I agree with Dr. V. A staph infection is nothing to fool around with and needs serious medical attention, preferably in a vet clinic. Do you now the specific infection since not all staph infections are alike- some are worse than others and some are more antibiotic resistant. Giving your pet more antibiotics may actually just make her situation worse. You need to know what meds she is on and a plethora of info - best found by blood panels and other testing by a vet before you proceed. This is not an area for a breeder! Ever!
