<unk> es are caused by a high-density infection of (usually) common bacteria which collect in one place or another for any variety of reasons. Anal<unk> es, without treatment, are likely to spread and affect other parts of the body, particularly the groin and rectal lumen. All<unk> es can progress to serious generalized infections requiring lengthy hospitalizations if not treated. Historically, many rectal<unk> es are caused by bacteria common in the digestive system, such as E. coli. While this still continues often to be the case, there has recently been an increase in the causative organism being staphylococcus, as well as the difficult to treat community-acquired methicillin-resistant S. aureus. Because of the increasing appearance of more exotic bacteria in anal<unk> es, microbiological examination will always be performed on the surgical exudate to determine the proper course of any antibiotic treatment.
