Folliculitis Symptoms Patients often present with erythematous, folliculocentric papules that may be painful. The papules are usually small, uniform in size.

Causes Most causes of folliculitis are infectious - Staphylococcus aureus being the most common. The inflammation and puss is a predominantly from neutrophilic cell population. Other causes include Klebsiella, Enterobacter, Proteus or Pseudomonas aeruginosa (all gram negative bacteria). They may also be caused by viruses (e.g. HSV) Epidemiology The lifetime prevalence of folliculitis has not been reported.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
