*Hurley staging: Hurley, stage 1 lesions correspond to nodules or abscesses, single or multiple, without sinus tracts or hypertrophic scars. Stage 2 lesions are single or multiple but non-confluent lesions with sinus tracts and formation of scarring. Stage 3 lesions correspond to diffuse or nearly diffuse involvement of multiple interconnected sinus tracts or abscesses across the entire area.
†Each lesion was sampled 1 or 2 times. Open lesions with purulent drainage were sampled by swabbing of the purulent drainage. On consent of the patient, closed, nonsuppurative lesions were sampled only by biopsy or needle aspiration.
