, plants can survive and yield fruit that may have spots, so called bird's eyes. Often the seeds will be infected and this has been the major source for outbreaks of Clavibacter michiganensis subsp. michiganensis infections in agriculture. Members of the Clavibacter genus are known to produce antimicrobial compounds.
