Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems‚ open wounds or medical devices implanted in their

Gram-positive‚ aerobic‚ nonmotile‚ rod-shaped bacteria related to the Actinomycetes. They do not form spores or branch as do the actinomycetes‚ but they have the characteristic of forming irregular shaped‚ club-shaped or V-shaped arrangements in normal growth. They undergo snapping movements just after cell division which brings them into characteristic arrangements resembling Chinese letters. The genus Corynebacterium consists of a diverse group of bacteria including animal and plant pathogens‚ as well
