Bacterial folliculitis represents a bacterial infection of the hair follicles of the skin. It can be superficial or deep and is contagious. Although it usually affects the exposed areas of the arms, legs and beard area of the face, it can appear anywhere.
Causes of Folliculitis, Bacterial
Most commonly, bacterial folliculitis is caused by staphylococcus bacteria. These bacteria infect the hair follicles, usually after minor skin injury, and spread to other parts of the body by fingernails. The infection is frequently spread to the nose. Pseudomonas bacteria may also cause the infection. It is seen following the use of contaminated hot tubs or spas. Although this type of infection is not as common, its occurrence is on the rise.
Signs and Symptoms of Folliculitis, Bacterial
Bacterial folliculitis produces pustules, that are small white blisters with pus inside. They are usually yellow-white, surrounded by narrow red halos. Typically, they are small, 1 mm to 2 mm in size. They may occur in small or large clusters. There may be a discharge of blood-stained pus made from dead cells. Some of the pustules are pierced by hair fibers while others may be adjacent to hair follicles.
