Causes of Folliculitis
Staphylococcus aureus (S. aureus)
Almost any organ system can be infected by S. aureus. Most frequently, S. aureus strains first infect the skin and its structures (for example, sebaceous glands, hair follicles) or invade damaged skin (cuts, abrasions). Sometimes the infections are relatively limited (such as a sty, boil, furuncle, or carbuncle), but other times they may spread to other skin areas (causing cellulitis, folliculitis, or impetigo).
