Answer and topic summary
The answer is A. Staphylococcus aureus
Folliculitis is essentially inflammation of the hair follicle or sebaceous gland. It is limited to the epidermis; it can be infectious or non-infectious. The most common pathogen indicated in infectious folliculitis is Staphylococcus aureus. Clinical features include pruritus, erythema located at the site of hair follicles, papules/pustules, etc. Diagnosis is often clinical. Management for mild folliculitis includes topical mupirocin or clindamycin; when extensive or severe disease is suspected, systemic antibiotic therapy is warranted (e.g., cephalexin or dicloxacillin; if MRSA is suspected, then oral Bactrim, doxycycline, or clindamycin).
