These were the first two 'bugs' that my girls cultured. They were not treated for them unless they had symptoms, such as increased cough.
As for the antibiotic he is on, it would depend on what antibiotics the bacteria showed they were resistant to. Did they send you a copy of the actual report, or just a letter? If you get the report, it will show (or should) show the bacteria it is sensitive to.
I would assume that you will not be treated any differently during clinic appts. I know we were not. I really didn't even see a big change when my girls started culturing MRSA (except when admitted in the hospital they are isolated). Kayla just started culturing Cepacia, and now we are made to go to clinic on seperate days from the other CF children. I understand this and appreciate it. But I didn't see a difference with H. Flu or Staph.
Sorry they didn't call you with the results. At least then you could ask questions and get some peace immediately than worrying about it<img src="i/expressions/face-icon-small-sad.gif" border="0">
