Lolabee is right. A staph infection is commonly what is seen, but there are specific clinical names for each type of bacteria. You should be able to get that information from your nurse. I'm sure it's in your charts.
This is the type of information that's important for you to know and part of the reason why you need an infectious disease doctor on your case. Each type of infection has specific antibiotics that work on it and you want someone who is very familiar with fighting a particular infection deciding what is best for you.
As the patient, you are a partner with your doctors in your medical treatment. You can be a better advocate for your care if you ask a lot of questions and be sure you understand each treatment option that is proposed. The "why" behind everything is critical. I hope you're having lots of detailed discussions with all your doctors and nurses.
