Can you have staph infection in or on the butt?

Sure.: Staph lives all over (ubiquitous), common skin germ; certainly can cause skin infection on buttock. Not a likely bowel germ, so not likely to be "in" butt, unless spread from skin source or spread from elsewhere. Can get perianal abscess (pus pocket) from inflamed/infected anal glands-usually not staph though.

Bacteria: Many people carry staph bacteria and never develop staph infections. If you have a staph infection, there's a good chance that it stemmed from bacteria you've been carrying around for some time.These bacteria can also be transmitted from person to person. Because staph bacteria are so hardy, they can live on inanimate objects such as pillowcases or towels long enough to transfer to the next person.
