Opportunistic coryneform organisms--residents of human skin.

Opportunistic infections are usually caused by endogenic flora originated from physiological flora. In this context we studied coryneform bacteria recovered from deeper layers of epidermis of the forehead (278 isolates) and the back (196 isolates) of healthy men. It was observed that coryneform bacteria are in dynamic equilibrium with coagulase-negative staphylococci and they amount 4,7% of resident aerobic flora.
