What is gram negative folliculitis?
Gram negative folliculitis is an acne-like disorder caused by a bacterial infection. Gram negative bacteria include Escherichia coli, Pseudomonas aeruginosa, Serratia marcescens, Klebsiella and Proteus species. The term Gram negative refers to the staining pattern of the organisms in the laboratory. Certain bacteria do not take up a stain known as Gram. Gram negative folliculitis may result from long term treatment with tetracycline or topical antibiotics.
