<s>[INST] My son developed a staph infection after a pectus bar implant. He was given a course of antibiotics and then had another surgery. The incision site opened back up and was once again diagnosed with staph. His Dr. did not culture either time and has always said it looks good My son now has to have the bar removed due to the infection spreading to the bar. What is the recomended follow up for staph and how often should it be tested to ensure the staph has been cleared up? [/INST] Hello, Thank you for your contact to Chat Doctor. I understand your concern. If I am your doctor I suggest you Staphylococcus aureus is very notorious strain known as Methicillin Resistant Staphylococcus aureus, which resistant to routinely prescribed Chat Doctor.  I suspect the same in your child. You can get tested it in the laboratory. You can use mupirocin to clear such strain of bacteria. After treatment swab from such a patient must be clear to declare patient as a free from bacteria. I will be happy to answer your further concerned can contact me. Chat Doctor.
