Gram-negative folliculitis is a type of skin infection that can occur as a complication of long-term antibiotic therapy in acne patients. It is characterized by pustules and cysts.
Causes[edit]
Gram-negative folliculitis is caused by various types of gram-negative bacteria, including Escherichia coli, Klebsiella, Proteus, and Pseudomonas aeruginosa. These bacteria can overgrow in the nasal passages and then spread to the skin, causing infection.
Symptoms[edit]
The main symptoms of gram-negative folliculitis are small, pus-filled bumps (pustules) and larger, deeper lumps (cysts) on the skin. These can be painful and may leave scars.
Diagnosis[edit]
Diagnosis of gram-negative folliculitis is based on the patient's medical history, physical examination, and laboratory tests. The doctor may take a sample of the pus from a pustule or cyst and send it to a laboratory for bacterial culture and sensitivity testing.
Treatment[edit]
Treatment of gram-negative folliculitis usually involves stopping the antibiotic therapy that caused the condition and starting a new antibiotic that is effective against gram-negative bacteria. In severe cases, isotretinoin may be used.
Prevention[edit]
Prevention of gram-negative folliculitis involves careful use of antibiotics, especially in acne patients. Long-term antibiotic therapy should be avoided if possible.
