Document Summary
Bacterial infections acquired through skin, mucosa, and bloodstream from human and endogenous sources. Caused by staphylococcus aureus pyogenic bacteria (pus-causing) Furunculosis= involves deeper layers of the skin, gland, or hair follicle. Carbuncles= encompass more than one hair follicle and invade deep tissue: transmission: Reservoir of infection= people s. aureus inhabits the nostrils of almost everyone at some point. Over 60% of population carries the organism continuously in any one year. Self-infection= responsible for at leas 1/3 of infections: symptoms: When folliculitis occurs, tiny rea pustules appear. Boils appear as hard, painful nodules, commonly on the neck, face, armpits and buttocks generally enlarge and rupture, discharging pus. Carbuncle= extremely painful, deep abscess that drains through multiple openings: treatment: Folliculitis generally needs no treatment other than keeping the area clean. For boils and carbuncles, pressure should be kept off site and hot compresses will help. Especially common in the newborn and in children, particularly during hot, humid weather.
