Description: The genus Corynebacterium comprises about 50 species of a phenotypically diverse group of bacteria. Some of them (30) are animal and plant pathogens, while other are saprophytes (feeding on dead organics). They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. The name Corynebacterium comes from a Greek word that means "club" which in fact is the appearance of the cell arrangements of some species that undergo a so called snapping division (cells "snap apart" forming sharp angles). Corynebacterium ulcerans is commonly associated with dairy animals and unpasturized dairy products. This organism has been implicated in bovine mastitis and can cause skin infections and a diptheria-like disease in humans.
