Staph bacteria can also enter body via urinary catheters, intravenous lines, or other implanted medical devices. Bacteria can additionally be present on tattoo needles that have not been properly cleaned and needles used to inject particularly if they are shared or reuse. Some Staph infections of skin are contagious and can pass from one person to through Skin - to - Skin contact. Staph bacteria can also survive on objects or such as bedsheets, towels, or clothing. Touching contaminated items is way to get Staph. Infections are common in group living facilities, such as college dorms or prisons, where people are in close with one another.

Taking certain medicines, including insulin, or chemotherapy, can increase your chance of contracting Staph. Additionally, Staph infections more common in individuals who use illegal drugs. Sometimes Staph bacteria spreads through medical tubing, such as dialysis tubes, urinary breathing tubes, feeding tubes, or intravascular catheters.
Hair on body and scalps grow out of hair follicles. Bacteria can enter skin through damaged hair follicles, causing infection called folliculitis. Shaving or plucking hair on scalp frequently touching scalp, wearing tight hats or other headgear having hot, damp skin for extended time, folliculitis causes red rings to develop around each hair follicle. This may pain or itching. People may find relief redness and itching by applying warm washcloth to skin. In some cases, person may to take medication for infection, but it will usually clear up on its own. If person knows what has caused their folliculitis, they can prevent and treat condition more easily. For example, if they have recently shaven head, they can make extra effort to prevent bacteria from entering their skin. This may include washing more frequently changing headgear more often.
Most commonly, folliculitis is caused by infection of superficial or deep hair follicle.S However, this condition may also be caused by fungal species, viruses and can even be noninfectious in nature. Several of causative agents of Folliculitis are listed below and include: superficial bacterial Folliculitis - most common form of Folliculitis, This particular condition is usually caused by bacteria Staphylococcus aureus. It should be noted that both methicillin - sensitive and methicillin - resistant forms this bacteria can cause Folliculitis. Gram - negative bacterial Folliculitis - Commonly referred to as hot tub Folliculitis, this condition results from pseudomonas aeruginosa. It typically arises after exposure to contaminated water from either improperly treated swimming pool or hot tub. Other bacteria that may cause condition include Klebsiella and Enterobacter. Folliculitis from these bacteria commonly arises after long - use of oral antibiotics. Pityrosporum Folliculitis - this particular form of Folliculitis is fungal, caused by Malassezia species of fungi such Malassezia furfur. Typically found in adolescence secondary to activity of their sebaceous glands, and is commonly found in cape - like distribution over patients ' shoulders, back, and neck. Clinical suspicion of this condition should arise patients diagnosed with acne that has failed to respond or even worsen, after antibiotic treatment. Viral Folliculitis - Most commonly caused by herpes virus, it could also be by Molluscum contagiosum, but this is far rarer. Folliculitis due to herpes virus presents in much same way as bacterial folliculitis with exception that papulovesicles and / or plaques are usually present and not pustules. Another key to diagnosis of this condition is that lesions typically appear either groups or clusters. Demodex Folliculitis - type of Folliculitis by mite Demodex folliculorum. This particular type of Folliculitis is controversial as Demodex mite is normally present in pilonidal sebaceous area of skin. Estimates are that 80 to percentage of all humans may carry this mite. Eosinophilic Folliculitis - this particular brand of Folliculitis is found predominantly those with advanced HIV or those with low CD4 counts. Although non - HIV variation of this condition has been seen as rare side effect in patients undergoing chemotherapy. While exact etiology of this condition is unknown, studies suggest it could result from inflammatory disease secondary to immune dysregulation and that there may be associated underlying infection. Most commonly, this condition presents as erythematous and urticarial follicular papules, usually on scalp, face, and neck with rare pustules.
