title: Citrobacter koseri in scalp folliculitis.
abstract: Gram-negative folliculitis, an uncommon condition, is most often seen in older patients who have acne and who either have received prolonged courses of antibiotic therapy or have used antibacterial cleansers that selectively inhibit gram-positive organisms. Citrobacter infections are uncommon, and dermatologists seldom encounter them. In the past, these infections occurred in hospitals, particularly in neonatal intensive care units. Bacteremias also occur in elderly or immunocompromised patients. In this article, we present a case of Citrobacter koseri scalp folliculitis in an otherwise healthy patient.
