Both of my girls culture MRSA. Actually my older one was culturing it when she was dx wit CF at 14 months of age. My younger daughter started culturing it at three months of age. They are now 13 and 12. When they start feeling poorly, they are almost always started on Bactrim for the MRSA. My older daughter has also taken oral Zyvox for the MRSA.
Older daughter has been hospitalized five times, and every time treated with three antibiotics, one always been Vancomycin for the MRSA, although last time she was on IV Zyvox instead. Younger daughter has NEVER been hospitalized due to lung issues. Only one time to clear up her sinuses prior to sinus surgery, and she was on IV Zyvox (she has a true Vanc allergy, not just Redmans...) for the MRSA.
Older daughters FEV1 is still in the 80s+, younger daughter is 100%+. Older daughter also cultures PA, Burkholderia Multivorans and has ABPA. She has moderate lung damage, but not sure what bacteria is causing more of the problems...
