A 22-year-old man arrives at the clinic with a painful lesion on his upper back. A few days ago, the patient noticed a little sore papule that grew in size and became red and unpleasant. He's had three identical lesions on his upper back in the last six months, all of which were treated with incision and drainage, as well as medications. The patient has no additional medical problems and is not on any drugs. He does not smoke, drink, or use illegal drugs. On physical examination, his right upper back has a 3-cm painful pustule with surrounding erythema. Below is a Gram staining of purulent discharge from the lesion. Which of the following most likely predisposed this patient to recurrent infections?
