Different bacterial flora. Illustration of three different type of bacteria forming part of a bacterial flora. Rod-shaped bacteria (blue and green) are next to spherical bacteria (red). Some bacteria are non-pathogenic and form part of the normal bacterial flora found on human skin and in the human intestines. These 'good' bacteria help prevent harmful pathogenic (disease-causing) bacteria from taking hold and causing an infection.
