Purpose: There has been a recent, rapid increase in prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) among patients with Cystic Fibrosis (22% across US CF centers in 2009). Some epidemiologic studies suggest possible worse outcomes, a recent analyses showing this with chronic but not intermittent MRSA. Given the chronic difficult to treat lung infections in CF it is unclear how the onset of MRSA should be approached. This randomized, controlled, interventional study seeks to determine if an early eradication protocol is effective for eradication of MRSA and will provide an opportunity to obtain data regarding early clinical impact of new isolation of MRSA.
Participants: Cystic fibrosis patients with new isolation of MRSA from their respiratory culture on a routine clinic visit.
Procedures (methods): Randomized, open-label, multi-center study comparing use of an eradication protocol to an observational group who receives the current standard of care i.e. treatment for MRSA only with pulmonary exacerbations.

No Intervention: Observational
Subjects are tracked and not treated for their MRSA. If the subject reaches a protocol defined exacerbation within the first 28 days then they will be treated per choice of their primary Pulmonologist.
- MRSA Culture Status [ Time Frame: Day 28 ]Proportion of subjects with a negative culture for MRSA at Day 28.
- Antibiotic Use (Proportion of Subjects) [ Time Frame: 6 months ]Proportion of subjects treated with oral, inhaled, and IV antibiotics over the 6 month study.
- Antibiotic Use (Days of Use Per Subject) [ Time Frame: 6 months ]Days of use of oral, inhaled, and IV antibiotics over the 6 month study.
- Pulmonary Exacerbations [ Time Frame: 28 days ]Proportion of subjects with a protocol-defined pulmonary exacerbation (PE) between baseline and day 28 who are treated with antibiotics active against MRSA.
