A boil also called a furuncle is a deep folliculitis infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. Individual boils clustered together are called carbuncles.Most human infections are caused by coagulase-positive S. aureus strains notable for the bacteria’s ability to produce coagulase an enzyme that can clot blood.
