Scanning electron micrograph of normal dog skin and hair. Staph. intermedius is a nomad on healthy skin, who takes advantage of changes in the environment and becomes pathogenic. Baytril has excellent activity against Staph. intermedius, as well as secondary Gram-negative invaders.   Scanning electron micrograph of dog hair arising from the follicle infundibulum. Permanent secretion of sebum towards the skin surface clears hair follicles of bacteria.   Dermatitis and folliculitis caused by staphylococci. The follicle is partially filled with pus and inflammatory cell infiltration is clearly visible. Baytril's readily penetrates pus and cellular degradation products to reach bacteria covered under layers of inflammatory material.   Deep bacterial pyoderma with purulent inflammatory reaction, vasculitis and accumulation of numerous macrophages. Baytril concentrates in phagocytes. Macrophages were proposed to act as transport medium for active drug to the site of infection. (Pictures courtesy of Prof. Dr. W.
