My sister and I are both nurses. I'm an O.R. nurse in Michigan, she's a Med/Surg nurse in San Diego. A week ago she was bitten by her dog and went to the local urgent care to have it looked at. It was cultured and she was put on antibiotics and given a week off from work because of the open wound. She was just notified that the wound cultured out with MRSA. Her antibiotic was changed to doxycycline (allergic to Amoxicillin) and not given any specific details when to return to work other than the week she originally recieved. She is worried about returning to work, still being infectious, etc., because she works with immuno-compromised patients. Does anyone know how long it takes the antibiotics to eradicate MRSA in a puncture wound? How would they be able to tell when she's no longer infective? She talked to the urgent care Dr. and the pharmacist who dispensed the doxycycline, but neither of them could tell her what she needed to know. Does she need to have repeat skin swab/cultures? I've never dealt with this, so I'm clueless as to what to tell her too. Thanks for any input... Kellijojo
